BONUS Q&A Episode!

It’s our bonus question and answer episode, which turned out to be ridiculously long but hopefully interesting! Further listening/watching: The Axolotl Song ~~~Buy my books!~~~ Whiskers used to have two eyes and a nose. In the background, Dracula (left) and Poe (right): Black squirrel! King cobra! Pufferfish, puffed: Dog nose: Show transcript: Welcome to the bonus Q&A episode of Strange Animals Podcast! I’m your host, Kate Shaw, and this is a little extra episode where I answer listener questions. So let’s jump right into it. To start us off, Simon and Thia wanted to know how I first became interested in animals. I really don’t know! When I was little, I didn’t want to play with dolls, I wanted to play with my stuffed animals. I actually have a toy cat named Whiskers who I’ve had since I was four. Whiskers is older than all my teeth! I especially loved horses as a kid and since my family couldn’t afford to buy me a horse, I took riding lessons and read everything I could find about horses, fiction and nonfiction. All that reading about horses led to reading about other animals, and the more I read, the more interested I became in animals of all kinds. Next, Melissa of the awesome podcast Bewilderbeasts asked, “What was the fact or episode that really slapped you out of left field, like, ‘I didn’t see that coming AT ALL’?” OH MY GOSH, how many times has that happened to me? The most astounding fact I can think of isn’t actually about an animal at all but about trees. While I was researching the Temnospondyl episode, which had a related Patreon episode that ran at about the same time, I came across the fact that when trees first developed, nothing could break down the tough compound called lignin that hardens a tree’s cells to make wood and bark. When a tree died, its trunk just stayed where it fell forever, and this happened for at least 50 million years and possibly 100 million years. 100 million years of tree trunks just lying all over the ground! You wouldn’t be able to walk anywhere! You’d have to climb over hundreds of millions of fallen tree trunks, although naturally as the years passed the older ones would get buried deeper and deeper in the earth. But there would always be more! This blew my mind, and later I came back to it, determined to do more research and make sure it was accurate. I did a whole lot of research, because it just didn’t seem possible, and that information ended up in episode 214. As for an animal that blew my mind, I still have trouble believing ice worms are real. They’re worms that live in snow and ice! We covered them last August in episode 185 and I’m still reeling. Next, Llewelly asks what my favorite extinct animal is, or animals. Why would you make me choose? This is so hard. Okay, fine, I’ll narrow it down to hoofed Pleistocene megafauna like the giant deer and elasmotherium and so many other animals with weird horns and ossicones and things like that. What really gets me is that they lived so recently! Many of them only died out 11,000 years ago, and some were probably around much more recently in a few isolated areas. It also really reminds me to appreciate the megafauna that’s still around. We live at the same time as giraffes! Next, Richard E. asked, “Does your job involve the study of animals and/or is the pod something that you really wanted to do?” Tracie also asked what my background is, if I’m a professor or zookeeper or something similar. Helenka also asked my background and how I got interested in strange animals. I’m kind of embarrassed that I never have pointed out that I’m not an animal expert, to steal a phrase from the awesome podcast Varmints! I actually work as a test proctor, AKA invigilator, in a large community college, so my work doesn’t have anything to do with animals. My background is in elementary education although I didn’t teach long. Basically I got my K-8 teaching certification and M.Ed., did some substitute teaching afterwards, and ended up getting my current job instead of taking a teaching position. I still love teaching, so when I decided I wanted to start a podcast, I knew it would be nonfiction. My undergraduate degree is in English literature, and I took so many history courses that I minored in history almost by accident, so I’m really good at research and can write an essay about any topic in the world in very little time. I didn’t know it when I was in college, which was long before podcasts existed anyway, but I have the perfect background for creating a nonfiction podcast. Liesbet has three questions about the podcast: what inspired me to start it, what motivates me to keep going without missing any episodes, and what I enjoy most about it. I’m so pleased that someone noticed I’ve never missed a single episode! Not that it would be the end of the world if I did, of course, but if I did, I’d feel bad thinking about people who were looking forward to listening to the new episode and were disappointed when there wasn’t one.

I’m your host, Kate Shaw.   It’s our fourth annual updates and corrections episode, and to keep it especially interesting we’ll also learn about a mystery snake. Make sure to check the show notes for lots of links if you want to learn more about these updates.   First, we have a small correction from episode 222. G emailed with a link about a Florida man who was killed by a cassowary in 2019, so cassowaries continue to be dangerous.   We also have a correction from episode 188, about the hyena. I called hyenas canids at one point, and although they resemble canids like dogs and wolves, they’re not canids at all. In fact, they’re more closely related to cats than dogs. Thanks to Bal for the correction!   In response to the talking animals episode, Merike told about a dog who uses computer buttons to communicate. The dog is called Bunny and she’s completely adorable. I’ll link to her facebook page. I have my doubts that she’s actually communicating the way it looks like she is. She’s obviously a clever dog but I don’t think she understands the English language so well that she can choose verbs like “is” from her list of words. I think she’s probably mostly taking unconscious cues from her owner. But I would be happy to be proven wrong.   Following up from our recent deep-sea squid episode, a team of paleontologists studying ancient cephalopods 3-D printed some replicas of what the animals would have looked like while alive. Then they took the models into a swimming pool and other water sources to study how their shells affected the way they could move through the water. They discovered that a type of cephalopod with a straight shell, called an orthocone, probably mostly moved up and down in the water to find food and could have moved extremely fast in an upward or downward direction. A type of cephalopod with a spiral shaped shell, called a torticone, also spun slightly as it moved around. The same team has previously worked with 3-D models of ammonoids, which we talked about in episode 86. The models don’t just look like the living animals, they have the same center of balance and other details, worked out mathematically.   Speaking of ancient animals, a collector in London bought a fossil found in Morocco thinking it was part of a pterodactyl skull. When the collector asked a palaeontologist to identify it, it turned out to be a fossilized coelacanth lung. The collector donated the fossil for further study, and the palaeontologist, David Martill, worked with a Brazilian coelacanth expert, Paulo Brito, to examine the fossil.   The fossil dates to the Cretaceous, about 66 million years ago, and is bigger than any coelacanth lung ever found. Modern coelacanths grow a little over six feet long at most, or 2 meters, but the estimated length of this Coelacanth is some 16 ½ feet, or 5 meters. The fossil is being donated to a university in Morocco.   We talked about vampire bats way back in episode 11, and I love bats and especially vampire bats so I try to keep an eye on new findings about them. Everyone thinks vampire bats are scary and creepy, but they’re actually social, friendly animals who don’t mean to spread rabies and other diseases to the animals they bite. It just happens.   Vampire bats live in colonies and researchers have long known that if a female dies, her close relations will often take care of her surviving baby. Now we have evidence that at least sometimes, the adoptive mother isn’t necessarily related to the birth mother. It’s from a recently published article based on a study done in 2019.   A team researching how unrelated vampire bats form social bonds captured 23 common vampire bats from three different colonies and put them together in a new roost where their interactions could be recorded by surveillance cameras. One particular pair of females, nicknamed Lilith and BD, became good friends. They groomed each other frequently and shared food. If you remember from episode 11, vampire bats share food by regurgitating some of the blood they drank earlier so the other bat can lap it u

Before we get started, a quick announcement that I was a guest on a YouTube show called After Hours recently! I was there mostly to talk about my writing, but naturally animals came up too, especially cephalopods. There’s a link in the show notes if you want to watch the show. There is a little bad language, but not too bad and it’s more toward the end. Anyway, in a not-exactly coincidence, this week we’re going to look at some of the weirdest deep-sea squids known. Yes, weirder than the flying squid we talked about in episode 101. We don’t know much about any of them, but they’re definitely not what you expect when you think about squid. Let’s talk first about Asperoteuthis acanthoderma, the long-arm squid. It’s also sometimes called the thorny whiplash squid because it has little pointy tubercules in its skin and long, whiplike feeding tentacles. It lives in the deep sea and has been found in both the Pacific and the Atlantic Oceans, although very rarely. Despite its name, its feeding tentacles are much longer than its arms, although its arms are pretty long too. A squid’s body is generally more or less torpedo-shaped and is called a mantle. It has eight arms and two feeding tentacles that are usually longer than the arms. Many squid species have relatively short arms compared to mantle length. The feeding tentacles in long-arm squid are very slender and delicate, and they’re easily broken off after the animal dies and has washed around in the water for a while. One intact specimen has been found and measured, though. It had a mantle length of almost a foot and a half long, or 45 cm, but its total length, including the tentacles, was 18 feet, or 5.5 meters. The tentacles were 12 times the mantle length. Using that ratio, one large specimen found in 2007, which was 6 1/2 feet long, or 2 meters, including both mantle and arms, is estimated to have measured up to 24 feet long when it was alive, or over 7 meters. Most of its length is due to its incredibly long, thin feeding tentacles. So what does the long-arm squid eat with those long, delicate tentacles? We don’t know. We don’t know most things about the long-arm squid. Another species of Asperoteuthis is Asperoteuthis mangoldae. So little is known about it that it doesn’t even have an informal name. It was only described in 2007 and has only been found around the Hawaiian islands in the Pacific Ocean. It looks similar to the closely-related long-arm squid but without the incredibly long feeding tentacles. Instead, it has a sort of tail, so I nominate it to be called the long-tailed squid. It was caught on video for the first time in 2019 by a deep-sea rover. You’re going to hear a lot about deep-sea rovers in this episode. There are lots of links in the show notes to articles with embedded video of various squids, which is really interesting to watch. Asperoteuthis mangoldae is a long, slender squid. I couldn’t find any measurements so it could be that’s just not known right now. The species in this genus have an extension of the mantle, on the side opposite of the arms, that looks like an extra fin but that doesn’t seem to be used as a fin. In the long-tailed squid, this extra fin is as long as its mantle and arms and feeding tentacles all measured together. Most of the time the thin flaps of skin on either side of the so-called tail are extended, making it look like a really long fin, but when the squid feels threatened and needs to flee, it collapses the fin part around the middle section so that it reduces drag in

Episode 234: Sun Bears, Water Bears

Sign up for our mailing list! We also have t-shirts and mugs with our logo! Thanks to Enzo and Lux for their suggestions! Let’s learn about the sun bear and the water bear this week! Sun bear just chillin: Sun bears got long tongues: The water bear, AKA tardigrade, is not actually a bear. For one thing, it has twice the number of legs as bears have: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. It’s summer in the northern hemisphere, which means hot weather and sunshine and, if you’re lucky, a trip to the lake or ocean. To celebrate summertime, let’s talk about two animals suggested by Enzo and his sister Lux. They wanted to hear about the sun bear and the water bear. Get it? Sun and water? Enzo’s suggestion is the sun bear, which we talked about a little bit way back in episode 76, but which is a fascinating animal that deserves a lot more attention. The sun bear lives in southeast Asia in tropical forests and is most closely related to the black bear. It has silky black fur, although some are gray or reddish, and a roughly U-shaped patch of fur on its chest that varies in color from gold to almost white to reddish-orange. Its muzzle is short and is lighter in color than the rest of its face, usually gray. It has small ears too. It’s the world’s smallest bear, only around three feet long from head to tail, or 150 cm, and four feet tall when standing on its hind legs, or 1.2 meters. Researchers think its chest spot acts as a threat display. When a sun bear stands on its hind legs, the chest spot is really obvious, which may warn potential predators away. Even so, tigers and leopards will attack and eat sun bears. The sun bear spends a lot of time in trees, more than any other bear. It has long claws that it uses for climbing and to tear open logs to get at insect larvae. It eats a lot of termites and especially loves honey, which it licks from the hive with its long tongue–up to 10 inches long, or 25 cm. It also eats a lot of plant material, especially fruit and acorns. It will catch and eat birds and small animals, or sometimes larger animals like deer, but it mostly eats insects and fruit. The female sun bear makes her den in a hollow tree to give birth. She has one or two cubs at a time, and like other bear cubs they’re born extremely small and with their eyes and ears sealed shut. This is the case with animals like dogs and cats too, but newborn bears are tiny compared to how big the mother bear is. The eyes and ears continue developing after the cub is born, but it’s a few months before it can see and hear properly. A cub remains with its mother for almost three years. Other than mothers and babies, the sun bear is solitary. Adults don’t typically interact except to mate, although adult sun bears kept in captivity will play together. A 2019 study of sun bears came to a surprising conclusion that they communicate with each other by mimicking facial expressions. This is something humans do all the time, of course, and apes do too. Dogs also mimic facial expressions. Humans, apes, and dogs are all intensely social animals, so researchers have always assumed that the mimicking of facial expressions is important because of that sociability. I mean, that just makes sense. If you see a friend approaching and they have a big smile on their face, naturally you’re going to smile too. But here are these solitary bears with facial communication just as well-developed as in apes. Researchers think it may be a trait that’s so important to mammals as a whole that it develops even in species that don’t spend a lot of time interacting. The sun bear is threatened by habitat loss and hunting, but it does well in captivity and is popular in zoos. Conservation efforts are in place to protect the sun bear in the wild as well as continue a healthy captive breeding program around the world. Lux wanted to hear about the water bear, which is also called the tardigrade or the moss piglet. I can’t believe we haven’t covered the tardigrade before—we even have one in our new logo! Patrons may remember parts of this section from a Patreon bonus episode from 2017, but I’ve updated it a lot. The water bear isn’t a bear at all but a tiny eight-legged animal that barely ever grows larger than 1.5 millimeters. Some species are microscopic. Pictures of the water bear are taken with an electron microscope because otherwise they just look like a teensy little dot. There are about 1,300 known species of water bear and they all look pretty similar. It looks for all the world like a plump eight-legged stuffed animal made out of couch upholstery. It uses six of its fat little legs for walking and the hind two to cling to the moss and other plant material where it lives. Each leg has four to eight long hooked claws. It has a tubular mouth that looks a little like a pig’s snout or a bear’s snout. An extremophile is an organism adapted to live in a particular environment that’s considered extreme, like

Episode 233: The Astonishing Aye-Aye

Sign up for our mailing list! We also have merchandise! Thanks to Elaine, Molly, and Oliver for suggesting the aye-aye! I guess it’s an idea whose time has finally come. Further reading: Gimme six! Researchers discover aye-aye’s extra finger Ah yes, I have many many many fingers: S p i d e r h a n d s: A baby aye-aye (blep): Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. I can safely say that this week’s episode is brought to you by popular demand. It was suggested by not one, not two, but three different listeners, two of them very recently. Elaine wanted to know about the aye-aye, and then Molly wanted to know about the aye-aye, and then Oliver wanted to know about the aye-aye. I think it’s high time we all learned about the aye-aye, because it’s a weird and amazing animal. The aye-aye is a primate, specifically a type of lemur, but it doesn’t look like other lemurs. It kind of looks like a weird possum at first glance. Its shaggy fur is brown or yellowish but the hairs are tipped with white, which gives it a frosty appearance. Its face is white or pale gray. Its eyes are large, very round, and orange or yellow, and it has really big ears sort of like a bat’s ears. It grows up to three feet long, or 90 cm, including its really long tail. To picture what an aye-aye looks like, imagine a little monkey with brownish fur tipped with white, with a tail longer than its body that’s thickly furred like a squirrel’s tail. Its head looks like a squirrel or possum, but with big orangey staring eyes and big bat ears that are sort of stuck out to the sides of its head instead of on top. Its hind feet look like monkey feet with an opposing digit to help it grab onto branches, because it lives in trees. But its hands look like SPIDERS. The fingers of its hands are extremely long and thin like spider legs. That’s what it looks like. The aye aye’s fingers are long for an interesting reason, and if you don’t already know, I bet you would never be able to guess. Go on, guess. Just shout it out. I won’t hear it but everyone around you will hear you shout, “THE AYE-AYE’S FINGERS LOOK LIKE SPIDER LEGS BECAUSE IT WANTS TO SCARE PREDATORS INTO THINKING IT’S TWO SPIDERS WITH A MONKEY FRIEND.” You would be wrong, sorry, but that’s a good guess. No, the aye aye uses its fingers to find grubs and other insects hidden in rotting wood or under bark, just like a woodpecker. Here’s how that works, and you’re not going to believe it, but it’s true. The aye aye is a primate, which means it has five fingers just like monkeys and apes and humans, but again, they’re extremely long and thin. The middle finger is even thinner than the others. It looks like a jointed twig. If it really was a spider, other spiders would ask what happened to that leg because it’s so much thinner than the other legs. The aye aye uses the thin finger to tap-tap-tap on tree branches and trunks at night, and it listens with its huge ears to the echoes of its tapping. That’s echolocation, just like bats and a few other animals use to navigate, but the aye aye uses it to listen for hollow places in the tree where insects are hiding. It can also hear the tiny movements of insects. Its ears are just that sensitive. When the aye aye locates an insect, it chews a hole into the wood and then uses its long fingers to fish the insects out. It has claws at the end of its fingers that help it catch the insects, although the claws are actually just claw-like fingernails. Primates don’t have claws, we have nails, and that includes the aye-aye. It doesn’t just eat insects, though. It eats fruit, seeds, various kinds of fungus, honey, flowers, and flower nectar. It actually eats more plant material than insects. It may also eat frogs, since some frogs in Madagascar lay their eggs in small holes in trees that are filled with rainwater, but it’s also possible that the aye-aye doesn’t care about frogs or frog eggs or tadpoles. Frogs definitely use the little holes the aye-aye chews as perfect little nurseries for their eggs. The aye-aye is native to the forests of Madagascar and mostly lives along the east coast. It spends the day sleeping in trees, in a nest it makes out of twigs and dead leaves. Since it may travel more than a mile at night while it forages, it doesn’t always sleep in the same nest. It can make a new one in less than an hour, and then it crawls inside and wraps its long tail around it and falls asleep, cozy and warm. The aye-aye hardly ever comes down to the ground. It’s mostly solitary except during mating season, although sometimes a few aye ayes will forage together. When aye-ayes do forage together, it’s usually a male and female, or one female and more than one male, or just two or more males. Female aye-ayes are more aggressive than males and they don’t want anything to do with other females. The aye aye has so many non-primate characteristics that I hardly know where to start. For one thing, it’s nocturnal. Very few

Episode 232: Almost Domesticated

Sign up for our mailing list! Buy our merch! Thanks to “dog freak Ruby,” we’re going to learn about some animals that aren’t exactly domesticated but aren’t really wild either. Further reading: Memories of Ángela Loij Mongolian horse and its person: Mongolian horses: OH MY GOSH HEART HEART HEART (photo from this website): Dingos! An artist’s rendition of the Fuejian dog (left) and a picture of the cuelpo (right): The cuelpo, happy fox-like canid: A very fancy rat: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. Before we get started, and before I forget again to tell you about this, I’m planning a bonus Q&A episode for August. If you have any questions about the podcast, podcasting in general, me, or anything else, feel free to email me at [email protected], or otherwise contact me through social media! A few episodes ago I mentioned in passing that the Australian dingo is a type of feral dog. It’s a more complicated situation than it sounds, so while I didn’t want to confuse the issue at the time, I kept thinking about it. Then I remembered that a listener emailed me a while back wanting to know more about how dogs were domesticated. We covered the topic pretty thoroughly back in episode 106, but I realized that there’s an aspect of domestication we didn’t cover in that episode. So thanks to “dog freak Ruby,” here’s an episode about a few animals that are only semi-domesticated. Domestication, after all, isn’t a switch you can flip. It’s a process, and depending on the animal species and the circumstances, it can take a really long time. It’s not the same thing as taming an animal, either. An individual animal might become tame with the right treatment, but that doesn’t mean any individual of that species would react the same way. Domesticated animals show genetic changes that their wild counterparts don’t, changes that make them more likely to treat humans as friends instead of potential predators. Generally, a fully domesticated animal requires some level of care from a human to survive, even if it’s just feral cats living near humans so they can find and kill rodents and avoid most predators. Feral domesticated cats don’t live the same way as their wild ancestors do. But sometimes it’s not as cut and dried as it sounds. While mustangs and other feral horse populations are considered domesticated animals, they live like wild animals and don’t need humans to survive. They mostly just need humans to leave them alone so they can thrive on their own. But if you capture a mustang that’s lived its whole life in the wild, with the right treatment it will eventually become tame, because its ancestors were bred for thousands of years to trust and depend on humans. That brings us to our first semi-domesticated animal, the Mongolian horse. Yes, I’m still really into Mongolia and the Hu, and I’m excited to say I have tickets to see the Hu twice in concert this fall, if everything goes well. I’ve been listening to a program called the Voice of Mongolia in English, which is primarily a shortwave radio program but it’s also released as a podcast, and it talks about various aspects of Mongolian culture. Recently they had an episode about horses, so some of my information comes directly from that show. Mongolia is a country in central Asia that’s mostly open steppes, which is a type of grassland. The soil isn’t right for most crops, but it’s great for horses. The people of Mongolia are traditionally nomadic, moving around from place to place to find grazing for their horses and other livestock, and about half of the current population still lives this way. The Mongolian horse is a small, tough breed that probably hasn’t changed much in the last thousand years, possibly longer. It’s one of the oldest breeds of horse in the world and the ancestor of many other horse breeds. For a long time people assumed it was the domesticated descendant of the wild Przewalski’s horse, but genetic testing has determined that domestic horses developed from a different wild horse species that’s extinct now. Genetic testing also showed that the Mongolian horse has the highest genetic diversity of any horse breed tested. It’s incredibly strong for its size, can gallop for miles without tiring, has strong hooves that never need trimming or shoeing, and seldom needs or receives veterinary care. The main reason for all these traits is that Mongolian horses live like wild horses in most ways. They live loose, grazing as they like, and if they get too far away from their humans, the owners will go out to find them. But they’re still domesticated. Mare’s milk is an important part of the Mongolian diet, so the mares are used to being milked, and people use their horses to ride, carry packs, and pull carts. The stallions are frequently raced. At the same time, though, they’re not really pets. Mongols don’t give their horses names, but instead refer to them with a det

Episode 231: Fish of the Twilight Zone

Good thing it’s only a few inches long: An indignant bristlemouth (someone should take MS Paint away from me): The bristlemouth is the most abundant vertebrate in the WORLD (photo by Paul Caiger): Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. Where on earth does the time go? Suddenly we’re halfway through 2021 and I’m still vaguely thinking we’re only a few months in. I’m getting seriously behind on listener suggestions, so let’s have an episode about some weird fish that’s all listener suggestions. Thanks to Page, Joel, an animal lover who wants to remain anonymous, Brigham (whose name I hope I’m pronouncing correctly), and someone who calls themself Fireburster. Fireburster and Anonymous Animal Lover also both left us really nice reviews, so thank you! I picked all these suggestions at random, just grabbing fish suggestions that sounded interesting, but the great thing is they all turned out to live in a specific part of the deep sea. Brigham and Fireburster both suggested the same fish, so let’s start with that one: the dragon fish. Neither of them specified which kind of dragon fish they’re talking about, though. It’s a popular name for weird fish of various kinds. We’ve even talked about a few before, the Pacific blackdragon of episode 193, which was coincidentally suggested by Page, and the barbeled dragonfish in that same episode. That’s the episode about William Beebe’s mystery fish, which happens to be my current favorite. We only talked about the barbeled dragonfish briefly before, so let’s learn more about them now. The barbeled dragonfish gets its name from the filament that hangs down from its chin, called a barbel. If you’ve ever wondered what the proper name for a catfish’s whiskers is, they’re also barbels. The dragonfish’s barbel has a photophore at the end that produces blue-green bioluminescent light, and the fish flashes the light to attract prey. Its head is large and its jaws are full of sharp teeth, so when an animal comes close, CHOMP! The barbeled dragonfish grabs it. The dragonfish isn’t very big, with the blackdragon that we talked about in episode 193 being the largest at only 16 inches long, or 40 cm. Most species are about half that. So what happens when an animal the same size as or even bigger than the dragonfish happens along? The dragonfish eats it, that’s what happens. It has large jaws that it can unhinge to swallow prey that’s bigger than it is, and its stomach can expand considerably to hold whatever it swallows. Mostly it just eats tiny animals like krill and amphipods, though. We don’t know a whole lot about dragonfish. Various species live throughout most of the world’s oceans, especially in tropical and subtropical areas, and they don’t live in the deepest parts of the ocean. Instead, they’re found in what’s called the twilight zone, or more properly the mesopelagic. Only 1% of all light shining down from the surface makes it down this far, which is why so many animals produce their own bioluminescent light. The dragonfish also has photophores along its sides that it can flash to help attract prey or attract mates. On nights when the moon isn’t too bright, the dragonfish will migrate closer to the surface to find more food, but it makes sure to go back to the twilight zone before the sun rises. [twilight zone music] One genus of dragonfish is called the viperfish, and they’re a little different from other dragonfish. Instead of a barbel on the chin, viperfish have a light at the end of a long spine that’s a modified dorsal fin. This is similar to the anglerfish we’ve talked about many times before, even though dragonfish and anglerfish aren’t related. Convergent evolution, at it again! The viperfish has teeth so long they don’t fit in its mouth. Instead, they stick out, which gives it its other name of fangfish. Sloane’s viperfish has the largest teeth of all the viperfish species, so long that they form a cage across its mouth to stop prey from escaping before the fish can swallow it. Unlike most dragonfish, Sloane’s viperfish sometimes swims toward its prey very quickly, slamming into it and wounding it with its fangs. It even has a sort of built-in shock absorber in its spine right behind its head. The Pacific viperfish can

I’m your host, Kate Shaw. A few weeks ago I got to meet two listeners, Brad and Dan. We met for coffee and had a great time talking about animals and podcasting and lots of other things. Dan is a podcaster too, cohost of a great show called “Sure, Jan!” which discusses musical theater in detail with a lot of insight and humor. There’s some language not appropriate for kids, but honestly, any kid who’s so into musical theater that they’re listening to a three-part deep dive into “Everybody’s Talking About Jamie,” they can handle a few bad words. There’s a link in the show notes if you want to check it out. Brad and Dan both gave me topic suggestions, so this is their episode! We’ll start with Brad’s suggestion about strange dog breeds. We actually covered this topic a few years ago in a Patreon episode, so Patreon subscribers may recognize a lot of this information, but I’ve done some additional research and added to it. There are a lot more dog breeds out there than most people know, many of them very rare and restricted to particular regions of the world. Often they were bred for specific purposes, sometimes purposes that no longer exist. This is the case for the turnspit dog. It was a short-legged dog that was bred to run on what was called a dog wheel. The dog wheel looked like a big hamster wheel and turned the spit, a metal rod suspended over the fire that a big piece of meat was stuck onto. The dog ran in the wheel, which turned it, which turned the cord attached to the spit, which turned the spit, which meant the meat cooked evenly instead of staying raw on one side and burning on the other. Usually a household had two turnspit dogs so one could rest while the other took a turn running in the wheel. Once better technology was invented to cook meat, the turnspit dogs were out of a job and eventually stopped being bred. They’re now an extinct breed. Another extinct dog breed is the Talbot hound. It was a large, relatively slow and heavy hound with white or pale-colored fur, popular in Europe for hundreds of years as a hunting dog. It appears on many coats of arms. It was less of a breed than a type of dog, with many large hounds being referred to as talbots as far back as the 15th century and Talbot being a common name for a hound in the 14th century and possibly earlier. By the 17th century it was more of a standardized breed, resembling a white or light-colored bloodhound in appearance with a tail that curled upward. But by the 19th century it had gone extinct. It might have been the ancestor of the modern beagle. Many dog breeds aren’t all that old, only dating back to roughly the early 19th century. In the Victorian era in Britain, people got really interested in recreating dog breeds from antiquity, so some breeds that people think date back to antiquity were actually developed just a few hundred years ago. But there are some breeds that genuinely have been around and more or less unchanged for a really long time. The Xoloitzcuintli (sho-lo-eets-quint-lee) or Xolo is a rare breed of dog that was originally bred by the Aztecs and dates back more than 3,500 years. It’s a hairless dog, although many actually do have a full coat. The hairless variety has black or gray-blue skin that is susceptible to sunburn, while the coated variety has short, dense hair. Because hairlessness is genetically related to a condition where not all the teeth form, hairless Xolos usually have fewer teeth than coated Xolos. Hairless dogs need sunscreen and skin care to keep their skin healthy just like people do. Another old dog breed is the Norwegian Lundehund. It’s a small, active dog bred specifically for hunting puffins. The breed nearly went extinct after a dog tax made it hard for people to afford keeping numerous dogs, and instead they started using nets to hunt puffins. After the puffin was declared a protected species, even the people who still kept lundehunds for hunting stopped breeding them. By 1963 there were only six purebred lundehunds alive, five of them related to each other. As a result, despite careful breeding guidelines, modern lundehunds are extremely inbred and prone to genetic diseases. Currently a group of breeders and geneticists are working on crossbreeding the Lundehund

I’m your host, Kate Shaw. It’s been an amazing week for me because I got to take some people to see our local synchronous fireflies! The fireflies put on a brilliant show for us and the weather was perfect, and it was so much fun to meet Shannon and Diana! Then, two nights later, I also took Derek and Autumn out to see the fireflies. In between, I started research on the blue ghost firefly, since I had originally thought it was just another name for the synchronous firefly, but it’s not. So this week we’re going to learn about the blue ghost firefly, along with some interesting breaking news about a shark mystery. The blue ghost firefly only lives in parts of the eastern and central United States. In most places it’s rare, but like the synchronous fireflies that all flash together, the blue ghost fireflies are actually pretty common in the southern Appalachian Mountains. The reason why people don’t see them more often is that these days, most people don’t spend much time in the woods at night. Like other fireflies, the blue ghost lives in forests with deep leaf litter where there’s a lot of moisture in the ground. The female lays her eggs in the leaf litter and when the eggs hatch, the larval fireflies eat tiny insects and other invertebrates like snails. The blue ghost firefly is different from other firefly species in several ways. First, it doesn’t flash. The male stays lighted up for around a minute at a time while he flies low over the ground watching for a female to light up too. Its glow also appears bluish-white to human eyes, at least in the distance and when it’s really dark out. Up close, it looks yellow-green like other firefly lights. Researchers think it only looks blue because of the way human eyes perceive color in low light. In the daytime, blue ghost fireflies don’t look like much. They’re small, around 7 mm long, and males are all brown. The females don’t have wings, and in fact they never metamorphose into the adult form and still look like larvae as adults. The female crawls to the end of a twig or blade of grass and glows to attract a mate. When I was doing my research to learn about blue ghost fireflies, I kept seeing articles comparing its size to a grain of rice. I looked up the average size of a grain of rice, and that’s where I got 7 mm. I didn’t think too much about it. When Shannon, Diana, and I were watching the synchronous fireflies, we noticed some fireflies that didn’t flash, just stayed glowing while they drifted along low over the forest floor. After I started researching blue ghost fireflies, I realized that was what had seen! So I was especially excited to go back out with Derek and Autumn and confirm it. Derek works for a nonprofit that breeds endangered fish for conservation projects, which is awesome, but he’s also a photographer, so he brought his camera to try and get pictures and video of the fireflies. His photographs are amazing so if you want to see them I’ve linked to his Facebook page, EnchantingEctotherms, in the show notes. He does a lot of snorkeling so a lot of the animals he photographs are fish or other water animals like turtles and snakes, and he gives information about them in his posts. Anyway, he wanted to get close-up pictures of a synchronous firefly and a blue ghost firefly, so we all spent some time trying to catch one of each—gently, of course, and without leaving the trail. We didn’t want to hurt ourselves in the dark or disturb the fireflies’ habitat. Derek caught a synchronous firefly first, and it looks like an ordinary firefly that I’m used to, the common eastern firefly, which grows to about 14 mm long. That’s half an inch long. Then, eventually, he also caught a blue ghost. It was so small that at first we thought he might have caught some other beetle by accident, until we looked more closely and saw the telltale head shape of a lightning bug. I took a photo myself and put it in the show notes so you can see just how small it is. From my own observation, the blue ghosts are much dimmer than other fireflies, which makes sense since they’re so much smaller. The light does look

Sign up for our mailing list! We have a merch store now too! Thanks to Ethan for this week’s topic, two weird animals that developed after the Great Dying we talked about last week! Further reading: Monkey Lizards of the Triassic Placodonts: The Bizarre ‘Walrus-Turtles’ of the Triassic Drepanosaurus (without a head since we haven’t found a skull yet, but with that massive front claw): Drepanosaurus’s tail claw: Hypuronector had a leaf-like tail: Placodus was a big round-bodied swimmer: Some placodonts [art by Darren Naish, found at the second article linked above]: Henodus was the oddball placodont that probably ate plant material: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.   Last week we talked about the end-Permian mass extinction, also called the Great Dying. This week let’s follow up with a couple of weird and interesting animals that evolved once things got back to normal on Earth. Thanks to Ethan who suggested both animals.   The great dying marks the end of the Permian and the beginning of the Triassic period, which lasted from about 251 million years ago to 201 million years ago. In those 50 million years, life rebounded rapidly and many animals evolved that we’re familiar with today. But some animals from the Triassic are ones you’ve probably never heard of.   We’ll start with a reptile called the drepanosaur. Drepranosaurs are also sometimes called monkey lizards for reasons that will soon become clear. Paleontologists only discovered the first drepanosaur in 1980, Drepanosaurus, and within a few years they recognized a whole new family, Drepanosauridae, to fit that first discovery and subsequent closely related specimens. Drepanosaurs were weird little reptiles that probably looked like lizards in many ways, although they weren’t lizards.   How weird was Drepanosaurus? Very weird. Very, very weird.   It was obviously a climbing animal that probably spent all of its life in the treetops. It had lots of adaptations to life in trees, such as hind feet where all the toes pointed in the same direction and were somewhat curved, sort of like a spider monkey’s hand. That would help it get a good grip on branches. But those hind feet aren’t why it’s called the monkey lizard.   Drepanosaurus and its relatives are called monkey lizards because of their tails. Many monkeys have prehensile tails, which act as a fifth limb and help keep the monkey stable in a tree by curling around branches and hanging on. Drepanosaurus had something similar. Instead of being mobile from side to side like most reptile tails, Drepanosaurus’s tail could mostly only curve downward. Modern chameleons have an even more pronounced downward-curving tail that helps them climb. But the chameleon’s tail is still just a tail. The end of Drepanosaurus’s tail had several modified caudal bones that were probably exposed through the skin. Those modified bones acted as a claw to help the animal grab onto tree trunks and branches. So Drepanosaurus had claws on its front feet, claws on its hind feet, and a claw on its tail. It’s sort of like having five feet.   As if that wasn’t weird enough, let’s talk about those claws on the front feet. It had five toes on each foot, and four of them had ordinary claws. They were sharp but fairly small, about what you’d expect from an animal that grew about 19 inches long at most, or 50 cm. But the second toe on each foot, which corresponds to the pointer finger on a human hand, had a much bigger claw. MUCH BIGGER CLAW. It was as big as its whole hand! Most researchers think it used the claw to dig into rotting wood, insect nests, and bark to find insects and other small animals to eat.   But that’s not all. Drepanosaurus also had a structure called a supraneural bone at the base of its neck, made up of fused vertebrae, that would have made it look like it had a little hunch on its shoulders. While we don’t have a skull of Drepanosaurus, since we only have three specimens so far, this structure is also present in other drepanosaur species where we do have the neck and head, and they all have fairly long, slender necks and birdlike skulls with large eyes. It’s possible that the supraneural bone was the attachment site for special muscles that helped Drepanosaurus extend its neck very quickly to grab insects and other small animals.   Drepanosaurs in general shared many of the traits seen in Drepanosaurus, although with some differences. Many drepanosaurs had opposing toes on the feet that would help them grasp branches and twigs more securely. Most don’t have the giant claw on the front feet although most do have the tail claw. But one monkey lizard doesn’t live up to its name at all.   A little drepanosaur called Hypuronector limnaios, which only grew about five inches long, or 12 cm, had a much different tail from its relations. Its tail didn’t curve downward at all—in fact, it stuck up behind

I’m your host, Kate Shaw. It’s time for our next extinction event episode, and this week it’s the big one. Not the extinction event that killed the dinosaurs, but one you may not have heard of, one that almost destroyed all life on earth. I mean, obviously it didn’t and things are fine now, but it was touch and go there for a while. It’s the Permian-Triassic extinction event, or end-Permian, which took place just over 250 million years ago. It was so bad that scientists who aren’t given to hyperbole refer to it as the Great Dying. Don’t worry, we won’t talk about extinction the whole time. We’ll also learn about some interesting animals that survived the extinction event and did just fine afterwards. We have a better idea of what happened at the end of the Permian than we have about the earlier extinction events we talked about in episodes 205 and 214. Right about 252 million years ago, something caused a massive volcanic eruptive event in what is now Siberia. Some researchers speculate that the cause of the volcanic eruptions may have been a huge asteroid impact on the other side of the Earth, which was so powerful that it caused magma to move away from the impact like water sloshing in a jostled glass. The magma rose up toward the earth’s crust and eventually through it onto the surface. The result was probably the largest volcanic event in the last half-billion years and it continued for an estimated two million years. Most of the eruptions were probably pretty low-key, just runny lava pouring out of vents in the ground, but there was just so much of it. Lava covered almost a million square miles of land, or 2.6 million square km. Ash and toxic gases from some eruptions also ended up high in the atmosphere, but one big problem was that the lava poured through sediments full of organic material in the process of turning into coal. Lava, of course, is molten rock and it’s incredibly hot. It’s certainly hot enough to burn a bunch of young coal beds, which added more ash and toxic gases to the air—so much ash that shallow water throughout the entire world became choked with ash. The carbon dioxide released by all that burning coal caused severe ocean acidification and ocean anoxia—a lack of oxygen in the water. But it gets worse! A lot of lava erupted into the ocean right at the continental shelf, where the shallow coastal water becomes much deeper. This is exactly the place where you find methane deposits in the sediments on the ocean floor. When those deposits were suddenly disturbed by lava flowing into them, all the methane in the formerly tranquil depths was released and bubbled to the surface. Methane is a powerful greenhouse gas, meaning that if a whole lot of it ends up in the atmosphere in a short amount of time, it can cause rapid global warming—much faster than that caused by carbon dioxide. This global warming would have happened after a period of global cooling due to reduced sunlight reaching the earth through ash clouds, which lasted long enough and was severe enough that sea levels dropped as glaciers formed. Then everything heated way, way up. The ice caps melted, which may have led to a stagnation of ocean currents. This in turn would have contributed to the water’s anoxicity and toxicity. The average temperature of the ocean would have increased by almost 15 degrees Fahrenheit, or 8 degrees Celsius. Atmospheric warming may have been as much as 68 degrees Fahrenheit in places, or 20 degrees Celsius. That’s not the average temperature of the world, that’s the temperature increase. So, basically, everything was terrible and it happened very quickly in geologic terms. A 2018 study found that everything looked pretty much fine for the 30,000 years leading up to the great dying. Some researchers even think the initial extinction event might have taken place over just a few centuries. Marine animals were affected the most, especially marine invertebrates. Trilobites and placoderms went extinct, eurypterids went extinct, and corals went extinct until about 14 million years later when modern corals developed. Some researchers estimate that 95% of all marine species went extinct. Things were better on land, but not that much better. At the end of the Permian, life was good on land and it was especially good for insects because of the high percentage of oxygen in the air and the variety of plant life in huge swamps around the supercontinent Pangaea. The largest insects that ever lived were buzzing around in the P

Episode 226: Brood X Cicadas

Sign up for our mailing list! It’s the 2021 brood of 17-year cicadas! Thanks to Enzo (and several others) who suggested it! Further listening: Varmints! Podcast – “Cicadas” Our local Brood X cicada (photo by me!): The holes that cicadas emerged from (photo also by me): Discarded cicada shells. My work keys and Homestar Runner keychain for scale: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This week we’re going to talk about cicadas, specifically the 17-year cicadas that you may have heard about in the news or in your own back yard, depending on where you live. Thanks to the several people who suggested the topic on Twitter, with special thanks to Enzo who emailed me about it. I actually wasn’t going to do a cicadas episode because we already talked about cicadas way back in episode 28. We didn’t go into too much detail in that one, but Varmints! podcast did a great in-depth show about cicadas recently so I’ve been referring people to them, and check the show notes for a link if you don’t already listen to Varmints. Besides, I hadn’t heard any of the cicadas myself so I didn’t see what the big deal was. Then I returned to work after taking some time off to take care of my cat Poe, who by the way is doing really well now and thanks for all the well wishes! The second I got out of my car, I heard them. The cicadas. Now, we get cicadas every year where I live in East Tennessee, so the sound is familiar to me and I actually like it. I find it soothing and the quintessential sound of summer. But this was something else. At only 8am the trees along the edge of campus were filled with what I can only describe as a high-pitched roar. I went out at lunch and the sound was even louder. I got some audio, so here’s what a whole bunch of cicadas sound like when they’re calling at once. [cicada sounds] I also got pictures, which you can see in the show notes. The cicadas emerging in such numbers this year are 17-year cicadas. They spend almost all of those 17 years as nymphs underground, where they eat sap from the roots of trees and other plants. At the end of the 17 years, when the soil is warm enough, they emerge from the ground and molt into their final form, the full-grown adult cicada! The adult cicadas have wings but aren’t very good fliers. I can definitely attest to that because when I was taking pictures of them, I kept having to dodge as cicadas flew from bush to tree and either didn’t see me standing there or thought I was a weird tree or maybe just couldn’t maneuver well enough to avoid me. They’re pretty big insects, up to two inches long, or five cm, with gray or black bodies and orangey-red legs and eyes. The wings have pale orange veins. The first cicadas to emerge are mostly males, in such numbers that predators get too full to care when the females emerge a few days later. That way more females survive to lay eggs. At first the cicadas that emerge still look like nymphs, but within about an hour they molt their exoskeleton and emerge as full adults with wings. They’re pale in color until the new exoskeleton hardens and the wings expand to full size, which takes a few days. This, of course, leaves behind a cicada shell, which is the shed exoskeleton. When I was very small, I was terrified of cicada shells even though they’re just empty and perfectly harmless. They look scary because of those big pointy legs and big round eyes. You can frequently find cicada shells still stuck to tree bark, and it’s okay to pick them up and collect them if you like. The cicada doesn’t need it anymore. You can see the slit along the back of the shell where the cicada climbed out. The emerged cicadas climb or fly into trees where the males start singing. Males produce their loud songs with a structure called a tymbal organ in their abdomen. The abdomen is mostly hollow, which helps amplify the rapid clicking of a pair of circular membranes. The clicking is so fast, up to 480 times a second, that humans hear it as a continuous buzzing noise and not individual clicks. Some cicada songs are louder than 120 decibels, which is the same decibel level as a chainsaw. A reminder: this is what they sound like: [more cicada sounds] A female finds a male by listening to his song. After a pair mates, the female makes little cuts in twigs at the end of a tree branch, usually new-growth twigs because they’re softer. She lays her eggs in the cuts, then soon dies and falls to the ground. Within a few weeks, all the adult cicadas have died. But around eight weeks later, the eggs hatch. The new nymphs are teensy, only a few millimeters long. They drop to the ground and burrow into the soil up to a foot deep, or 30 cm. There they stay for the next 17 years, growing larger very slowly until it’s time to emerge. The current big group of cicadas consists of three species that look very similar. It’s called brood ten although I agree with Varmints who think it should be brood X because the

I’ve linked to the mailing list in the show notes, and it’s also linked on the website and my social media, but if you can’t find it, just send me a message and I’ll reply with the link. The final announcement is that my cat Poe is finally home and recovering from a scary illness. He developed what’s called pyothorax, which is an infection in the chest, and in Poe’s case we still don’t know what caused it. After a week in the veterinary intensive care unit, he’s finally home and getting better all the time. That’s why last week’s episode was so short, and if you messaged me this week about something and I seemed impatient when I replied, that’s why. I just haven’t had any mental energy to concentrate on anything but Poe. Thank you to everyone at the Animal Emergency and Specialty Center of Knoxville for taking such good care of him. We’ve got something fun and a little different this time, inspired by two things. First, I saw a tweet about a captive beluga whale who had apparently learned to mimic human speech and one night told a diver in his pool to get out. Then the awesome podcast BewilderBeasts had a segment about a harbor seal in Maine who was rescued by a fisherman as a pup, which reminded me of a similar situation with another harbor seal in Maine, Hoover the Talking Seal. That’s right, it’s an episode about mammals that can talk, including one of my favorite cryptozoological mysteries ever. Before we learn about talking animals, we need to learn a little bit about how humans talk. Humans produce most vocal sounds using our larynx, which is sometimes called a voicebox. The human larynx is situated at the top of the throat, and it helps us breathe, helps keep food from going down the wrong tube and into the lungs, and enables us to make sounds. It consists of cartilage, small muscles, and flaps of tissue called vocal folds or vocal cords. There are two kinds of vocal folds: the true vocal folds that are connected to muscles and actually produce sound, and the false vocal folds that don’t have any connected muscles and just help with resonance. Usually resonance just makes the sound louder, but humans have learned to do amazing things with our voices. Some cultures use the false vocal folds to create a secondary tone. It’s called overtone singing, throat singing, or harmonic singing. I’m still completely in love with the Mongolian folk metal band the Hu and am now delighted that I can mention them again, because they use throat singing in their music. Throat singing produces overtones with various different sounds, depending on the technique used, but it can be hard to pick them out of a song if you’re not sure what you’re hearing. So instead of playing a clip of a Hu song, here’s a clip of a musician demonstrating various kinds of throat singing while also playing along on the morin khuur, or horsehead fiddle. The morin khuur only has two strings so the drone and whistle sounds you’re hearing are not from that instrument, they’re made by the musician’s voice. [Musician is Zagd Ochir AKA Sumiyabazar.] [clip of throat singing] When you think of animals that could potentially talk in human language, naturally you’d assume our closest relatives, the great apes, could learn to talk. But while apes have larynxes that are similar to ours, they don’t have the fine control over their vo

Episode 224: Diprotodon and Friends

Thanks to Ruby and Tex for their suggestions this week! Diprotodon was big and had a big nose: Koala! The bush thick-knee looks like it has regular knees, actually: Show Transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This week let’s head to Australia for a short episode about three interesting animals. Thanks to Ruby and Tex for their suggestions! Recently, we had an episode about the wombat—episode 208, to be exact. Ruby suggested we talk about an extinct giant wombat called Diprotodon too, because while we touched on it in the wombat episode, an animal that awesome deserves more attention. Also, Ruby had just gone to the Australian Museum and learned about it, and naturally wanted to share that knowledge. So let’s find out more about Diprotodon! Diprotodon was the largest marsupial ever known. It stood around 6 ½ feet tall at the shoulder, or two meters, and up to 12 feet long, or 4 meters. It was related to the wombat but probably didn’t look much like one, although I bet it was pretty cute. It was heavily built and its legs were pillar-like, similar to a rhinoceros’s legs, but its feet were actually kind of small in comparison. It had massive flat front teeth and long claws. So did those big teeth and claws mean it ate meat? Nope, it was a plant-eater, just like the wombat. It ate plants of all kinds in the savannas and plains where it lived, and its teeth were adapted to shear through branches and roots like chisels and grind up plant material at the same time. It also did a lot of digging, which is what it used its long claws for. The female had a rear-facing pouch so dirt wouldn’t get on her joey while she was digging. Diprotodon had a larger nasal aperture in its skull than would be expected for an animal its size. It probably just had a really big nose, but some researchers think it might actually have had a short trunk sort of like a tapir’s. Diprotodon probably lived in small groups made up of related females and their babies, while males probably spent most of their time either solitary or in small bachelor groups. It may have been migratory too. It went extinct somewhere between 42,000 and 25,000 years ago, along with many other species of Australian megafauna. Researchers think climate change was probably the main cause of its extinction, as the climate where it lived became drier. Diprotodon was also related to the modern koala. We talked about the koala in episode 94, but Tex wanted to know more about it. In episode 94 we learned that the koala smells like a cough drop because of all the eucalyptus leaves it eats. Eucalyptus oil is a common ingredient in cough drops. Here’s some other basic information about the koala from that episode, and then we’ll go on to learn something new about it. The koala is a marsupial that lives near the coasts of eastern and southern Australia in eucalyptus trees, also called gum trees. It’s gray, gray-brown, or brown in color, with no tail, short floofy ears, a flat face with a big black nose, and long claws that help it cling to tree trunks. Almost its entire diet is made up of eucalyptus leaves, which are toxic, but the koala’s liver produces a type of protein that breaks down the toxins so it doesn’t get sick. It spends almost its whole life in trees except when it needs to move from one tree to another one. In a study published in May 2020, researchers finally figured out how the koala gets water. Until this study, everyone assumed that the koala usually got enough moisture from the leaves it eats that it didn’t need to drink water most of the time. Now, though, researchers have observed koalas licking water from tree trunks during rain. This makes sense, because koalas prefer to stay in a tree whenever possible. The study determined that the koala gets about three-quarters of the moisture it needs from leaves, and during droughts it will come down from its tree to drink from streams. But in ordinary circumstances, it licks water from the tree trunks during and just after rain, and will do so even when other water sources are available. I bet if you called someone a tree-licker, they would think it’s an insult, but really it’s adorable. You can say, “You’re such a tree-licker” to someone, and if they get mad at you, you can explain about koalas, hopefully before they hit you. Let’s finish this short episode with a type of bird. It’s called the bush thick-knee. It’s nocturnal and while it can fly, it spends most of its time walking along the ground looking for small animals to eat. It’s a large, slender bird with a wingspan over three feet across, or one meter, and long legs. The bush thick-knee eats frogs, lizard, small snakes, small mammals, crustaceans and mollusks, and insects and spiders. It will sometimes eat seeds or other plant material too. During the day it hides in long grass where it’s hidden from predators and has some shade, and at night it comes out and walks around. It’s especially active on moonlit nights. And dur

Episode 223: The Elephantnose Fish and the Burmese Star Tortoise

Sign up for our mailing list! This week let’s learn about an amazing little fish and an awesome tortoise! All the pictures here were taken by ME at the Tennessee Aquarium in Chattanooga! Further Reading: Star tortoise makes meteoric comeback The astonishing elephantnose fish: Burmese star tortoises: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. I’m fully vaccinated now so I’m able to go out and about cautiously, still wearing a mask of course, and this weekend I went to the Tennessee Aquarium in Chattanooga. I had a fantastic time and saw lots and lots of amazing fish and other animals! If you ever get a chance to visit, it’s definitely worth it. When I got home, I kept thinking about one particular fish. I wanted to learn more about it. So I decided to make an episode about that fish and another animal I saw at the aquarium. The fish that captivated me so much is called the elephantnose fish. I’d never seen anything like it. The one I saw was about the length of my hand, dark gray or black in color, and looked like a pretty ordinary fish except for the proboscis that gives it its name. The fish has a flexible projection from its nose that it was using to probe around in the gravel at the bottom of its river habitat. I should mention that the Tennessee Aquarium has enormous displays, beautifully designed to mimic the animals’ natural habitat and give them plenty of room to move around. There’s one tidal animals display in the ocean side of the aquarium where the water sloshes through and around rocks to mimic the tide. It’s fascinating to watch the fish in that exhibit stay pretty much motionless despite the water’s movement, because that’s what they’re adapted for. So there’s plenty of opportunities to see an animal’s behavior. Anyway, I took lots of pictures of the elephantnose fish and when I got home, I started researching it. It turns out that it’s way more interesting even than I thought! It lives in rivers and other freshwater in central Africa and grows up to 9 inches long, or 23 cm. That’s according to the info display next to the exhibit. The display also said the fish was a species called Peter’s elephantnose fish, although it’s possible they have more than one species on display. There are a lot of elephantnose fish, more properly called mormyrids or freshwater elephantfish, and many of them have this interesting proboscis. The proboscis isn’t actually a nose like an elephant’s trunk. It’s technically a modified chin and mouth, called the Schnauzenorgan. The elephantnose fish mostly eats small worms and insect larvae, and it especially loves mosquito larvae. The elephantnose fish uses electroreception to navigate the muddy waters where it lives and find food. Its whole body, and especially its Schnauzenorgan, is covered with electrocyte cells that can detect tiny electrical pulses. If you remember way back in episode ten, about electric animals, many animals can sense the weak bioelectrical fields that other animals generate in their nerves and muscles. It’s especially common in fish since water conducts electricity much better than air does. But the elephantnose fish also generates a stronger electric field of its own, which it uses as a sort of sonar. It generates the field in special electric organs in its tail, and as it moves around in the water, the electric field comes in contact with other things—plants, rocks, other fish, and so on. It’s not strong enough to give an animal a shock, but it’s strong enough for the elephantnose fish to easily sense changes in its environment. The fish can tell what it’s near because its electrical field interacts differently with different things. A rock, for instance, doesn’t conduct electricity so the fish probably senses it as a blank spot in its electrical field, while a plant may conduct electricity even better than water and therefore changes the shape of the fish’s electrical field in a particular way. But it doesn’t generate its bioelectric field all the time. It can control when it discharges pulses of electricity the same way a dolphin can control when it sends out pulses of sound. If the fish feels threatened, maybe by another elephantnose fish nosing in on its territory, it will pulse much faster so it can keep tabs on what the other fish is doing—plus, of course, the other elephantnose fish can sense its pulses and can interpret how aggressive the first fish is. Female elephantnose fish generate a slightly different electrical field than males, which allows males and females to find each other to spawn. You may be thinking about all this and wondering how the elephantnose fish can sense the tiny bioelectric charges of its tiny prey over its own electric field. Its electric field is much stronger than that of a teensy worm hiding in the mud, after all. It would be like trying to hear a bird chirping outside through a closed window while someone is playing music really loudly in the room you’re in. It turns

I’m your host, Kate Shaw. It’s time to revisit New Guinea and its weird and amazing birds! This week we’re going to look at two dangerous birds of New Guinea. Thanks again to M Is for Awesome for the suggestion. Lots of birds are pretty or cute, and that’s great. But some birds…are dangerous. For instance, the cassowary. There are three species alive today, all of which live in New Guinea along with some other nearby islands. The southern cassowary lives in northeastern Australia too. It’s a big, shy, flightless bird that lives deep in the rainforest. The biggest species is the southern cassowary, which can grow up to six and a half feet tall, or 2 meters. Its wings are small but it can run extremely fast, up to 30 mph, or 50 km/h. It can also jump and even swim extremely well. This is surprising not just because it’s such a big bird but because it looks ungainly. It’s shaped sort of like its relation, the emu, although its neck is shorter, with a big chunky body, long strong legs, and a little head in comparison. Females are larger than males on average with more brightly colored necks. The cassowary’s body is covered with black feathers while the legs are bare, as is the neck and head. The neck is bright blue in females, paler blue in males, with red wattles that hang down as decoration. The face is a lighter blue with a black bill. It has spine-like feathers that grow from its small wings, which appear to be for decoration too, or at least the cassowary doesn’t seem to use those spiny feathers for anything. But the most unusual thing about the cassowary is the casque on its head. The casque is a sort of plate that grows on the top of the bird’s head. Different species of cassowary have different shaped casques, and there’s some variation in size and shape of casques from individual to individual. The dwarf cassowary is the smallest, naturally, and has a relatively low casque. The northern cassowary has a larger, taller casque and the southern cassowary has the largest, tallest casque, shaped sort of like your hand if you keep it flat with all your fingers together, only instead of flat it’s sticking up from the top of the bird’s head. Looking at a cassowary is like looking at a dinosaur with a beak. The casque consists of a bony core made up of two layers around an open space, and it’s covered with a keratin sheath. This is similar in structure to the kind of horns many hoofed animals have, like cattle and sheep, but there are plenty of differences. The sheath isn’t as hard as the keratin sheath on a mammal’s horn, for one thing. It’s actually a little bit leathery. It also contains a pocket inside the skull beneath the casque that’s full of delicate tissue made up mostly of tiny blood vessels. No one except the cassowary knows for sure what the casque is for. Over the years, researchers have suggested it might be used as a weapon, it might act as a shield to keep falling fruit from injuring its head when it’s under a fruit tree, it might knock the casque against a tree to make fruit fall, it might use it to dig with, it might use the empty space inside as a resonant chamber to make noise with, or it might use the empty space inside to help it hear faint sounds. Most likely, the casque is primarily for display. Since the cassowary does communicate with low-frequency booming sounds to attract mates, it might also help with resonance or amplification of its calls. The cassowary mostly eats fruit, which it swallows whole, even large fruit like apples. This is good for the plants, since it poops out seeds which are then ready to sprout in their own little pile of fresh fertilizer. It will also eat flowers and other plant material, but if it can catch a frog or mouse, or other small animal, including insects and snails, it will eat them too. It even sometimes eats carrion. A female’s territory overlaps that of several males, and she seems to form a bond with all of them. In breeding season she makes deep, booming calls, which a male answers with a running dance. The female often chases the male into water and follows him in, where he then chases her out of the water before they mate. Then the male builds a nest on the ground, basically just a pile of grass and leaves, and the female lays her eggs in the nest. The male takes care of the eggs and the chicks when they hatch. Meanwhile, the female leaves and finds one of the

Episode 221: Arachnids in the Antarctic!

Thanks to Ella for this week’s suggestion. There may not technically be spiders in the Antarctic, but there are mites. A nunatak (note the size of the research vehicles at the bottom left): I don’t have any pictures of the Antarctic mites, so here are some red velvet mites, although they’re giants compared to their Antarctic cousins: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This week we’re going to have a short episode, because I get my second Covid-19 vaccine on the Thursday before this episode goes live and I want to have the episode all finished before then. That way if I feel bad afterwards I can rest. Thanks to Ella for this week’s suggestion! Back in episode 90, about some mystery spiders, I mentioned that spiders live everywhere in the world except Antarctica. Well, guess what. Ella sent me some links about spiders that live in…Antarctica! Antarctica is a landmass at the South Pole, specifically a continent about twice the size of Australia. It looks bigger than it really is because ice projects out from the land and is only supported by water, called an ice shelf. It’s not a little bit of ice, either. It’s over a mile thick, or nearly 2 km. The ice is called the Antarctic ice sheet and it covers 98% of the continent. The only places not covered in ice are some rock outcroppings and a few valleys, called dry valleys because they basically get no precipitation, not even snow and certainly not rain. Researchers estimate that it hasn’t rained in these dry valleys in almost two million years. There are no plants, just gravel. There are no animals but some bacterial life that live inside rocks and under at least one glacier. Scientists have used these dry valleys to test equipment designed for Mars. This is not a hospitable land. Everything that lives in Antarctica is considered an extremophile. That doesn’t mean there’s no life in Antarctica, though, just that it’s only found in a few places, mostly along the coast or on nearby islands. Emperor penguins and Adelie penguins, several species of seal, and some sea birds live at least part of their lives in and around Antarctica, as do some whales. There are lichens, algae, and a few low-growing plants like liverwort and moss. And there are some invertebrates, although not very many and not large at all. The largest is a flightless midge that only grows 6 mm long. But what we’re interested in today are mites found only in Antarctica. We talked about mites in episode 186 when we learned about the red velvet mite. Mites are arachnids, although they’re not technically spiders, but frankly we’re just quibbling at this point. It has eight legs and is in the class Arachnida, so I say there are spiders in Antarctica. Or close enough. There are 30 species of mite in Antarctica. They mostly live on islands throughout the Antarctic peninsula, which sticks out from one side of the continent like a tail pointing at the very tip of South America. All the mites eat moss, algae, and decomposing lichens. They’re also teeny-tiny, less than a millimeter long. One type of mite is found on the mainland of East Antarctica instead of just on islands. It’s called Maudheimia and it only lives on big rock outcroppings that stick up through the ice. These rocks are called nunataks and are covered with lichens. But nunataks are far apart, sometimes hundreds of miles apart, and the mites are so tiny they’re just about microscopic. How did they get from one nunatak to the next? To find out, we have to learn some history about Antarctica. It hasn’t always been at the South Pole. It was once part of the supercontinent Gondwana, and 500 million years ago it was right smack on the equator. You know, tropical. As the centuries passed and the continents continued their slow, constant dance around the Earth, Gondwana drifted southward and broke apart. Antarctica was still connected to Australia on one side and South America on the other, and was still subtropical. Then it broke off from Australia around 40 million years ago, drifted farther southward, and ultimately, about 25 million years ago, separated from South America. Ever since it’s been isolated at the South Pole, and by 15 million years ago it was ice-covered. Fossils of dinosaurs and other ancient animals have been discovered in Antarctica, but it’s hard to find fossils and excavate them when the ground is under a mile of ice. The animals and plants that once lived in Antarctica went extinct gradually as its climate became less and less hospitable, and most of the remaining holdouts went extinct when the ice age began and the continent’s climate was even colder and harsher than it is now. But one animal remains, toughing it out on rock outcroppings where the temperature can drop to -31 degrees Fahrenheit, or -35 Celsius. Maudheimia, the brave little mite. Maudheimia was probably common throughout Antarctica’s mountains before the big freeze happened, and would have already been

Episode 220: Panda Mysteries, Solved!

This week let’s learn about a mystery panda and a few small panda mysteries! Join our mailing list! Further Reading: Mystery of the brown giant panda deepens The Qinling panda is not like other pandas: The giant panda is subtly different from the Qinling panda. Can you spot the difference? Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. I usually like to shake things up from week to week, but April has turned into mammal month. We’ve got another interesting mammal this week, a panda that until recently was a mystery. But first! A quick correction from last week. Pranav emailed to let me know that I got infrasound and ultrasound mixed up. Tarsiers communicate and hear in ultrasound. Infrasound is below human hearing while ultrasound is above. We’ve talked about the giant panda before in episodes 42 and 109. Pretty much everyone is familiar with the panda because it looks so cuddly. It’s a bear, but unlike every other bear it eats plants. Specifically, it eats bamboo, although it will also sometimes eat bird eggs and small animals. It’s mostly white but its ears are black, it has black patches around and just under its eyes, and its legs are black. It also has a strip of black around its body at about its shoulders. But what if I told you there was another kind of panda that wasn’t black and white? I’m not talking about the red panda, which is not actually very closely related to bears. I’m talking about the Qinling panda. Qinling refers to the Qinling Mountains in central China, which is where the pandas live. There aren’t many of them, although to be fair there aren’t many pandas in the wild at all. Estimates vary from around 200 to 300 Qinling pandas in the wild. They live in two big nature reserves, and there’s only one in captivity. The reason you’ve probably never heard of the Qinling panda is because until 2005, no one realized it wasn’t a regular panda with slightly different color fur. In 2005 a genetic study determined that the Qinling panda has been isolated from other pandas for at least 12,000 years and is different enough that it’s considered a subspecies of panda. The Qinling panda is sometimes called the brown panda or sepia panda, because instead of being black and white, it’s brown and brownish-white. Where an ordinary panda has white fur, the Qinling panda has light tan or light brown fur. Where an ordinary panda has black fur, the Qinling panda has brown fur. It’s not dark brownish-black, just a medium brown. It also has a smaller, rounder head than other pandas. In 1989, before anyone realized the Qinling panda was a different subspecies, a female was captured as a mate for a captive giant panda. The pair had a baby who looked like an ordinary black and white panda cub, at least for the first four months of his life. At four months old his fur started to look more and more brown, until he was a brown and pale brown panda instead of a black and white panda. Unfortunately, the baby didn’t survive to grow up, and the mother panda died in 2000. The Qinling panda lives in high elevations and eats bamboo, just like other pandas. Because there are so few of them, and because they’re hard to keep in captivity and hard to find in the wild, we still don’t know a whole lot about them. We do know that the Qinling panda tends to have more tooth problems than regular pandas, sometimes losing its teeth or just fracturing them. This may be due to inbreeding, but it may be genetic. The Qinling panda’s genetic profile indicates that it has more traits in common with the ancestor it shares with giant pandas than the giant panda does. In the time that the populations have been separate, the giant panda has evolved more quickly than the Qinling panda. The giant panda’s teeth may be better adapted to its diet than the Qinling panda’s teeth are. Now that I’ve told you that the Qinling panda has a different color coat than giant pandas, let me back that up a little. Not all Qinling pandas have brown fur. Most are black and white, although they may have a brown tinge to the coat. The brown pandas were first noticed in the 1960s and researchers worry that it’s a sign of inbreeding. Then again, the genetic studies done on Qinling pandas show a healthy amount of genetic diversity with little sign of inbreeding. The brown coloration might be due to other factors. While we’re talking about panda coloration, why does the giant panda have such unusual markings? Even animals that are black and white aren’t patterned like the panda. I’m happy to report that the researcher who led the study that determined that zebras have black and white stripes to confuse biting flies, which we talked about in episode 149, seems to have solved the panda markings mystery too. Because the panda’s diet is so low in calories and nutrition, it can never build up the kind of fat stores that other bears do. As a result, it doesn’t have fat reserves that would allow it to go dormant during the winter and slee

Episode 219: The Strange and Mysterious Tarsier

Thanks to Phoebe for suggesting the tarsier, this week’s strange and interesting primate! Further Reading: Decoding of tarsier genome reveals ties to humans Long-lost ‘Furby-like’ Primate Discovered in Indonesia Tarsiers look like weird alien babies: A tarsier nomming on a lizard: A tarsier nomming on an insect: The pygmy tarsier and someone’s thumb: There’s probably not much going on in that little brain: Show Transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This week we’re looking at a weird and amazing little primate, but it’s not a monkey or ape. It’s the tarsier, with thanks to Phoebe who suggested it. It’s pronounced tarsiAY or tarsiER and both are correct. The tarsier is such a little mess that until relatively recently scientists weren’t even completely certain it was a primate. A 2016 genetic study determined for sure that it is indeed a primate even though it differs in many ways from all other primates alive. For instance, it’s a carnivore. Most primates are herbivores and some are omnivores, including humans and chimpanzees, but only the tarsier is an obligate carnivore. That means it has to eat meat and only meat, whether it’s invertebrates, birds, reptiles, or small mammals like rodents. Scientists divide primates into two groups informally, into wet-noses and dry-noses. Wet-nose doesn’t refer to a nose that’s runny but to a nose that stays moist, like a dog’s nose. This splits along the same lines as simians and prosimians, another way to group primates. Humans and other apes, along with monkeys, are simians, and also dry-noses. If you’re not sure if that’s accurate, just touch the end of your nose. Make sure you’re not standing in the rain or just got out of the bathtub, though. All other primates are wet-noses, and also prosimians, except for the tarsier. The tarsier is sort of in between. It’s grouped with the wet-nose primates, but it turns out to be more closely related to the dry-nose primates than the wet-noses. Also, its nose is actually dry. One interesting difference between prosimians and simians concerns vitamin C. Vitamin C is found in a lot of foods, but especially in fruit and vegetables. If you don’t have any vitamin C in your diet, you will eventually die of scurvy like an old pirate, so make sure to eat plenty of fruit and vegetables. But most animals don’t need to eat foods containing vitamin C because their bodies already produce the vitamin C they need. Humans, apes, and monkeys have to worry about scurvy but prosimians don’t. But the tarsier does need vitamin C even though it’s a prosimian. A lot of researchers think the tarsier should be grouped with the simians, not prosimians. The tarsier currently lives only in southeast Asia, mostly on forested islands, although tarsier fossils have been found throughout Asia, Europe, and North America. Genetic studies also indicate it probably started evolving separately from other primates around 55 million years ago in what is now China. As it happens, we have a fossil that appears to be an early ancestor of the tarsier. Archicebus achilles was discovered in 2003 and studied for an entire decade before it was described in 2013, and it lived about 55 million years ago in what is now central China. It looks a lot like a tiny tarsier, but with smaller eyes that suggest it was active during the day. Its feet were shaped like a monkey’s, though, not like a tarsier’s feet. It probably only weighed about an ounce, or 28 grams. That’s about the same weight as a pencil. It had sharp little teeth and probably ate insects. So far the 2003 specimen is the only one found, but it’s remarkably complete so researchers have been able to learn a lot about it. If I’d been one of the scientists studying it, there is no way I could have waited ten whole years to tell people about it. I’d have studied it for like six months and then thought, “Okay, good enough, HEY EVERYONE LET ME TELL YOU ABOUT THIS COOL ANIMAL.” The tarsier is nocturnal and has enormous eyes to help it see better in the dark. Its eyes are so big and round, and frankly the tarsier is not the brainiest animal, that its eyes are actually bigger than its brain. The tarsier also has mouse-like ears, long fingers and toes with sucker-like discs at the end to help it grip branches, and an extremely long tail that’s scaly on the underside. It spends almost its whole life in trees, where it climbs and jumps from branch to branch. When it climbs up a tree, it presses its long tail against the trunk to help it balance. It’s not a big animal, though. A typical tarsier measures about six inches long, or 15 cm, from the top of its little round head to the bottom of its bottom, not counting its tail. Its tail can be almost a foot long, or 25 cm, though, and its hind legs are also extremely long, about as long as the tail. Its body is rounded with short plush fur, usually brown, gray, or dark gold in color. With its big eyes and chonky body, if

Look closely: Show Transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. Back in episode 116, we talked about some amazing hoofed animals. This week we’re going to look at some more amazing hoofed animals that you may have never heard about. Some are extinct but some are running around out there looking awesome even as we speak! Thanks to Page, Elaine, Pranav, Richard E., Richard from NC, and Llewelly for their suggestions! If you’re a Patreon subscriber you may recognize part of the end of the episode as largely from a Patreon episode, by the way. Let’s start with an extinct deer with amazing antlers. Llewelly suggested it, or more accurately replied to a Twitter conversation mentioning it. That counts as a suggestion. It’s been a while but I think the conversation was about the Hobbit movies. Eucladoceros was a deer the size of a moose but with much weirder antlers. We’re not talking about the Megaloceros, often called the Irish elk, although it was distantly related. Eucladoceros’s antlers were much different. They branched up and out but were spiky like an ordinary deer’s antlers instead of palmate like a moose’s or Megaloceros’s antlers. But they were seriously big, with up to twelve points each and over five and a half feet across, or 1.7 meters. The deer itself stood just under 6 feet tall at the shoulder, or 1.8 meters. It’s often called the bush-antlered deer because the antler’s many points look like the branches of a bush. Eucladoceros lived in Eurasia but we’re not completely sure when it went extinct or why. We don’t really know that much about it at all, in fact, which is surprising because it was such a big animal. It was one of the earliest deer with branching antlers and it probably went extinct before humans encountered it, but we don’t know that for sure either. Another deer relation is a gigantic animal called the stag moose that lived at the very end of the Pleistocene, or ice age, until around 13,000 years ago. It probably looked a lot like a huge, muscular deer more than a moose, but had moose-like antlers that grew up to 6 1/2 feet across, or 2 meters. The animal itself stood almost six feet tall at the shoulder, or 1.8 m, which is about the size of the modern moose. It lived in northern North America until melting glaciers allowed other animals to migrate into the area, and the modern moose outcompeted its cousin. Early deer and deer relations looked a lot different from the deer we’re familiar with today. For instance, Hoplitomeryx. It was a ruminant and therefore related to modern deer, but while it probably looked a lot like a deer, it didn’t have antlers. It had horns. Antlers grow every year from the skull and the animal sheds them later, usually after breeding season. Horns are permanent, usually made of a bony core with a keratin sheath over it. Hoplitomeryx lived around 11 to 5 million years ago in one small area of Europe. Specifically, it lived on a large island near what is now Italy, although the island is now part of a little peninsula. It probably also lived on other, smaller islands nearby. While some specimens found are quite small, probably due to island dwarfism, some grew as big as the bush-antlered deer, over 5 ½ feet tall, or 1.7 meters. It had a pair of horns that were shaped like a modern goat’s, that grew from the top of its head and curved backwards. And it had a smaller pair of horns underneath those horns that grew outward. And it had a single horn that was about the same size or bigger and shaped the same as the goat-like horns, but which grew in the middle of the forehead like a really weird unicorn. Also, it had fangs. I am not making this up. It’s sometimes called the five-horned deer for obvious reasons. We also don’t know much about Hoplitomeryx except that it was really awesome, so let’s move on to our next strange hoofed animal. This one is a suggestion by Page, who wanted to know more about the gerenuk. We talked about it in episode 167 but it’s such an interes

I’m your host, Kate Shaw. We’re long overdue for an episode about a mystery animal, so this week let’s look at not one, not two, but three mysteries! They’re all small scientific mysteries, not big spooky ones, but I think you’ll find them interesting. We’ll start at an archaeological dig in China. In 2004, archaeologists excavated a noblewoman’s tomb in northwestern China, which they dated to about 2,200 to 2,300 years old. The tomb might have been for a woman called Lady Xia, who was the grandmother of the first emperor of China. So, kind of a big deal. The archaeologists discovered twelve pits in the tomb, and each pit contained the skeletons of various animals, some of them domesticated animals but some of them wild. Having a private menagerie was a status symbol back then, as it sometimes has been in other cultures around the world. In pit #12, they found remains of a leopard, a black bear, a crane, a lynx, and a type of small ape called a gibbon. The gibbon remains were a surprise, because today all species of gibbon in China live only in the very southern areas and are critically endangered by habitat loss and hunting. Either a gibbon had been transported hundreds of miles over difficult terrain 2,300 years ago, or gibbons lived in the area. Gibbons are small apes and there are 16 species alive today. They all live in southern Asia. We talked about the siamang in episode 76, and the siamang is a type of gibbon. Many gibbons, including the siamang, have inflatable resonant chambers in the throat to amplify their calls, but all gibbons make loud, often musical sounds to communicate with each other. They spend most of the time in treetops and mostly eat fruit, along with other plant material. Because this part of northwestern China is subtropical, and because it’s been so long since the animals died, the skeletons aren’t complete. The only gibbon bones left were part of a cranium and mandible. Obviously, scientists had to be careful with the bones and couldn’t run any tests that might damage them. They made a 3D scan of the bones and used the scan to compare the gibbon’s skull and jaw with those of living species of gibbon, to determine what species it was. It turned out that not only was it a species unknown to science, it was different enough from other gibbons that it belonged in its own genus. According to experts in Chinese history and literature, gibbons were considered noble animals that often appeared in paintings and poetry. Various species of gibbon lived throughout much of China until around the 14th century. After the 14th century, though, habitat loss and hunting drove the gibbons farther south until now there are almost no gibbons left in China. Lady Xia’s pet gibbon is the first species known that definitely went extinct in the modern era, which makes it even more important that the gibbons still alive today are protected along with their habitats. Speaking of ancient paintings of animals, 4,600 years ago, an artist made a painting of some geese for a tomb in Egypt. The painting is five feet long, or 1.5 meters, and is a fragment of a larger wall decoration that has been lost. It’s called the “Meidum Geese.” It’s a lovely painting and the geese are incredibly lifelike—so lifelike, in fact, that it should be easy to identify them. But maybe not quite so easy after all. There are three species of geese in the painting. Two are probably the graylag goose and the greater white-fronted goose. The third looks similar to the red-breasted goose, but there are enough differences that researchers aren’t sure. No red-breasted goose remains have ever been found in Egypt; it only lives in Europe and Asia. It’s quite likely that the mystery goose is an extinct species. Other animal species depicted in Egyptian art are extinct now, even though they were common when the art was made. Egypt’s climate is much dryer than it was thousands of years ago, so na

Episode 216: Gentle Giant Sharks

Let’s learn about some of the biggest sharks in the sea–but not sharks that want to eat you!

The basking shark, also with a mega mouth: The whale shark: Leedsichthys problematicus (not a shark): Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This week we’re going to look at some huge, weird sharks, but they’re not what you may expect when you hear the word shark. Welcome to the strange world of giant filter feeders! This episode is inspired by an article in the brand new issue of Science, which you may have heard about online. A new species of shark is described in that issue, called the eagle shark because of the shape of its pectoral fins. They’re long and slender like wings. The fossil was discovered in 2012 in northeastern Mexico, but not by paleontologists. It came to light in a limestone quarry, where apparently a quarry worker found it. What happened to it at that point isn’t clear, but it was put up for sale. The problem is that Mexico naturally wants fossils found in Mexico to stay in Mexico, and the authors of the study are not Mexican. One of the authors has a history of shady dealings with fossil smugglers too. On the other hand, the fossil has made its way back to Mexico at last and will soon be on display at a new museum in Nuevo León. Fossils from this quarry are often extremely well preserved, and the eagle shark is no exception. Sharks don’t fossilize well since a shark’s skeleton is made of cartilage except for its teeth, but not only is the eagle shark’s skeleton well preserved, we even have an impression of its soft tissue. The eagle shark was just slightly shorter than 5 ½ feet long, or 1.65 meters. Its tail looks like an ordinary shark tail but that’s the only ordinary thing about it. The head is short and wide, without the long snout that most sharks have, it doesn’t appear to have dorsal or pelvic fins, and its pectoral fins, as I mentioned a minute ago, are really long. How long? From the tip of one pectoral fin to the other measures 6.2 feet, or 1.9 meters. That’s longer than the whole body. Researchers think the eagle shark was a filter feeder. Its mouth would have been wide to engulf more water, which it then filtered through gill rakers or some other structure that separated tiny animals from the water. It expelled the water through its gills and swallowed the food. The eagle shark would have been a relatively slow swimmer. It glided through the water, possibly flapping its long fins slowly in a method called suspension feeding, sometimes called underwater flight. If this makes you think of manta rays, you are exactly correct. The eagle shark occupied the same ecological niche that manta rays do today, and the similarities in body form are due to convergent evolution. Rays and sharks are closely related, but the eagle shark and the manta ray evolved suspension feeding separately. In fact, the eagle shark lived 93 million years ago, 30 million years before the first manta remains appear in the fossil record. The eagle shark lived in the Western Interior Seaway, a shallow sea that stretched from what is now the Gulf of Mexico straight up through the middle of North America. Because it’s the only specimen found so far, we don’t know when it went extinct, but researchers suspect it died out 65 million years ago at the same time as the non-avian dinosaurs. We also don’t have any preserved teeth, which makes it hard to determine what sharks it was most closely related to. Hopefully more specimens will turn up soon. Now that we’ve mentioned the manta ray, let’s talk about it briefly even though it’s not a shark. It is big, though, and it’s a filter feeder. If you’ve never seen one before, they’re hard to describe. If it had gone extinct before humans started looking at fossils scientifically, we’d be as astounded by it as we are about the eagle shark—maybe even moreso because it’s so much bigger. Its body is sort of diamond-shaped, with a blunt head and short tail, but elongated fins that are broad at the base but end in drawn-out points. Manta rays are measured in width, sometimes called a wingspan since their long fins resemble wings that allow it to fly underwater. There are two species of manta ray, and even the smaller one has a wingspan of 18 feet, or 5.5 meters. The larger species can grow 23 feet across, or 7 meters. Some other rays are filter feed

I’m your host, Kate Shaw. This week I promised we’d cover a cute, happy animal to make up for last week’s extinction event episode, but instead of mammals let’s look at some cute invertebrates! One of them is even a mystery animal. Thanks to Page and Lorenzo for suggesting two of the animals we’re going to cover today! We’ll start with Lorenzo’s suggestion, the pea aphid. Years and years ago I spent a slow day at work making a list of cute foods with a coworker, and peas were at the top of the list. Blueberries were second and I don’t remember the rest of the list. Generally, cuteness depended on how small the food was and how round. Aphids are really small and peas are round, so the pea aphid has to be adorable. The pea aphid, however, is not round. It’s shaped sort of like a tiny pale-green teardrop with long legs, long antennae, and teeny black dots for eyes. It’s actually kind of big for an aphid, not that that’s saying much since it only grows 4 mm long at most. It’s called the pea aphid because it likes to live on pea plants, although it’s also happy on plants related to peas, such as beans, clover, and alfalfa. Cute as it is, farmers and gardeners do not like the pea aphid because it eats the sap of the plants it lives on, which can weaken the plant and can spread plant diseases. During most of the year, all pea aphids are females. Each adult produces eggs that don’t need to be fertilized to hatch, but instead of laying her eggs like most insects, they develop inside her and she gives birth to live babies, all of them female. An aphid can have up to 12 babies a day, called nymphs, and the nymphs grow up in about a week or a little longer. Then they too start having babies. Even though lots of other insects and other animals eat aphids, as you can see, they will always be numerous. As the summer turns to fall and the days become shorter, some of the baby aphids are born with wings. Some are also born male, and sometimes the males also have wings, although they might not have mouths. These males and winged females mate and the females fly off to lay their eggs on clover and alfalfa plants, assuming they aren’t already on clover or alfalfa plants. The eggs don’t hatch until spring, and all the resulting nymphs are female. Sometimes winged females are born if the plants where the aphids live get too crowded. The winged females can fly away and find new plants. If you’ve ever had a garden, you’re probably familiar with aphids. They spend most of the time on the undersides of leaves, drinking sap through specialized mouthparts called stylets. You may also have noticed that when you try to smush the aphids, all of them immediately drop to the ground. This protects them not just from being smooshed by a gardener’s thumb, but from being eaten along with the leaves when a deer or other animal browses on the plants where they live. Sometimes, instead of being leaf green, pea aphids are a pale reddish color. This is called the red morph. Red morph pea aphids are more likely to live on certain plants while the ordinary green pea aphids are more likely to live on others, although many times you can find both varieties on a single plant. The red coloration of red morph pea aphids is due to larger quantities of a chemical called carotenoid [kerOTenoid] in its body. All pea aphids contain carotenoids, though, and it’s not just used for coloration. Research suggests that the carotenoids absorb sunlight and produce energy that the aphid can use. It’s a limited form of photosynthesis—you know, that thing that only plants do. Not only that, the pea aphid produces the carotenoids in its body. Every other animal that needs carotenoids absorbs them from plants it eats, with the possible exception of a type of mite. The genetic sequence that allows the pea aphid to make its own carotenoids originally came from fungi. Somehow the aphid captured the genetic material from fungi, probably after eating it, and passed those genes down to its descendants. This is call

Episode 214: Armored Fish and the Late Devonian Mass Extinctions

It’s the next in our short series of episodes about mass extinctions! Don’t worry, it won’t be boring, because we’re going to learn about a lot of weird ancient fish too. Further reading: Titanichthys: Devonian-Period Armored Fish was Suspension Feeder Behind the Scenes: How Fungi Make Nutrients Available to the World Dunkleosteus was a beeg feesh with sharp jaw plates that acted as teeth: Titanichthys was also a beeg feesh, but it wouldn’t have eaten you (picture from the Sci-News article linked above): Pteraspis: NOSE HORN FISH: Cephalaspis had no jaws so it couldn’t chomp you: Bothriolepis kind of looked like a fish in a mech suit: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. Here’s the second in our small series of episodes about extinction events, this one the Late Devonian extinction. We’ll also learn about some weird and amazing fish that lived during this time, and a surprising fact about ancient trees. The Devonian period is often called the Age of Fish because of the diversity of fish lineages that arose during that time. It lasted from roughly 420 million years ago to 359 million years ago. During the Devonian, much of the earth’s landmasses were smushed together into the supercontinent Gondwana, which was mostly in the southern hemisphere, and the smaller continents of Siberia and Laurussia in the northern hemisphere. The world was tropically warm, ocean levels were high, and almost all animal life lived in the oceans. Some animals had adapted to living on land at least part of the time, though, and plants had spread across the continents. The first insects had just evolved too. Shallow areas of the ocean were home to animals that had survived the late Ordovician extinctions. There were lots of brachiopods, bivalves, crinoids, trilobites, and corals. Eurypterids were still thriving and ammonites lived in deeper water. But while all these animals are interesting, we’re mainly here for the fish. The fish of the Devonian were very different from modern fish. Most had armor. Way back in episode 33 we talked about the enormous and terrifying dunkleosteus, which lived in the late Devonian. It might have grown up to 33 feet long, or 10 meters. Since we still don’t have any complete specimens, just head plates and jaws, that’s an estimate of its full size. However long it grew, it was definitely big and could have chomped a human in half without any trouble at all. It’s probably a good thing mammals hadn’t evolved yet. Instead of teeth, dunkleosteus had jaw plates with sharp edges and fanglike projections that acted as teeth. Another huge fish from the Devonian is called titanichthys, which might have grown as long as dunkleosteus or even bigger, but which was probably not an apex predator. Its jaw plates were small and blunt instead of sharp, which suggests it wasn’t biting big things. It might not have been biting anything. Some researchers think titanichthys might have been the earliest known filter feeder, filtering small animals from the water by some mechanism we don’t know about yet. Filter feeders use all sorts of adaptations to separate tiny food from water, from gill rakers to baleen plates to teeth that fit together closely, and many others. A study published in 2020 compared the jaw mechanisms of modern giant filter feeders (baleen whales, manta rays, whale sharks, and basking sharks) to the jaw plates of titanichthys, as well as the jaw plates of other placoderms that were probably predators. Titanichthys’s jaws are much more similar to those of modern filter feeders, which it isn’t related to at all, than to fish that lived at the same time as it did and which it was related to. Titanichthys and dunkleosteus were both placoderms, a class of armored fish. That wasn’t unusual, actually. In the Devonian, most fish ended up evolving armored plates or thick scales. What was unusual in placoderms were their jaws. Specifically, the fact that they had jaws at all. Placoderms were probably the first fish to evolve jaws. Pteraspis, for instance, was an armored fish that wasn’t a placoderm. It had no fins at all but it was a good swimmer, streamlined and possibly a predator, although it might have been a plankton feeder at the surface of the ocean. It grew about 8 inches long, or 20 cm. It used its tail to propel itself through the water, and instead of fins it had spines growing from its armor that helped keep it stable. A spine on its back, near the rear of the body armor, acted as a dorsal fin, while spines on the sides of its armor, just over its gills, acted like pectoral fins. It also had some smaller spines along its back and a big spike on its nose. Probably not a good fish to swallow whole. Cephalaspis lived in the early Devonian, around 400 million years ago in fresh water. It wasn’t very big, maybe a foot long, or 30 cm. Basically, it would have fit nicely on a dinner plate, but it wouldn’t have looked much like a trout

Episode 213: More Honeybees, But Stingless

Thanks to Nicholas for this week’s suggestion! Let’s learn about the Australian stingless bee and its relatives! Listen to BewilderBeasts if you want more fun, family-friendly animal facts! Further reading/watching: Australian Stingless Bees Women Work to Save Native Bees of Mexico (I really recommend the short video embedded on this page! It’s utterly charming!) House of the Royal Lady Bee: Maya revive native bees and ancient beekeeping A Maya beekeeper’s hut and some Central/South American stingless bees (pictures from the last link, above): Stingless bees build their combs in a spiral shape: An Australian stingless bee collecting nectar and pollen: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. Last year Nicholas emailed me with a correction to episode 183 and a suggestion. In that episode I said that only honeybees make honey, but Nicholas pointed out that the Australian stingless bee also makes honey. In fact, he keeps some of these bees himself! So let’s learn about Tetragonula carbonaria and its close relations, as well as some other interesting bee information! Stingless bees don’t just live in Australia. Different species live in parts of Australia, Africa, Asia, and Central and South America. Most produce honey, although not very much of it compared to the European honeybee. They don’t sting but some species will bite. Stingless bees are much smaller than European honeybees. Some look more like a flying ant than a bee unless you look closely. A stingless bee worker only grows around 4 mm long, while a European honeybee worker grows about 15 mm long. Different species have different markings, but Tetragonula carbonaria, which is sometimes called the sugarbag bee, is black all over. Stingless bees have a lot in common with honeybees, which makes sense because they’re closely related. The stingless bee lives in a social colony with a caste structure of the queen who stays home and lays eggs, male drones that mate with new queens, and infertile female workers. Young worker bees keep the hive clean and take care of the brood, or developing larvae, while older worker bees are the ones who fly out and forage for pollen and nectar. While stingless bees only have one queen laying eggs at any given time, some species will have a few backup queens in case of an emergency. These backup queens don’t produce eggs because they only mate with the drones if the reigning queen dies. In a few species of stingless bee, there’s actually another caste in addition to the ordinary queen, drone, and worker. It’s the soldier caste. Soldier bee larvae get extra food, and they grow to be larger and stronger than other bees to help them guard the colony, especially the hive entrance. Before the stingless bee soldier castes were discovered, no one realized that any bees ever had soldiers, although some ant and termite species have them. The stingless bee builds a nest in tree cavities, preferably in the tops of large trees because that keeps the hive warm and protected. It’s a tropical bee so it needs to stay warm. If any insect or other small animal gets into the hive, the bees can’t sting it because as their name implies, they don’t have working stingers. Instead, they swarm the intruder and attempt to smother it with anything they can find, including wax, resin, and mud. The stingless bee builds honeycombs, but they’re spiral shaped. They’re made from beeswax mixed with resin that the worker bees collect from certain plants. The combs can be yellow like ordinary honeycombs, or they can be black, brown, or reddish. The word honeycomb isn’t actually accurate because it’s not where the bees store honey. The honey is stored in large chambers in the nest called honeypots. The combs are properly called brood combs because they’re used for baby bees. Worker bees fill the cells about three-quarters full of honey and pollen and the queen lays one egg in each cell. The workers then cap the cell. When the egg hatches, the bee larva has plenty of nutritious honey and pollen to eat. Once the larva has metamorphosed into an adult bee, it chews a hole through the cell’s cap and emerges. If you’re wondering whether you can eat the honey of the sugarbag bee, yes! It’s runnier than ordinary honey but it smells wonderful and according to Nicholas, it has a tangy citrusy flavor. It sounds really good. Stingless bees don’t produce nearly as much honey as European honeybees, though, which makes sense since honeybees have been selectively bred over centuries to produce more honey than the hive could possibly need. The beekeeper takes the extra to eat, but naturally leaves plenty for the hive to live on. People in Australia only started keeping stingless bees around the early 1980s, but it’s growing more and more popular. Since the bees are native to Australia, they’re much better for the environment than the European honeybee. They’re also incredibly good at pollinating crops, and if the wea

Episode 212: The River of Giants

Thanks to Pranav for his suggestion! Let’s find out what the river of giants was and what lived there! Further reading: King of the River of Giants Spinosaurus was a swimming dinosaur and it swam in the River of Giants: A modern bichir, distant relation to the extinct giants that lived in the River of Giants: Not actually a pancake crocodile: A model of Aegisuchus and some modern humans: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. A while back, Pranav suggested we do an episode about the river of giants in the Sahara. I had no idea what that was, but it sounded interesting and I put it on the list. I noticed it recently and looked it up, and oh my gosh. It’s amazing! It’s also from a part of the world where it’s really hot, as a break for those of us in the northern hemisphere who are sick of all this cold weather. I hope everyone affected by the recent winter storms is warm and safe or can get that way soon. The Sahara is a desert in northern Africa, famous for its harsh climate. Pictures of the Sahara show its huge sand dunes that stretch to the horizon. This wasn’t always the case, though. Only about 5,500 years ago, it was a savanna with at least one lake. Lots of animals lived there and some people too. Before that, around 11,000 years ago, it was full of forests, rivers, lakes, and grasslands. Before that, it was desert again. Before that, it was forests and grasslands again. Before that, desert. The Sahara goes through periodic changes that last around 20,000 years where it’s sometimes wet, sometimes dry, caused by small differences in the Earth’s tilt which changes the direction of the yearly monsoon rains. When the rains reach the Sahara, it becomes green and welcoming. When it doesn’t, it’s a desert. Don’t worry, we only have 15,000 more years to wait until it’s nice to live in again. This wet-dry-wet pattern has been repeated for somewhere between 7 and 11 million years, possibly longer. Some 100 million years ago, though, the continents were still in the process of breaking up from the supercontinent Gondwana. Africa and South America were still close together, having only separated around 150 million years ago. The northern part of Africa was only a little north of the equator and still mostly attached to what is now Eurasia. Near the border of what is now Morocco and Algeria, a huge river flowed through lush countryside. The river was home to giant animals, including some dinosaurs. Their fossilized remains are preserved in a rock formation called the Kem Kem beds, which run for at least 155 miles, or 250 km. A team of paleontologists led by Nizar Ibrahim have been working for years to recover fossils there despite the intense heat. The temperature can reach 125 degrees Fahrenheit there, or 52 Celsius, and it’s remote and difficult to navigate. For a long time researchers were confused that there were so many fossils of large carnivores associated with the river, more than would be present in an ordinary ecosystem. Now they’ve determined that while it looks like the fossils were deposited at roughly the same time from the same parts of the river, they’re actually from animals that lived sometimes millions of years apart and in much different habitats. Bones or even fossils from one area were sometimes exposed and washed into the river along with newly dead river animals. This gives the impression that the river was swarming with every kind of huge predator, but it was probably not quite so dramatic most of the time. Then again, there were some really fearsome animals living in and around the river in the late Cretaceous. One of the biggest was spinosaurus, which we talked about in episode 170. Spinosaurus could grow more than 50 feet long, or 15 m, and possibly almost 60 feet long, or 18 m. It’s the only dinosaur known that was aquatic, and we only know it was aquatic because of the fossils found in the Kem Kem beds in the last few years. Another dinosaur that lived around the river is Deltadromeus, with one incomplete specimen found so far. We don’t have its skull, but we know it had long, slender hind legs that suggests it could run fast. It grew an estimated 26 feet long, or 8 meters, including a really long tail. At the moment, scientists aren’t sure what kind of dinosaur Deltadromeus was and what it was related to. Some paleontologists think it was closely related to a theropod dinosaur called Gualicho, which lived in what is now northern Patagonia in South America. Remember that when these dinosaurs were still alive, the land masses we now call Africa and South America had been right in the middle of a supercontinent for hundreds of millions of years, and only started separating around 150 million years ago. Gualicho looked a lot like a pocket-sized Tyrannosaurus rex. It grew up to 23 feet long, or 7 meters, and had teeny arms. Deltadromeus’s arms are more in proportion to the rest of its body, though. Some of the biggest dinosaurs found in the Ke

Episode 211: The Magnificent Fin Whale

This week let’s venture into the ocean and learn about the fin whale! Further reading: The songs of fin whales offer new avenue for seismic studies of the oceanic crust Fin whales’ big gulp The fin whale can hold a whole lot of water in its mouth (illustration from the second article linked above): A fin whale underwater. Look at that massive tail. That’s pure muscle: A fin whale above water. It’s like a torpedo: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. It’s been too long since we had an episode about whales. Yes, okay, two weeks ago we talked about a couple of newly discovered whales, but I want to really learn about a particular whale. So this week, let’s look at the fin whale. The fin whale is a baleen whale that’s only a little less enormous than the blue whale. The longest fin whale ever reliably measured was 85 feet long, or just a hair shy of 26 meters, but there are reports of fin whales that are almost 90 feet long, or a bit over 27 meters. An average American school bus is half that length, so a fin whale is as long as two school buses. Even a newborn fin whale calf is enormous, as much as 21 feet long, or 6.5 meters. Females are on average larger than males. It’s a long, slender whale that’s sometimes called “the greyhound of the sea,” because it’s also really fast. It can swim up to 29 mph, or 46 km/hour, and possibly faster. If that doesn’t sound too fast, consider that the Olympic gold-medal swimmer Michael Phelps topped out at about 4.7 miles per hour, or 7.6 km/h. Like other baleen whales, the fin whale has a pair of blowholes instead of just one. On its underside, it has up to 100 grooves that extend from its chin down to its belly button. Yes, whales have belly buttons. They’re placental mammals, and all mammals have belly buttons because that’s where the umbilical cord is attached when a developing baby is in its mother’s womb. I don’t know what a whale’s belly button looks like. Also, the proper term for belly button is navel, and if you’re wondering, that’s where navel oranges get their name, because they have that weird thing on one end that looks like a belly button. It’s not, though. I don’t know what it is. You’ll have to find a podcast called Strange Plants to explain it. Anyway, the grooves on the fin whale’s underside act as pleats, or accordion folds. Other baleen whales have these pleats too. A baleen whale eats tiny animals that it filters out of the water through its baleen plates, which are keratin structures in its mouth that take the place of teeth. The baleen is tough but thin and hangs down from the upper jaw. It’s white and looks sort of like a bunch of bristles at the end of a broom. The whale opens its mouth wide while lunging forward or downward, which fills its huge mouth with astounding amounts of water. As water enters the mouth, the skin stretches to hold even more, until the grooves completely flatten out. The water it can hold in its mouth is about equal to the size of a school bus. Technically, though, a lot of that water isn’t in the whale’s mouth. It’s in a big pocket between the body wall and the blubber underneath the skin. The ballooning out of the pocket stretches the nerves in the mouth and tongue to more than twice their length, and then the nerves have to fold back up tightly after the water is pushed out. The nerves fold in a complicated double layer to minimize damage during all this stretching. After the whale fills its mouth with water, it closes its jaws, pushing its enormous tongue up, and forces all that water out through the baleen. Any tiny animals like krill, copepods, small squid, small fish, and so on, get trapped in the baleen. It can then swallow all that food and open its mouth for another big bite. Even more amazing, this whole operation, from opening its mouth to swallowing the food, only takes six to ten seconds. Because it only eats small animals, the fin whale’s esophagus (which is the inside part of the throat) is actually quite narrow considering what a huge animal it is. In other words, it could not possibly swallow a human, in case you were worried. I was worried. If you did end up in a fin whale’s mouth, it would just spit you back out. Baleen whales have a sensory organ on the chin that’s found in no other animal. It’s about the size of a grapefruit and situated between the tips of the jaws. It probably helps the whale determine how much potential food is in the water, which saves it from wasting time and energy gulping in water and filtering it out when there’s nothing much to eat. The fin whale looks a lot like the blue whale and the two species are closely related, so much so that they sometimes interbreed and produce hybrid babies. It usually lives in small groups of up to around 10 individuals and a female fin whale has one baby every two or three years. It probably migrates seasonally to new feeding grounds, but we don’t actually know a whole lot about where

Episode 210: The Mysterious Lightbulb Lizard

Does the Shreve’s lightbulb lizard really emit light? (Hint: sort of.) Let’s find out! Further reading: The Lightbulb Lizard of Benjamin Shreve Shreve’s lightbulb lizard, looking pretty ordinary really: A web-footed gecko in moonlight: A Jamaican gray anole showing off his dewlap: Show Transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This week let’s learn about an interesting reptile with a mystery that’s mostly solved, but still really weird. It’s called Shreve’s lightbulb lizard. The story of this little lizard starts in 1937, when zoologist Ivan Sanderson was collecting freshwater crabs on a mountaintop in Trinidad. They were probably mountain crabs, also called the manicou crab, which is actually a pretty astonishing animal on its own. It’s a freshwater crab that doesn’t need to migrate to the ocean to release its eggs into the water. Instead, the female carries her eggs in a pouch in her abdomen. The eggs hatch into miniature crabs instead of larvae, and they stay in her pouch until they’re old enough to strike out on their own. The mountains of Trinidad are made of limestone, which means they’re full of caves, and Sanderson was reportedly catching crabs in an underground pool or stream. He noticed a flash of light in the darkness and naturally went to find what had made it. All he found was a little lizard hiding under a ledge. It looked kind of like a brown skink and was pretty boring, but when the lizard turned its head, Sanderson saw a flash of dotted light down both its sides. When he caught the lizard and examined it while it was sitting in his hand, it flashed its lights again. Sanderson knew he’d found something extraordinary, because lizards don’t bioluminesce. We still don’t know of any terrestrial vertebrate that emits light. Lots and lots of marine animals do, and some terrestrial invertebrates like lightning bugs and glow-worms, but no terrestrial vertebrates. Sanderson took the lizard back to his camp, where he and his team observed it in different situations to see if it would light up again. They moved it to warmer areas and colder ones, made loud noises nearby, even tickled it, and they did indeed see it light up a few times. The light came from a row of tiny eyespots along its sides, from its neck to its hips. It had one row of these spots on each side, and each spot looked like a tiny white bead. The greenish-yellow flashes of light seemed to shine through the spots, as Sanderson said, like “the portals on a ship.” Sanderson sent the lizard to The British Museum in London where another zoologist studied it and discovered that it was actually a known species, but apparently very rare. Only two specimens had ever been caught, one a juvenile and one an adult female. The lizard Sanderson caught was male, and it turns out that only adult males have these little eyespots. Sanderson later caught seven more of the lizards. Let’s jump forward a bit and get a better idea of what these lizards look like. Shreve’s lightbulb lizard grows around 5 inches long at most, or 13 cm, not counting its long tail. It has short legs, a pointy nose, and broad, flat scales on its back and sides. It’s mostly brown in color. It lives in high elevations in the Caribbean island of Trinidad and Tobago, which is just off the coast of Venezuela in South America. It prefers cool climates, unlike most reptiles, and while it turns out that it’s not actually very rare, it’s also hard to study because it lives in such remote areas, so we don’t know much about it. It may be nocturnal and it may be semi-aquatic. It certainly lives along mountain streams, where it eats insects and other small animals. Now, we have mentioned Ivan Sanderson a number of times in past episodes, and you may remember me sounding pretty skeptical about some of his cryptozoological claims. But Sanderson was a zoologist with a good reputation as a field scientist, and more importantly, he wasn’t the only one who saw the lizard light up. The British Museum zoologist, H.W. Parker, who studied the first lizard Sanderson found, was actually the scientist who had originally discovered the lizard a few years before. He was very interested in the little portholes along the male lizard’s sides and studied them carefully. But he couldn’t find anything about them that indicated how they lit up. Each tiny eyespot consisted of a transparent center spot with a ring of black skin around it. The eyespots did not contain glowing bacteria, specialized nerve endings, ducts, reflecting structures, or anything else that he could think of that might cause a flash of light. Other zoologists examined the so-called lightbulb lizard over the next few decades and none of them saw it emit light either. By 1960 no one believed it was bioluminescent. I’m taking most of my information from a blog post by Dr Karl Shuker, a zoologist who writes a lot about cryptozoological mysteries. If you want to read his article, there’s a link in the

Episode 209: Animals Discovered in 2020

I’m your host, Kate Shaw. Very recently, Page suggested the topic “animals discovered in 2020.” Since I was already thinking of doing something like this, I went ahead and bumped his suggestion to the top of the list and here we go! You’d think that with so many people in the world, there wouldn’t be too many more new animals to discover, especially not big ones. But new scientific discoveries happen all the time! Many are for small organisms, of course, like frogs and insects, but there are still unknown large animals out there. In fact, 503 new animals were officially discovered in 2020. Every single one is so amazing that I had a hard time deciding which ones to highlight. In most cases we don’t know much about these new animals since studying an animal in the wild takes time, but finding the animal in the first place is a good start. Many of the newly discovered species live in the ocean, especially the deep sea. In April of 2020, a deep-sea expedition off the coast of western Australia spotted several dozen animals new to science, including what may be the longest organism ever recorded. It’s a type of siphonophore, which isn’t precisely a single animal the way that, say, a blue whale is. It’s a colony of tiny animals, called zooids, all clones although they perform different functions so the whole colony can thrive. Some zooids help the colony swim, while others have tiny tentacles that grab prey, and others digest the food and disperse the nutrients to the zooids around it. Many siphonophores emit bioluminescent light to attract prey. Some siphonophores are small but some can grow quite large. The Portuguese man o’ war, which looks like a floating jellyfish, and which we talked about way back in episode 16, is actually a type of siphonophore. Its stinging tentacles can be 100 feet long, or 30 m. Other siphonophores are long, transparent, gelatinous strings that float through the depths of the sea, snagging tiny animals with their tiny tentacles, and that’s the kind this newly discovered siphonophore is. The new siphonophore was spotted at a depth of about 2,000 feet, or 625 meters, and was floating in a spiral shape. The scientists estimated that the spiral was about 49 feet in diameter, or 15 meters, and that the outer ring alone was probably 154 feet long, or 47 meters. The entire organism might have measured 390 feet long, or almost 119 meters. It’s been placed into the genus Apolemia although it hasn’t been formally described yet. Another 2020 discovery off the coast of Australia was an entire coral reef a third of a mile tall, or 500 meters, and almost a mile across, or 1.5 km. It’s part of the Great Barrier Reef but isn’t near the other reefs. A scientific team mapping the seafloor in the area discovered the reef and undoubtedly did a lot of celebrating. I mean, it’s not every day that you find an entirely new coral reef. They were able to 3D map the reef for study and take video too. Best of all, it’s a healthy reef with lots of other animal life living around it. Another big animal discovered in 2020 is one Patreon subscribers already know about, because we started out the year with an episode all about it. It’s a new whale! In 2018 scientists recording audio of animal life around Mexico’s San Benito Islands in the Pacific Ocean heard a whale call they didn’t recognize. They thought it probably belonged to a type of beaked whale, probably a little-known species called Perrin’s beaked whale. In late 2020 a team went back to the area specifically to look for Perrin’s beaked whales. They did see three beaked whales and got audio, video, and photographs of them, but they weren’t Perrin’s beaked whales. The whale specialists on the expedition didn’t know what these whales were. They don’t match any sp

All they need is some Doublemint Gum: Two (dead, stuffed) wombats glowing under ultraviolet light: Show Transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This week we’re going to look at two super-cute animals from Australia, both of them suggestions by Phoebe. Thank you, Phoebe! Let’s start with the quokka. It’s a marsupial, which as you may recall means that it’s a mammal that gives birth to babies that aren’t fully formed yet, and the babies then finish developing in the mother’s pouch. It’s related to kangaroos and wallabies but is quite small, around the size of an ordinary domestic cat. It’s kind of a chonk, though, which means it’s probably closer in size to my big chonk cat Dracula. It’s shaped roughly like a little wallaby or kangaroo but with a smaller tail and with rounded ears, and it’s grey-brown in color. You may have seen pictures of the quokka online, because the reason it’s considered so incredibly cute is because it looks like it’s smiling all the time. If you take a picture of a quokka’s face, it looks like it has a happy smile and that, of course, makes the people who look at it happy too. Those are real pictures, by the way. Because of the way its muzzle and mouth are shaped, the quokka really does look like it’s smiling. This has caused some problems, unfortunately. People who want to take selfies with a quokka sometimes forget that they’re wild animals. While quokkas aren’t very aggressive and are curious animals who aren’t usually afraid of people, they can and will bite when frightened. The Nature Conservancy of Australia recommends that people who want to take a selfie with a quokka arrive early in the morning or late in the evening, since quokkas are mostly nocturnal, and that they let the quokkas approach them instead of following one around. Touching a quokka or giving it food or drink is strictly prohibited, since it’s a protected animal. The quokka lives on a few small islands off the coast of western Australia and a few small forested areas on the mainland. The largest population lives on Rottnest Island, and in fact the island was named by a Dutch explorer who thought the quokkas were rats. It means rat’s nest. The island’s actual name was Wadjemup and it was a ceremonial area for the local Whadjuk Noongar people. Only an estimated 14,000 quokkas live in the wild today, with most of those on Rottnest Island. It used to be much more widespread, but once white settlers arrived and introduced predators like dogs, cats, and foxes, its numbers started to decline. It’s also threatened by habitat loss. It reproduces slowly, since a female only raises one baby a year. A baby quokka is born after only a month, but like other marsupial babies, called joeys, it’s just a little pink squidge when it’s born. It climbs into its mother’s pouch where it stays for the next six months. Once it’s old enough to leave her pouch, it still depends on her milk for a few more months. While she’s raising one baby, though, the mother has other babies still in her womb ready to be born but held in suspended animation. This means that if something happens to her joey and it dies, the mother can give birth to another baby very quickly. The quokka is most active at night. It sleeps during most of the day, usually hidden in a type of prickly plant that helps keep predators from bothering it. It gets most of its water needs from the plants it eats, and while it mostly hops around like a teensy kangaroo, it can also climb trees. The wombat is another adorable Australian marsupial. For some reason, I’ve talked about the wombat several times in Patreon episodes but have barely mentioned it in the main feed–but that’s about to change. Mostly because I am going to recycle a lot of the information from the Patreon episodes, but I’ve also added a lot of interesting new details. The wombat mainly lives in southern and eastern Australia, including Tasmania. It looks a little like a cartoon bear, a little like a cartoon badger, and a little like a cartoon giant hamster. Perhaps you notice a theme here. It has short legs, no tail to speak of, and is about the size of a medium-sized dog but stockier, with a broad face and rounded ea

Episode 207: The Dire Wolf!

This week we’re on the cutting edge of science, learning about the brand new genetic study of dire wolves that rearranges everything we know about the dire wolf and other canids! Also, a bonus turtle update. Further reading: Dire Wolves Were Not Really Wolves, Genetic Clues Reveal An artist’s rendition of dire wolves and grey wolves fighting over a bison carcass (art by Mauricio Anton): The pig-nosed face of the Hoan Kiem turtle, AKA Yangtze giant softshell turtle, AKA Swinhoe’s softshell turtle: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. You may have heard the news this past week about the new study about dire wolves. I thought it would make a great topic for an episode, and we’ll also have a quick update about a rare turtle that’s been in the news lately too. Dire wolves show up pretty often in movies and TV shows and video games and books, because as far as anyone knew until very recently, the dire wolf was an extra big wolf that lived in North America during the Pleistocene until it went extinct around 13,000 years ago. Researchers assumed it was a close cousin of the modern grey wolf. Well, in a brand new study published in Nature literally less than a week ago as this episode goes live, we now have results of a genetic study of dire wolf remains. The results give us surprising new information not just about the dire wolf, but about many other canids. The study started in 2016, when an archaeologist, Angela Perri, who specializes in the history of human and animal interactions, wanted to learn more about the dire wolf. She went around the United States to visit university collections and museums with dire wolf remains, and took the samples she collected to geneticist Kieren Mitchell. Perri, Mitchell, and their team managed to sequence DNA from five dire wolves that lived between 50,000 and 13,000 years ago. Then the team compared the dire wolf genome to those of other canids, including the grey wolf and coyote, two species of African wolf, two species of jackal, and the dhole, among others. To their surprise, the dire wolf’s closest relation wasn’t the grey wolf. It was the jackals, both from Africa, but even they weren’t very closely related. It turns out that 5.7 million years ago, the shared ancestor of dire wolves and many other canids lived in Eurasia. At this point sea levels were low enough that the Bering land bridge, also called Beringia, connected the very eastern part of Asia to the very western part of North America. One population of this canid migrated into North America while the rest of the population stayed in Asia. The two populations evolved separately until the North America population developed into what we now call dire wolves. Meanwhile, the Eurasian population developed into many of the modern species we know today, and eventually migrated into North America too. By the time the gray wolf populated North America, the dire wolf was so distantly related to it that even when their territories overlapped, they avoided each other and didn’t interbreed. We’ve talked about canids in many previous episodes, including how readily they interbreed with each other, so for the dire wolf to remain genetically isolated, it was obviously not closely related at all to other canids at this point. The dire wolf looked a lot like a grey wolf, but researchers now think that was due more to convergent evolution than to its relationship with wolves. Both lived in the same habitats: plains, grasslands, and forests. The dire wolf was slightly taller on average than the modern grey wolf, which can grow a little over three feet tall at the shoulder, or 97 cm, but it was much heavier and more solidly built. It wouldn’t have been able to run nearly as fast, but it could attack and kill larger animals. Its head was larger in proportion than the grey wolf’s and it had massive teeth that were adapted to crush bigger bones. The dire wolf lived throughout North America and even migrated into South America and back into east Asia. It preferred open lowlands and its most important prey animal was probably the horse, although it also ate ground sloths, camels, bison, and many others. It probably also scavenged dead animals and probably hunted as a pack. Researchers think the dire wolf went extinct due to a combination of factors, including increased competition with grey wolves and maybe with humans, climate change, and the extinction of the megaherbivores that made up its diet. It will probably be reclassified into a different genus, Aenocyon, instead of staying in its current genus, Canis. Before this study, most researchers thought that the ancestor of North American canids evolved in Eurasia, but had already migrated into North America before developing into dire wolves, grey wolves, coyotes, and other canid species. But now the history of canids has changed a lot. From what we now know, pending further study, the dire wolf was the only canid in North Americ

Such miniature floof: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This week we are finally going to look at some birds of New Guinea, a topic suggested ages ago by M Is for Awesome! There are so many weird and amazing birds in New Guinea that instead of trying to talk about a bunch of them very briefly in one episode, I’m going to make this another ongoing series throughout the year. Every so often we’ll revisit New Guinea (in our minds, anyway) and learn about a few more birds. In this episode we’ll learn some basic information about New Guinea and then learn about two really interesting birds that live there. New Guinea comes up in lots of episodes because so many animals live there. It’s almost the world’s largest island, second only to Greenland. Australia is considered a continent, not an island. New Guinea is actually pretty close to Australia so there’s a lot of overlap between animals that live in Australia and animals that live in New Guinea. A big reason New Guinea has so many animals is its geography. It has everything from ridiculously high mountains with glaciers to lowland rainforests, savannas, wetlands, mangrove forests, rivers, lakes, alpine tundra, and coral reefs off the coast. About the only thing it doesn’t have is a desert. Most of the island is warm and humid with lots of rain. Of course people live in New Guinea too, and have for at least 40,000 years, possibly as long as 60,000 years. Back then, New Guinea was connected to Australia by a land bridge similar to the one that has connected North America with Asia when sea levels were low. Some of the earliest humans to migrate out of Africa settled in New Guinea, and the people there developed agriculture independently of the people who settled in the Middle East. More people arrived much later, only around 3,500 years ago, from parts of Asia. But because the land is so hard to navigate due to the mountains and rivers and so forth, people who moved to a new part of the island were largely isolated from the people in other parts. Some 7,000 languages are spoken on the island right up to the present day, with several hundred more languages once spoken. Unfortunately, as happens so often, after European explorers discovered the island in the 16th century, they decided they would like to have it for themselves. So they took it, which is just rude. The eastern half of the island is now independent as of 1975, called Papua New Guinea, while the western half, usually just called Papua, is now part of Indonesia. Indonesia is an Asian country and unfortunately, they’re being just as bad to the indigenous people of the area as Europeans were. There are still lots of places in New Guinea that scientists haven’t explored, mostly in the mountains, and undoubtedly lots and lots of animals and birds that are completely unknown to science. Some of the animals and birds of the mountains may never have been seen by any person at all. M specifically wanted us to cover bowerbirds, so let’s start with them. Bowerbirds live in Australia and New Guinea along with a few smaller islands, with twenty species known. You may have heard about them before, because a male bowerbird builds what’s called a bower and decorates it with items he selects to attract a female. A bower is a nice little shady area where you’d like to have a picnic, unless you’re a female bowerbird in which case you’d like to examine all the things a male has collected and evaluate his elaborate courtship dance. Because the female builds a nest and takes care of her eggs and chicks by herself, she’s really picky about who she mates with. She wants the strongest, healthiest male she can find so her babies will be healthy too. She looks for a male who has the energy to build a bower, collect pretty items to decorate it, and then perform an elaborate courtship dance when the female shows up. She will visit numerous bowers before she makes a decision, narrowing them down over the course of several days or even weeks until she chooses between the best candidates. Researchers think the bowerbird is most closely related to corvids, which as you may remember includes birds like crows, magpies, and jays, but they’re also closely related to birds of paradise. Some bowerbirds are plain black or brown, some are mostly black or brown with green or other colored marking

Episode 205: Sea Scorpions and the Late Ordovician Mass Extinction Event

Happy new year! This week we’ll learn about the oldest mass extinction event, some 450 million years ago, and also sea scorpions. Further reading: Coming up for air: Extinct sea scorpions could breathe out of water, fossil detective unveils Sea scorpions could get really, really big: A fossil Eurypterus: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. Hello, 2021, please be better than 2020 was. I’ve got lots of fun, interesting episodes planned for this year, but let’s start the year off right with an episode about, uh, a major extinction event. Specifically it’s the Late Ordovician mass extinction, which occurred around 450 million years ago. This is the first of a series of episodes about extinction events I have planned for this year, which I hope you’ll find interesting. We’ll also learn about an animal called the sea scorpion. If you’ve listened to episode 69, about the Cambrian explosion, you may remember that the fossil record shows that around 540 million years ago life on earth evolved from simple organisms into much more complicated ones. This happened relatively quickly in geologic terms, about 15 to 25 million years for life to go from microbial mats, simple worms, and single-celled animals to fantastical creatures with shells and spikes and novel ways of feeding as animals adapted to fit new ecological niches. But what happened after that? A series of extinction events, that’s what. The first extinction event researchers can identify from the fossil record is called the End-Botomian extinction event, which happened around 510 million years ago in two phases. We’re not sure what caused the extinctions, but the main theory is that a series of massive volcanic eruptions caused climate changes that led to acidification of the oceans and a resulting loss of oxygen from the water. This was followed by another extinction event around 500 million years ago. All told, during these ten million years or so, about 40% of all species of animal went extinct. But remember, all we have to work with is the fossil record. Researchers know how old particular rock strata are, strata being the term for layers, so when they find a fossil embedded in a rock they know roughly how long ago it lived. Only a small percentage of animals that ever live end up fossilized, and only a small percentage of fossils are ever found by humans, and only a small percentage of fossils found by humans get studied by experts. So while scientists do their best, they’re working with a limited amount of data to determine what happened half a billion years ago. It’s like trying to determine the rise and fall of empires from a series of random photographs. But when older rocks show a whole lot of fossils of various kinds, and then slightly younger rocks show way fewer or no fossils, researchers can be pretty sure that something catastrophic happened to kill off a lot of animal life in a relatively short amount of time. If they find the same changes in rocks of the same age in different parts of the world, the catastrophe was probably worldwide and serious enough to impact life on Earth for thousands or even millions of years. That’s what happened in the late Ordovician. Around 460 million years ago, about the time that life was getting back to normal after the last extinction event, glaciers started to form across the land. Most of the continents at this time were smushed together into a supercontinent called Gondwana, which was mostly in the southern hemisphere. Much of the rest of the Earth was one big ocean, and it was hot and tropical just about everywhere. But that changed when temperatures dropped drastically. Glaciers formed, sea levels fell, and some 60% of all life on Earth went extinct, all possibly within about one million years. We don’t know why, but we do have some clues and some theories. We know there was a major meteor event around 467 million years ago, which can be pinpointed because of the craters and specific minerals and bits of meteorites found that can only come from meteors hitting the earth. The impacts kicked dust into the atmosphere that then reflected sunlight back into space, causing less light to reach the earth. Another cause might have just been a cyclical movement of the Earth in space. As you hopefully know, Earth rotates on its axis in a 24 hour period, giving us day and night, and at the same time it’s moving in an elliptical orbit around the sun in a 12-month period, which of course is a year. The sun and the other planets and everything else in our solar system are also moving in space in a larger orbit, and there are other even larger orbits that our solar system is part of within our galaxy, which is moving too. With all this movement all the time, it’s not surprising that Earth’s climate is affected in very long cycles, together with the effects of the moon’s gravitational pull making the Earth’s orbit just slightly wobbly. A combination of events, including wher

I’m your host, Kate Shaw. It’s the very last week of 2020, and good riddance. Let’s kick the old year out the back door and welcome in the new year with a basket of pretty frogs. That’s right, we’ve got a frog episode this week! Let’s start with the northern leopard frog, with thanks to an anonymous reviewer who gave the podcast a really nice five-star review and only signed the review “norhern lepord frong.” I looked that frog up online to see what it looked like, and it’s so pretty, honestly, it’s just the prettiest frog! If you had a basket of northern leopard frogs, they might just look like friendly flowers, because while most are green or brown with darker spots, some are much brighter green with yellow markings, some are dark brown, and some are even pinkish white because of a rare albino trait. Its spots are outlined with yellow or light green and it has two folds of skin that run the length of the body and are sometimes yellow. These folds of skin are called dorsolateral folds and many frogs have them, although they’re not always as easy to spot as in the northern leopard frog. The northern leopard frog is native to the northern part of North America, especially southern Canada and the northern and western United States. It grows up to 4.5 inches long, or 11.5 cm, measured from snout to vent. As you may recall from previous frog episodes, that’s how frogs are always measured. It basically just means nose to butt. Females are larger than males, which is also the case for most frogs. It lives anywhere that it can find fresh water, including rivers, streams, creeks, ponds, marshes, even drainage ditches, but it prefers slow-moving or quiet water. As a result, it’s threatened by loss of habitat, pollution, and climate change, all of which affect the water it needs to live, and it’s also threatened by non-native animals and diseases. But while it doesn’t live in as many places as it used to, right now it’s doing fine overall and isn’t considered endangered. Like most frogs, the northern leopard frog eats insects and any other small animal it can swallow. It has a long sticky tongue that it can shoot out so quickly that even an insect can’t outfly it, but it doesn’t just eat insects. It’s a big frog with a big mouth, and it’s been recorded eating other species of frog, small snakes, small birds, and even a bat. But mostly it eats insects, slugs, snails, and worms. Probably the frog that was documented as catching and eating a bat is famous in the northern leopard frog world, or at least it would be if real life was like the inside of my head and frogs had their own tiny newspapers. The northern leopard frog was once considered a delicacy, with most frogs’ legs coming from this particular species. It’s also sometimes kept as a pet. It’s mostly nocturnal and semi-aquatic, sometimes called the meadow frog because it will leave the water to hunt for food in grassy areas. It hibernates in winter but is better adapted to cold weather than a lot of frogs are. There’s also a southern leopard frog that looks very similar to the northern leopard frog but lives farther south, which you probably guessed from the name. It’s also slightly larger than the northern leopard frog, up to five inches long, or 13 cm. Male leopard frogs, like many other frogs, have special vocal sacs in the throat that allow a male to make a loud call in spring to attract females. Different species of frog have different calls, naturally, and the vocal sacs are shaped differently in every species. The male leopard frog, northern and southern, has two vocal sacs that he fills with air like balloons, which amplifies the sound of his voice and makes it much louder. This is what a northern leopard frog sounds like: [frog sound] Another colorful frog is from India and was only discovered in 2010. A team of scientists surveying the mountains for reptiles and amphibians noticed a teensy frog in the leaf litter one night. Its back was brown with light blue dots that looked like stars in a night sky, but its belly was orange like a sunset. It’s a very pretty frog. The researchers caught several of the frogs and thought they were pretty but not especially unusual. There are at least 400 known frogs in India and new species are found pretty frequently. The team named it the starry dwarf frog because of the blue dots and its size, less than 20 mm long, or around half an inch. That’s about the size of an adult’s thumbnail. After the expedition, though, when the team examined the frogs more close

I’m your host, Kate Shaw. Let’s learn about some insects this week, but not just any old insects. Let’s learn about insects that swarm. Thanks to Nicholas and Juergen for suggestions that led to this episode! Nicholas suggested long-distance migrators ages ago, and I did do an episode about migration for a Patreon episode. I’ve unlocked that episode so anyone can listen to it, with a link in the show notes. I’ve also used some of the information in that episode for this one, specifically the part about monarch butterflies. In fact, let’s start with the monarch butterfly. The monarch is a good-sized butterfly, with orange and black wings with white spots along the edges and a wingspan of up to four inches, or 10 cm. It lives in many parts of the world, but only the North American subspecies of monarch migrates. Every autumn, monarch butterflies living in North America, where they breed, head south to winter in the mountains of central Mexico, a trip that can be as long as 3,000 miles, or 4,800 km. They spend the winter in oyamel fir trees, millions of butterflies in the branches. When spring arrives, the butterflies head north again, but they don’t get all the way back to their original range. If they’re lucky, they reach Texas, where they mate and lay eggs on milkweed plants before dying. The caterpillars hatch, eat up the milkweed, spin cocoons, and emerge transformed into new butterflies that continue the flight north, deeper into North America. But those butterflies don’t make it all the way to their parents’ home range either. They too stop to mate, lay eggs, and die. It can take four or five generations for monarch butterflies to reach Canada and other distant parts of North America, and by that time it’s autumn again. The butterflies fly back to Mexico. Butterflies heading north live out their entire life cycle in only five or six weeks, but the butterflies that return to Mexico live up to eight months. Researchers think the northward migration follows the blooming of milkweed plants. Milkweed contains toxins that make the monarchs poisonous to a lot of animals, but some birds and a lot of insects will eat the caterpillars. Some populations of North American monarchs overwinter in California, Arizona, or Florida instead of Mexico. The North American monarch is declining in numbers, probably mostly due to the decline of milkweed. The best way to help the butterfly is to plant milkweed in any area you don’t want to mow very often. While the monarch migration is astounding, it’s not the only butterfly that migrates. A small, pretty butterfly called the painted lady lives throughout much of the world, even the Arctic, but not South America for some reason. Some populations stay put year-round, but some migrate long distances. One population winters in tropical Africa and travels as far as the Arctic Circle during summer, a distance of 4,500 miles, or 7,200 km, which takes six generations. The butterflies who travel back to Africa fly at high altitude, unlike monarch butterflies that fly quite low to the ground most of the time. Unlike the monarch, painted ladies like many kinds of flowers, not just one plant, and they don’t always migrate every year. In Australia, some populations of the bogong moth migrate some 600 miles, or 965 km. It’s a dark brown moth with a wingspan of up to two inches across, or 5 cm, and naturally enough, it migrates at night. Unlike the butterflies we’ve talked about, the migration doesn’t take successive generations. In spring the moths fly from the lowlands into the mountains, where they spend the summer mostly hiding in caves and other dark places. The bogong moth actually breeds and lays eggs in winter, because it doesn’t like hot weather. Birds and some other animals depend on the moth migration for food, when they can eat a lot of big fat moths and get lots of protein. Some Aboriginal tribes of southeastern Australia also used to follow the migration into the mountains, where they would gather lots of moths from caves and roast them. Apparently they taste like nuts. But the insect that migrates farthest is a species of dragonfly. The globe skimmer, also called the wandering glider or winged wanderer, lives in much of the world, but not in Europe. Researchers think it can’t cross the Sahara to reach Europe, but i

Episode 202: Terror Birds and Pseudotooth Birds

Llallawavis scagliai: Big birdie! A red-legged seriema and an unfortunate snake: Another big birdie! Toothy birdie! Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This week we’re going to learn about some gigantic extinct birds! Pranav wants to hear about Phorusrhacidae, also known as the terror bird. Something called a terror bird is definitely going to be interesting. My brother Richard also tweeted me about some huge extinct birds called pelagornithids, so we’ll talk about them too. Both birds were huge and successful, but extremely different from each other. Phorusrhacidae is the name for a family of flightless birds that lived from about 62 million years ago to a little under 2 million years ago. Flightless birds may make you think of ostriches and penguins and dodos, but remember that Phorusrhacids were called terror birds. They were carnivores and many of them were enormous. Most terror birds lived in South America, with one species known from southern North America. A few newly discovered bird fossils from Africa and Europe may have been close relations of terror birds, but palaeontologists are still studying them. Various species of terror bird ranged in size from about 3 feet tall to 10 feet tall, or 1 to 3 meters, and had long, strong legs that made them fast runners. The terror bird also had a long, strong neck, a sharp hooked beak, and sharp talons on its toes. The beak was strong but the jaw muscles were relatively weak. Researchers think that it ambushed prey and chased it down, then either kicked it to death with its sharp talons or held it down with its feet and stabbed it to death with its beak. Smaller species may have grabbed its prey and thrown it back down with enough force to injure, stun, or outright kill the animal. It may have swallowed small prey whole and regurgitated pellets made up of compressed fur and bones, the way many modern carnivorous birds do today. Although the beak was strong, it was also hollow. This would have made it weigh less, which meant that the bird could move its head more quickly. Some researchers think that it might also have acted as a resonant chamber, and that the bird could clap its beak closed to make a loud noise to communicate with other terror birds. It had excellent hearing and vision, but a poor sense of smell. Many details of what we know about terror birds come from a single specimen discovered in 2010 in Argentina. The bird lived around 3 million years ago and stood four feet tall, or 1.2 meters. It was described in 2015 and is named Scaglia’s magnificent bird. I am not going to attempt to pronounce its scientific name [Llallawavis scagliai], but I’ll put it in the show notes along with a picture. Almost the entire skeleton is preserved in stunning detail, including details that hardly ever preserve, like the tiny bones that help the eye focus. Studies of the tiny ear bones and other details of the ear indicate that its hearing was most acute at low frequencies, which meant it would have been good at hearing footsteps. It also probably had a deep voice. The terror bird had wings, but they were small and probably only used for display. The wings did have claws, though, and may have been used to fight other terror birds over mates or territory. Young terror birds of some species might have been able to fly, although adults certainly couldn’t. The earliest known terror bird, Paleopsilopterus, lived about 60 million years ago in what is now Brazil. It was relatively small, only about three feet high, or 1 meter. It evolved only a few million years after the non-avian dinosaurs went extinct, and its descendants became larger and more fearsome until they were apex predators throughout South America. Kelenken, for instance, grew up to ten feet tall, or three meters, and had an enormous beak, 18 inches long or almost 46 cm. It lived in what is now Argentina around 15 mya. It’s the tallest terror bird known but it was more slenderly built than others so was probably a faster runner. It was only discovered in 1999. Brontornis, however, was the one that puts the terror into terror bird. It grew over 9 feet tall, or 2.8 meters, but it was massively built. It probably wasn’t a very fast runner and would have definitely been an ambush predator. Most likely it hid among trees or other tall vegetation, and when an animal came too close, BOOM! THERE’S A TERROR BIRD! RUN! TOO LATE, ARGH! Titanis lived in parts of North America, with fossils found in Texas and Florida. It probably stood a little over eight feet tall, or 2.5 meters, although we don’t have any complete skeletons so can only estimate its actual size compared to other species of terror bird. Y

The beautiful spiny flower mantis: The ghost mantis looks not like a ghost but a dead leaf: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This week we’re going to look at two completely unrelated animals, but both are really interesting. Thanks to Page and Viola for the suggestions! We’ll start with Page’s suggestion, the African gray parrot. We haven’t talked about very many parrots in previous episodes, even though parrots are awesome. The African gray parrot is from Africa, and it’s mostly gray, and it is a parrot. Specifically it’s from what’s called equatorial Africa, which means it lives in the middle of the continent nearest the equator, in rainforests. It has a wingspan of up to 20 inches, or 52 cm, and it has red tail feathers. The African gray parrot is a popular pet because it’s really good at learning how to talk. It doesn’t just imitate speech, it imitates various noises it hears too. It’s also one of the most intelligent parrots known. Some studies indicate it may have the same cognitive abilities as a five year old child, including the ability to do simple addition. It will also give its treats to other parrots it likes even if it has to go without a treat as a result, and it will share food with other parrots it doesn’t even know. Despite all the studies about the African grey in captivity, we don’t know much about it in the wild. Like other parrots, it’s a highly social bird. It mostly eats fruit, seeds, and nuts, but will also eat some insects, snails, flowers, and other plant parts. It mates for life and builds its nest in a tree cavity. Both parents help feed the babies. That’s basically all we know. It’s endangered in the wild due to habitat loss, hunting, and capture for sale as pets, so if you want to adopt an African grey parrot, make sure you buy from a reputable parrot breeder who doesn’t buy wild birds. For every wild parrot that’s sold as a pet, probably a dozen died after being taken from the wild. A good breeder will also only sell healthy birds, and will make sure you understand how to properly take care of a parrot. Since the African grey can live to be up to sixty years old, ideally it will be your buddy for basically the rest of your life, but it will require a lot of interaction and care to stay happy and healthy. One African grey parrot named Alex was famous for his ability to speak. Animal psychologist Dr. Irene Pepperberg bought Alex at a pet shop in 1977 when he was about one year old, not just because she thought parrots were neat and wanted a pet parrot, but because she wanted to study language ability in parrots. Pepperberg taught Alex to speak and to perform simple tasks to assess his cognitive abilities. Back then, scientists didn’t realize parrots and other birds were intelligent. They thought an animal needed a specific set of traits to display intelligence, such as a big brain and hands. You know, things that humans and apes have, but most animals don’t. Pepperberg’s studies of Alex and other parrots proved that intelligence isn’t limited to animals that are similar to us. Alex had a vocabulary of about 100 words, which is average for a parrot, but instead of just mimicking sounds, he seemed to understand what the words meant. He even combined words in new ways. He combined the words banana and cherry into the word banerry to describe an apple. He didn’t know the word for cake, so when someone brought a birthday cake into the lab and he got to taste it, he called it yummy bread. When he saw himself in a mirror for the first time, he said, “What color?” because he didn’t know the word gray. He also asked questions about new items he saw. So not only did he understand what words meant, he actually used them to communicate with humans. As Pepperberg explains, Alex wasn’t super-intelligent or unusual for a parrot. He was just an ordinary parrot, but was trained properly so he could express in words the intelligence that an average parrot uses every day to find food and live in a social environment. Alex died unexpectedly in 2007 at only 31 years old. I’ve put a link in the show notes to a really lovely Nova Science Now segment about Alex and Dr. Pepperberg, and some other videos of Alex and other parrots. Pepperberg has continued to work with other parrots

Episode 200: Elephants

This week we’re going to learn about elephants! Thanks to Damian, Pranav, and Richard from NC for the suggestions!

I’m your host, Kate Shaw. This week we’re going to learn about some elephants! We’ve talked about elephants many times before, but not recently, and we’ve not really gone into detail about living elephants. Thanks to Damian, Pranav, and Richard from NC for the suggestions. Damian in particular sent this suggestion to me so long ago that he’s probably stopped listening, probably because he’s grown up and graduated from college and started a family and probably his kids are now in college too, it’s been so long. Okay, it hasn’t been that long. It just feels like it. Sorry I took so long to get to your suggestion. Anyway, Damian wanted to hear about African and Asian elephants, so we’ll start there. Those are the elephants still living today, and honestly, we are so lucky to have them in the world! If you’ve ever wished you could see a live mammoth, as I often have, thank your lucky stars that you can still see an elephant. Elephants are in the family Elephantidae, which includes both living elephants and their extinct close relations. Living elephants include the Asian elephant and the African elephant, with two subspecies, the African savanna elephant and the African forest elephant. The savanna elephant is the largest. The tallest elephant ever measured was a male African elephant who stood 13 feet high at the shoulder, or just under 4 meters, which is just ridiculously tall. That’s two Michael Jordans standing on top of each other, and I don’t know how you would clone Michael Jordan or get one of them to balance on the other’s head, but if you did, they would be the same size as this one huge elephant. The largest Asian elephant ever measured was a male who stood 11.3 feet tall, or 3.43 meters. Generally, though, it’s hard to measure how tall or heavy a wild elephant is because first of all they don’t usually want anything to do with humans, and second, where are you going to get a scale big and strong enough to weigh an elephant? Most male African elephants are closer to 11 feet tall, or 3.3 meters, while females are smaller, and the average male Asian elephant is around 9 feet tall, or 2.75 meters, and females are also smaller. Even a small elephant is massive, though. Because of its size, the elephant can’t jump or run, but it can move pretty darn fast even so, up to 16 mph, or 25 km/h. The fastest human ever measured was Usain Bolt, who can run 28 mph, or 45 km/h, but only for very short distances. A more average running speed for a person in good condition is about 6 mph, or 9.6 km/h, and again, that’s just for short sprints. So the elephant can really hustle. Its big feet are cushioned on the bottoms so that it can actually move almost noiselessly. And I know you’re wondering it, so yes, an elephant could probably be a good ninja if it wanted to. It would have to carry its sword in its trunk, though. The elephant is also a really good swimmer, surprisingly, and it can use its trunk as a snorkel when it’s underwater. It likes to spend time in the water, which keeps it cool, and it will wallow in mud when it can. The mud helps protect it from the sun and from insect bites. Its skin is thick but it’s also sensitive, and it doesn’t have a lot of hair to protect it. The elephant is a herbivore that only eats plants, but it eats a lot of them. An adult elephant eats several hundred pounds of food a day, or more than 100 kg, and will drink enough water every day to fill a bathtub. It eats grass, leaves, twigs, fruit, and bark, and elephants in captivity also eat hay. And since we’re getting close to the winter holidays, some zoos have an agreement with Christmas tree sellers, who donate any unsold Christmas trees to the zoos for the elephants to eat. They can’t feed used trees because there might be leftover ornaments or ornament hangers on them. The elephant just puts one foot on the tree and rips off the branches with its trunk, which it then eats. The elephant has a pair of big teeth on each side of its mouth that look more like the bottoms of running shoes than ordinary teeth, which it uses to grind up the tough plants it eats. Elephants technically have 26 teeth, two incisors and 24 molars. The incisors are modified into tusks, which we’ll talk about in a minute. The molars aren’t all in the mouth at once, though. Every so many years, the four molars in an elephant’s mouth start to get pushed out by four new

Episode 199: Carnivorous Sponges!

Thanks to Lorenzo for this week’s topic, carnivorous sponges! How can a sponge catch and eat animals? What is its connection to the mystery of the Eltanin Antenna? Let’s find out!

I’m your host, Kate Shaw. This week we’re going to learn about carnivorous sponges, which is a suggestion from Lorenzo. When I got Lorenzo’s email, I thought “oh, neat” and added carnivorous sponges to the giant, complicated list I keep of topic suggestions from listeners and my Aunt Janice, and also animals I want to learn more about. When I noticed carnivorous sponges on the list the other day, I thought, “Wait, sponges are filter feeders. Are there even any carnivorous ones?” The answer is yes! Most sponges are filter feeders, sure, but there’s a family of sponges that are actually carnivorous. Caldorhizidae is the family, and it’s made up of deep-sea sponges that have only been discovered recently. We know there are lots more species out there because scientists have seen them during deep-sea rover expeditions without being able to study them closely. We talked about sponges way back in episode 41, with some mentions of them in episodes 64 and 168 too, but only the filter feeder kind. Let’s first learn how a filter feeder sponge eats, specifically members of the class Demosponge, since that’s the class that the family Caldorhizidae belongs to. Sponges have been around for more than half a billion years, since the Cambrian period and possibly before, and they’re still going strong. Early on, sponges evolved a simple but effective body plan and just stuck to it. Of course there are lots and lots and lots of different species with different shapes and sizes, but they almost all work the same way. Most have a skeleton, but not the kind of skeleton that you think of as an actual skeleton. They don’t have bones. The skeleton is usually made of calcium carbonate and forms a sort of dense net that’s covered with soft body tissues. The tissues are often further strengthened with small pointy structures called spicules. If you’ve ever played a game called jacks, where you bounce a ball and pick up little metal pieces between each bounce, spicules sort of resemble jacks. The sponge has lots of open pores in the outside of its body, which generally just resembles a sack or sometimes a tube. One end of the sack is attached to the bottom of the ocean, or a rock or something. The pores are lined with cells that each have a teensy structure called a flagellum, which is sort of like a tiny tail. The sponge pumps water through the pores by beating those flagella. Water flows into the sponge’s tissues, which are made up of lots of tiny connected chambers. Cells in the walls of these chambers filter out particles of food from the water, much of it microscopic, and release any waste material. The sponge doesn’t have a stomach or any kind of digestive tract, though. The cells process the food individually and pass on any extra nutrients to adjoining cells. Obviously, this body plan is really effective for filter feeding, not so effective for chasing and killing small animals to eat. The sponge you may have in your kitchen is probably synthetic or manufactured from a sponge gourd, not an actual bath sponge animal, but it’s arranged the same way. Go look at that sponge, or just imagine it, and then compare it mentally to, say, a tiger. Very different. But in 2007, an underwater rover captured something on film that astounded researchers. The rover was investigating some undersea caves in the Mediterranean, where a tiny sponge known as Asbestopluma hypogea lives. The sponge only grows about half an inch long, or 1.5 cm, and everyone assumed it was just a regular old sponge. You know, a filter feeder. It did have an unusual structure of filaments covered with hook-like spicules, but until 2007 no one realized those spicules were actually hooks and used to snag tiny animals like copepods, nematodes, and even brittle stars. Then they saw it on film and freaked out! Well, they probably freaked out. I like to think they did. But wait, you are probably saying, or at least thinking, sponges don’t even have a digestive system! How do they eat the animals they catch? It works like this. When a tiny animal floats or swims past and gets snagged by the hooked spicules, which by the way is a passive process, the sponge starts growing a membrane that envelops the anim

Episode 198: Pop Goes the Mustelid

Let’s learn about a whole lot of mustelids, including some otters, weasels, and their relations and ancestors! Thanks to Jacob for the suggestion! Further reading: Weasels in Stone: Mustelid Evolution With voices joined in chorus, giant otter families create a distinct sound signature Further watching/listening: Video of giant river otters making noise Giant river otters: The least weasel is possibly the most cute: This mink would like to keep its fur for itself please and thank you: The Patagonian weasel: The greater grison looks like a badger and a honey badger: The fisher: The Chinese ferret badger has a long nose compared to most mustelids: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This week we’ll learn about some mustelids, better known as weasels and their close relations! Thanks to Jacob for this week’s suggestion. The weasel is a member of the family Mustelidae. Members of the family are called mustelids, which includes wolverines and badgers, which we talked about in episode 62, otters, which we talked about in episode 37, and ferrets, which we talked about in episode 150. Most mustelids have short legs and long, slender, flexible bodies, although badgers are an exception since they’re broad-bodied. This body shape allows a mustelid to enter the burrows of other animals and kill them, because mustelids are carnivores. But not all animals that look like weasels and ferrets are actually mustelids. The mongoose, for instance, is not a mustelid. The study of how mustelids evolved and spread throughout much of the world is a pretty hot topic these days, which makes it confusing to summarize since so much new knowledge keeps shaking up what we know. But I’ll do my best. The first mustelids evolved around 30 million years ago in what is now Eurasia, and spread to North America much later and eventually into South America. The oldest mustelid fossils found in North America are a group of animals called oligobunines. I read that word as oligobunnies every single time, but they didn’t look like bunnies. They probably looked like wolverines, which are related to badgers but look more like miniature bears with longer tails, but they probably spent more time underground than wolverines do. At least one oligobunid might have grown as big as a black bear, at least a small bear. Megalictis was probably an ambush predator and lived around 21 million years ago in what is now the upper Midwest of North America. It had teeth meant for crushing bones. Another oligobunid, Zodiolestes, is one we talked about briefly in episode 103, about trace fossils. The first fossil Zodiolestes was found in a corkscrew-shaped Palaeocastor burrow, presumably because it got stuck in the burrow while it was hunting, but Zodiolestes was also adapted to dig. The oligobunids went extinct around 10 million years ago, possibly outcompeted by a new wave of modern mustelids that evolved in Asia and spread into North America. One mustelid, Ekorus ekakeran, lived about six million years ago in what is now Africa, with fossils found in Kenya. But it didn’t look like any other mustelid. It had long legs, for one thing. It stood almost two feet tall at the shoulder, or 60 cm, and was built more like a leopard than a mustelid. It would have been a much faster runner than other mustelids as a result, although it was probably an ambush predator. Researchers think it was eventually outcompeted by big cats when they evolved as the forests changed into grasslands. The biggest mustelid that ever lived, as far as we know, is Enhydriodon, a type of gigantic otter. It lived in Africa around 4 million years ago and may have been the size of a small bear, even bigger and heavier than Megalictis. We only have a single fossil of Enhydriodon, though, a skull, so scientists can only estimate the animal’s size compared to what we know about extinct and living otters. It probably lived on land, although that’s about as far as our knowledge of it goes. Another giant mustelid was Plesiogulo, which evolved in Asia and crossed into North America 6 1/2 or 7 million years ago when the continents were connected by the Bering land bridge. Researchers weren’t sure for a long time if Plesiogulo was directly ancestral to living wolverines, but recent studies indicate that it probably was. It was larger than modern wolverines. But what about living mustelids? The biggest known mustelid that’s still alive is the giant otter, which lives in much of northern and central South America, especially around the Amazon River, although it’s increasingly rare due to habitat loss, hunting for its fur, and pollution. It can grow up to 5 1/2 feet long, or 1.7 meters. It mostly eats fish but will eat other animals too, including crabs, snakes, turtles, and even small caimans. It’s a social animal that lives in family groups of up to twenty members that hunt and play together. It has short dense fur that’s usually brown or sometimes reddish, but it has

I’m your host, Kate Shaw. This has been a really busy week for me and I wasn’t able to finish researching the episode I had planned. Instead, we’ll have a short episode on a topic Pranav suggested ages ago, TITANOBOA! In September 2017 I released a Patreon episode about giant snakes, including Titanoboa, but this episode is all new. Ha ha, I thought it would take me less time to research it than finishing the research for what will be next week’s episode, ha ha I was wrong. Anyway, I’m going to unlock the giant snakes Patreon episode so anyone can listen. There’s a link in the show notes if you want to click through and listen on your browser. Oh, a big congratulations to the winner of my book giveaway, Arthina! Thanks to everyone who entered. In 1994, a geologist named Henry Garcia found an unusual-looking fossil in northeastern Colombia in South America. Specifically, it was an area that had been strip-mined for coal. Fifty-eight million years ago the region was a hot, swampy, tropical forest along the edge of a shallow sea. The Andes Mountains hadn’t yet formed. The environment was probably most similar to the Everglades and the Mississippi River delta in North America, but the climate was much warmer than it is now. These days what was once swamp is a field of rock uncovered by coal mining, which is not good for the environment but is unbelievably good for palaeontology. Garcia thought he’d found a piece of fossilized tree. The coal company in charge of the mine displayed it in their office along with other fossils. And there it sat until 2003, when palaeontologists arranged an expedition to the mine to look for fossil plants. A researcher named Scott Wing was invited to join the team, and while he was there he poked around among the fossils displayed by the mining company. The second he saw the so-called petrified branch he knew it wasn’t a plant. He sent photos to a colleague who said it looked like the jawbone of a land animal, probably something new to science. In 2007, the fossil was sent for study, labeled as a crocodile bone. But the palaeontologists who examined the fossil in person immediately realized it wasn’t from a crocodile. It was a snake vertebra—but so enormous that they couldn’t believe their eyes. They immediately arranged an expedition to search for more of them, and they found them! Comparisons to living anacondas and boas, the snake’s closest living relatives, helped researchers estimate the snake’s size. They named it Titanoboa cerrejonensis and described it in an article published in 2009 in Nature. In 2012, a partial Titanoboa skull was found. Snake skulls are fragile and don’t fossilize nearly as often as the more robust vertebrae and ribs. It turned out that Titanoboa had lots and lots of teeth, more teeth than modern boids have. Palaeontologists have found fossilized remains from around 30 individual snakes, including young ones. The adult size is estimated to be 42 feet, or 13 meters. The largest living snakes are anacondas, which may grow up to 29 feet, or 8.8 meters, but which are usually less than half that length. Reticulated pythons grow up to about 26 feet, or almost 8 meters, and possibly longer, but are also usually less than half that. Titanoboa might have grown up to 50 feet long, or 15 meters, and could weigh more than 2,500 pounds. That’s one and a quarter tons, or more than 1100 kg. The thickest part of its body would have been waist-high compared to an average human male. Of course, these are all estimations since we don’t have a complete skeleton or a living specimen to examine, and most estimates these days put the maximum length at around 42 feet, or 13 meters. Still humongous. Females were probably larger than males, as is the case with most snakes. Once the skull was found containing all those little teeth, researchers determined that Titanoboa probably ate a lot of fish. That’s unusual for constrictors, but it makes sense to think that a snake that large, living in a hot, tropical area, would spend most of its time in the water. Even though snakes are cold-blooded, which means their internal temperature fluctuates with the temperature of their environment, a snake that size would retain a lot of heat and even generate heat from metabolic processes. Metabolic processes are related to digestion, chemical reactions that break down food into nutrients that can be used by the body. This releases heat, and in an animal with a bulky body that heat is retained more than in an animal w

One of the “blue monkey” wall frescos and some grey langurs: The fluffy titi monkey: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. Halloween is over for another year, but that doesn’t mean things get boring. This week let’s learn about some monkeys, including a few monkey mysteries that were solved with science! Thanks to Nick and Richard for their suggestions. We’ll start with the Dracula monkey, suggested by Richard from North Carolina, who also sent me an article a while back about the monkey. I meant to include this topic in an episode before October but got distracted by all the other awesome animals that have been suggested lately. The Dracula monkey is also called Miller’s Grizzled langur, but that’s a mouthful and Dracula monkey is funnier. It’s not called the Dracula monkey because it has fangs, but because its body is gray with a white ruff that sticks out on either side of the neck like the collar of Dracula’s cape in the movies. Its face is also gray except for a white U-shaped marking under its nose like a little white mustache. It grows up to 22 inches long, or 56 cm, not counting its tail which is even longer than its body. The Dracula monkey eats young leaves and unripe fruit, along with flowers, seeds, and sometimes eggs. It spends most of its time in trees and is endangered by habitat loss and hunting, and it only lives in one place, in rainforests on the island of Borneo in South Asia. It was spotted by scientists in 2012 after it was suspected to be extinct, but that was the last anyone saw of it for years. An Animal Planet show called “Extinct or Alive” was filming in Borneo in spring of 2019, unless it was 2018, it’s not clear from the article, searching for the Dracula monkey. The host and his team set up camera traps in the forest, braving literally hundreds of bee stings as they did so. But it worked, catching the monkey on camera and proving it wasn’t extinct. When an animal is declared extinct, conservationists lose funding to help it and it’s removed from the list of protected animals, so it’s important to search for animals that are suspected to be extinct but might not be. While I was researching the Dracula monkey, I learned about a rare orchid called the Dracula monkey orchid. It has fuzzy reddish-brown and white flowers that look remarkably like a monkey’s face. It doesn’t actually look like Dracula or a Dracula monkey, though. Who names these organisms? In this case, scientists. The orchid’s scientific name is Dracula simia, and the genus Dracula is named because some of the orchids in the genus are red or black and white and the long spurs supposedly hang down like fangs. The Dracula monkey orchid is found in southeastern Ecuador in South America, and only grows in moist high-altitude forests. The flowers smell like oranges. This has been your bonus plant fact of the week. The Dracula monkey orchid actually looks more like a capuchin monkey than a Dracula monkey, so let’s learn about the capuchin next. You probably know what the capuchin monkey looks like because it’s so common in movies. The monkey in Raiders of the Lost Ark (you know, the “bad dates” monkey) was a capuchin, but the noises he makes in the movie are actually voiced by a human actor named Frank Welker. Welker also voiced the monkey Abu in Disney’s Aladdin from 1992. In the live-action remake from 2019, he’s still a capuchin but computer-animated. The capuchin monkey lives in forests in Central and South America, but there are lots of species. Most are dark brown with cream-colored markings on the face and around the neck. It lives in trees and unlike many monkeys, it’s an omnivore. It eats leaves, fruit, nuts, flowers, and other plant parts, but it also eats insects, frogs, crabs, shellfish, and other small animals. It’s about the same size as the Dracula monkey, up to 22 inches long, or 56 cm, with a tail the same length as the body. The reason so many capuchin monkeys are used in movies and TV shows is because they’re one of the most intelligent monkeys known, social, adaptable, and easy to train. But they’re wild animals and they don’t make great pets. They can be dangerous if they’re upset, and to be happy they need the company of other capuchin monkeys in a situation as much like their social structure in the wild as possible. In the wild, the capuchin lives in groups of up to 35 individuals that travel around the grou

Episode 195: Black Dogs and Mystery Canids

It’s almost Halloween!! Our Halloween episode this year is all about some of the legends of ghostly black dogs in the UK and some other parts of the world, as well as some canid mysteries we haven’t covered before. Thanks again to Pranav for the suggestion! This is your last chance to enter the book giveaway! You have until October 31, 2020, and that night at midnight (my time, Eastern daylight savings, or more likely when I wake up on November 1) I will randomly draw a name from all the people who have entered. To enter, just send me a message by email or Twitter or Facebook, or some other way. The contest is open to anyone in the world and if you win I’ll send you a signed copy of my books Skytown and Skyway, along with stickers and other fun stuff! I will mention that I haven’t actually received that many entries so you have a good chance of winning. The pages I mentioned in this episode: Books I’ve Written, List of Animals, List of Cryptids, My Wishlist Page with Mailing Address I’ve unlocked a few Patreon episodes for anyone to listen to, no login required: The Horse-Eel The Hook Island Sea Monster The Minnesota Iceman Further reading: Shuckland Trailing the Hounds of Hell – Black Dogs, Wish Hounds, and Other Canine Phantasms The Lore and Legend of the Black Dog The Mystery of North America’s Black Wolves The Beast of Bungay according to the artist employed by Abraham Fleming (left) and the church door that supposedly shows burnt scratch marks from the beast’s claws (right): A short-eared dog AKA the ghost dog: A Himalayan wolf: A dhole, closest relation to the “ghost population” of extinct canids: A black wolf (photo by Andy Skillen, and I got it from the black wolf article linked to above): Show Transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. It’s finally Halloween, and we have an episode that’s as spooky as it gets. It’s also a little unusual, because we’re going to learn about a folklore animal called the black dog, which isn’t a real dog or a real animal. But we’ll also learn about some canid mysteries we haven’t covered before, especially some mysteries associated with wolves. This is a suggestion from Pranav, who wanted to hear about more mystery canids after episode 80. As always before our Halloween episode, let’s take care of some housekeeping. First, I’ve unlocked some Patreon episodes for anyone to listen to. The links are in the show notes and you can click through and listen on your browser, no login required. This time we have episodes about the horse-eel, the Hook Island Sea Monster, and the Minnesota Iceman. Next, you still have a few days left to enter the book giveaway! This is for one paperback copy each of my books Skytown and Skyway. Skytown is a fun fantasy adventure book about two young women who steal an airship and decide to become airship pirates. As you do. Skyway is about the same characters but it’s a collection of short stories, mostly set before the events of the book. The short story collection is probably about a PG rating, for parental guidance needed, while the novel is probably more PG-13, where it’s really not for people under 13 years old. To enter the giveaway, just send me a message saying you’d like to enter. At midnight on Halloween night I will draw one winner randomly and send them the books as well as stickers, bookmarks, and some other stuff, but let’s be honest, I’m probably going to forget and fall asleep, so if any entries come in overnight on Halloween I’ll add them to the list before drawing a winner on the morning of November 1. There’s a page on the website with links to the Goodreads profiles of both books if you want to take a closer look and maybe order copies, because small publishers are really hurting right now and they could use your help. This is also a good time to remind you that there are a few other pages on the website you might want to take a look at. One has a list of animals we’ve covered on the podcast and which episodes they appear in, and another is a list of just the cryptids we’ve covered on the podcast and which episodes they appear in. The cryptids list also includes Patreon episodes, including links to unlocked episodes, so if you’re new to the show and really want more mystery animal content, you might browse through that page. There’s also a contact information page that contains a link to my book wishlist if you’re feeling generous and want to send me a book I’ve been looking for. Used books are fine, and I totally do not want anyone to spend a lot of money on me so don’t feel like you have to do this. Eventually I’ll buy them all for myself. My mailing address is on that page too and I would be delighted if you want to send me an animal drawing or a letter. I’ll write you back and send you a sticker. Oh, and if you just want a sticker, you can always email or message me and ask for one. Don’t forget to give me your mailing address.

I’m your host, Kate Shaw. It’s almost Halloween and I’m really excited, because we’re going to talk about a spooky encounter with a mystery creature called the Dover Demon. It’s a suggestion by Pranav that seemed perfect for monster month. First, though, I was a guest cohost on Varmints! podcast again last week, and we talked about ticks! It’s a really funny episode so you should totally go listen to it. I’ve put a link in the show notes. You really should subscribe to the podcast, though, because all the episodes are fun and informative! Dover, Massachusetts is a small town in northeastern North America, only about 15 miles from the city of Boston. Currently just over 6,000 people live there, up from about 5,000 people in 1977. It’s an affluent town with good schools, a small museum, and a number of historic homes. But it’s most well known for something weird that happened over forty years ago. On the night of April 21, 1977, three seventeen-year-old boys were driving along Farm Street on the outskirts of town. Bill Bartlett was driving with his friends Mike and Andy in the car with him. This was long before the internet or video games or even cable TV were invented, so they were just driving around and talking since they had nothing better to do. It was a Thursday night and cooling down after an unusually warm day for late April in that part of North America. Around 10:30pm, as they passed along a low stone wall on the left side of the road, Bill noticed an animal of some kind climbing on the stones. He thought it was a dog or even a cat at first, but then the car’s headlights lit it up. Bill saw the creature turn its head and stare into the light. The creature was definitely not a dog. It had big round eyes that shone like orange marbles, as Bill described it later. He estimated it would have been four feet tall if it had been standing upright, or 122 cm. It had peach-colored skin that looked like it might have a rough texture, which Bill later described as looking like wet sandpaper or a shark’s skin. Its body was thin, its arms and legs were very long and thin, and it had a thin neck. But its head was oversized and oddly shaped. Bill described it as shaped like a melon, but to me it always sounds more like Snoopy the dog’s head. You know, Snoopy has a round head and a big oblong nose in comparison to a little body. But this creature wasn’t a cartoon character, it was real. Bill said it had long, thin fingers and toes that it wrapped around the rocks as it climbed over them. But while it did have those big glowing eyes, it didn’t appear to have ears, nose, or mouth. The other two boys in the car were talking and didn’t notice the creature as the car passed it going somewhere around 45 mph, or 72 km/h. Bill was naturally freaked out and after about three quarters of a mile, or a little over a km, he stopped the car to tell his friends what he’d seen. They talked it over for a good 15 minutes before deciding to turn around and go back to look for the creature. But they didn’t see it again, so Bill dropped his friends off at their homes, then went home himself. Bill’s father noticed that he seemed upset and Bill admitted that he’d seen something that had spooked him. He made a drawing of the creature and later made another drawing and a watercolor of it. Bill was a good artist and in fact when he grew up he became a professional artist. Photos of his drawings of the creature are in the show notes. A few hours later that same night, at about 12:30 AM, another boy, fifteen-year-old John Baxter, was walking home from his girlfriend’s house on Miller Hill Road. Miller Hill Road intersects Farm Street, the road where Bill saw the creature, and John was about a quarter mile, or .4 km, away from where the two roads met when he noticed another person on the road ahead. He noticed the figure’s large head and thought it was a friend who lived nearby,

Episode 193: Beebe’s Mystery Deep-Sea Fish

This week we’ll learn about five mystery fish that William Beebe spotted from his bathysphere in the early 1930s…and which have never been seen again. Thanks to Page for suggesting deep-sea fish! Further reading: How some superblack fish disappear into the darkness of the deep sea The Fine Art of Exploration Further listening: 99% Invisible “Bathysphere” The Gulper Eel unlocked patreon episode These two guys crammed themselves into that little bathysphere together.

Close-up of the extraordinary jaws (seen from underneath) is on the right: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This week we’re going to descend metaphorically into the depths of the ocean and learn about some mystery fish spotted once from a bathysphere by famous naturalist William Beebe and never seen again. Deep-sea fish is a suggestion by Page, so thank you, Page, for a fascinating and creepy addition to monster month. William Beebe was an American naturalist born in 1877 who lived until 1962, which is amazing considering he made repeated dives into the deep sea in the very first bathysphere in the early 1930s. We talked about bathyspheres way back in episode 27–you know, the one where I scream about them imploding and kind of freak out a little. Even today descending into the deep sea is dangerous, and a hundred years ago it was way way way more dangerous. Beebe was an early conservationist who urged other scientists to stop shooting so many animals. Back then if you wanted to study an animal, you just went out and killed as many of them as you could find. Beebe pointed out the obvious, that this was wasteful and didn’t provide nearly as much information as careful observation of living animals in the wild. He also pioneered the study of ecosystems, how animals fit into their environment and interact with it and each other. While Beebe mostly studied birds, he was also interested in underwater animals. Really, he seems to have been interested in everything. He studied birds all over the world, was a good taxidermist, and especially liked to study ocean life by dredging small animals up from the bottom and examining them. He survived a plane crash, was nearly killed by an erupting volcano he was observing, and fought in WWI. Once when he broke his leg during an expedition and had to remain immobilized, he had his bed carried outside every day so he could make observations of the local animals as they grew used to his presence. In the 1920s, during an expedition to the Galapagos Islands, he started studying marine animals more closely. First he just dangled from a rope over the surface of the ocean, which was attached to a ship’s boom, but eventually he tried using a diving helmet. This was so successful that he started thinking about building a vessel that could withstand the pressures of the deep sea. With the help of engineer Otis Barton, the world’s first bathysphere was invented and Barton and Beebe conducted dozens of descents in Bermuda, especially off the coast of Nonsuch Island. The bathysphere had two little windows and a single light that shone through one of the windows, illuminating the outside just enough to see fish and other animals. The bathysphere couldn’t descend all that deeply, although it set records repeatedly. The deepest they descended was 3,028 feet, or 923 meters, but Beebe made careful notes of all the animals he observed and published many articles and books about them. Many of these articles and books were illustrated by an artist named Else Bostelmann, who worked closely with Beebe and his team of scientists. Bostelmann even painted underwater while wearing a diving helmet, because she needed to know how colors were affected by underwater light. She used oil paints, since oil and water don’t mix so the paints wouldn’t wash away, and she tied strings to her paintbrushes so they wouldn’t float off. Incidentally, if you’re interested in reading a really interesting article about Bostelmann or learning more about the bathysphere and William Beebe, check the show notes. I’ve included links to the article and to a 99% Invisible episode about the bathysphere. Many of the animals Beebe saw from the bathysphere have since been identified and described by later scientists. But there are five fish that Beebe observed that have never been

I’m your host, Kate Shaw. It’s finally October, which means it’s monster month on the podcast! Let’s jump right in with an episode about three animals with the word ghost in their name, and some spooky ghost stories that feature animals. (Don’t worry, they won’t be too spooky. I don’t want to scare myself.) First up is my personal favorite, the ghost bat. That’s, like, twice the Halloween fun in one animal! Not only that, it’s a member of a family of bats called false vampires, and is sometimes called the Australian false vampire bat. I am just, I can’t, this bat is too perfect and I have died. The ghost bat lives in parts of northern Australia and is actually pretty big for a microbat. Its wingspan is almost 20 inches wide, or 50 cm. Its color is pale gray, sometimes almost white, while babies are darker gray. It has large, long ears and a nose leaf that helps it echolocate, and it’s nocturnal like most microbats. While it doesn’t have a tail, it does have sharp teeth and a strong jaw to help it eat even the bones of small animals. Most microbats eat insects, but the ghost bat prefers vertebrates like frogs, mice, snakes, lizards, birds, even other species of bat. It hunts by dropping down on its prey, most of which live on the ground. It folds its wings around its prey and bites it in the neck to kill it, which makes it even better as a Halloween bat. I love this bat. It eats almost all of the body of its prey, including fur, bones, teeth, and even small feathers in the case of birds. Sometimes it eats its prey immediately, but sometimes it carries it to a small cave to eat, separate from its roosting area, referred to as a midden since the floor is littered with the remains of past meals. If you’re not familiar with the word midden, it just means a trash heap. Researchers love finding a ghost bat’s midden because they can find out exactly what animals the bat has eaten lately. Female ghost bats roost in groups during the late spring to have their babies, usually in caves or abandoned mines. A female gives birth to a single baby, and she carries it around until it’s big enough to learn how to fly on its own, in about seven weeks. Once it can fly, it accompanies its mother on hunting trips until it’s fully weaned several months later. A mother bat has two pairs of teats, one pair near her armpits that produces milk for her baby to drink, and one pair near her legs that doesn’t produce milk. The teats near her legs act as little handholds for her baby to help it keep a good grip on her, especially when it’s very young. The ghost bat is vulnerable to many of the usual concerns, including habitat loss and introduced predators, but it also has an unusual issue with an introduced plant and a type of fencing. The ghost bat doesn’t fly very high most of the time, since it’s usually hunting for small animals that live on the ground or birds roosting in bushes. As a result, its wings frequently get snagged on the spines of a thorny plant called lantana, and on barbed wire fencing. The spines or barbs tear the wings’ delicate patagia, often so badly that the bat can’t fly and starves to death. Since there are only an estimated 8,000 of the bats left in the wild, this is especially bad. The ghost bat has good hearing, naturally, but it also has good eyesight. It uses a combination of hearing, vision, and echolocation to navigate and find prey. It also makes some sounds within the hearing range of humans. This is what a ghost bat sounds like: [ghost bat chattering] That bat sounds adorable and not spooky at all. So let’s bump up the spooky factor with our first ghost story. This one comes from one of my favorite books, The Telltale Lilac Bush by Ruth Ann Musick, which we talked about in episode 91, about spooky owls. It’s a collection of ghost stories collected by folklorists in West Virginia. This story is called “A Loyal Dog.” “Many years ago a small boy saw a little dog floating down the river on a log. He swam out, rescued the dog, and took it home with him. After this, the boy and the dog were together at all times. The dog lived for almost twenty years, and when it died, the young man was very sad to see his good friend go. “Sometime later the young man was walking through a field, when all at once he wa

I’m your host, Kate Shaw. This week let’s look at some masters of disguise. This is a suggestion from Nicholas, but we’ll also learn about how octopuses and other animals change colors, which is a suggestion from Pranav. Both these suggestions are really old ones, so I’m sorry I took so long to get to them. A couple of years ago we had a Patreon episode about animal mimics, so I’ll be incorporating parts of that episode into this one, but if you want to listen to the original Patreon animal mimics episode, it’s unlocked so anyone can listen to it. I’ll put a link to it in the show notes. Most animals are camouflaged to some degree so that they blend in with their surroundings, which is also called cryptic coloration. Think about sparrows as an example. Most sparrows are sort of brownish with streaks of black or white, which helps hide them in the grass and bushes where they forage. Disruptive coloration is a type of camouflage that breaks up the outlines of an animal’s body, making it hard for another animal to recognize it against the background. Many animals have black eye streaks or face masks that help hide the eyes, which in turn helps hide where their head is. But some animals take camouflage to the extreme! Let’s learn about some of these masters of disguise. We’ll start with a bird. There’s a bird that lives in parts of South America called the cinereous mourner that as an adult is a pretty ordinary-looking songbird. It’s gray with cinnamon wing bars and an orange spot on each side. It mostly lives in the tropics. In 2012, researchers in the area found a cinereous mourner nest with newly hatched chicks. The chicks were orangey-yellow with dark speckles and had long feather barbs tipped with white. While the researchers were measuring the chicks and making observations, they noticed something odd. The chicks started moving their heads back and forth slowly. If you’ve ever seen a caterpillar moving its head back and forth, you’d recognize the chicks’ movements. And, as it happens, in the same areas of South America, there’s a large toxic caterpillar that’s fluffy and orange with black and white speckles. It’s rare that a bird will mimic an insect, but mimicry in general is common in nature. We’ve talked about some animal mimics in earlier episodes, including the orchid mantis in episode 187 that looks so much like a flower that butterflies sometimes land on it…and then get eaten. Stick insects, also known as phasmids, which we talked about in episode 93, look like sticks. Sometimes the name just fits, you know? Some species of moth actually look like bird poop. Wait, what? Yes indeed, some moths look just like bird poop. The beautiful wood nymph (that’s its full name; I mean, it is beautiful, but it’s actually called the beautiful wood nymph) is a lovely little moth that lives in eastern North America. It has a wingspan of 1.8 inches, or 4.6 cm, and its wings are quite lovely. The front wings are mostly white with brown along the edges and a few brown and yellow spots, while the rear wings are a soft yellow-brown with a narrow brown edge. It has furry legs that are white with black tips. But when the moth folds its wings to rest, suddenly those pretty markings make it look exactly like a bird dropping. It even stretches out its front legs so they resemble a little splatter on the edge of the poop. But it’s not just insects that mimic other things. We’ve talked about frogfish before in episode 165. It has frills and protuberances that make it look like plants, rocks, or coral, depending on the species. The leafy seadragon, which is related to seahorses and pipefish, has protrusions all over its body that look just like seaweed leaves. It lives off the coast of southern and western Australia and grows over nine inches long, or 24 cm, and it moves quite slowly so that it looks like a piece of drifting seaweed. No

Please enter. It will be embarrassing if no one does. Anyway, Lorenzo wants to hear about the northern gannet, a sea bird that sort of looks like a gull who mastered the blade and is probably an assassin. Its bill is large, silvery-blue, and dagger-like, outlined with black at the base that makes a dramatic mask. This mask is actually bare of feathers, showing the bird’s black skin. Otherwise it’s mostly white, with a wash of pale golden on the head and neck, black-tipped wings, and gray legs with webbed toes. But it’s also really big, almost the size of a pelican. Its wingspan can be over six feet, or 184 cm. It can weigh almost 8 lbs, or 3.6 kg, too. Like many sea birds, the northern gannet breeds in colonies that can number in the thousands, and it only breeds on oceanside cliffs, mostly on islands off the coast of eastern Canada, Iceland, and western Europe. It’s especially common around the British Isles. So many birds may be nesting at once that the cliffs appear white from a distance, like snow fell on the clifftops, but instead of snowflakes, it’s gannets! While the northern gannet will sit on the water after diving, the only time it actually sets foot on land is when it breeds. It doesn’t walk very well, which is why it nests on cliffs. It’s easier for it to get airborne from a cliff. It can only take off from the water by facing into the wind and flapping hard, but if it’s not windy enough it can’t get airborne and it just has to float there until the wind picks up, probably feeling pretty foolish. But it swims well so if it is stuck on the water, it can swim along with its head under water, looking for fish it can grab. But most of the time the northern gannet is in the air, and it is built for speed and efficiency. Its long, narrow wings allow it to reach high speeds, up to 40 mph, or 65 km/h. It’s not very maneuverable, though, except for one specific move. The northern gannet is a diver. It’s a diver extraordinaire! It can reach incredible speeds while diving, up to 62 mph, or 100 km/h. When it dives, it holds its body rigid and angles its wings back, then folds the wings tight against its body just before it hits the water. It can dive up to 36 feet deep, or 11 m, and then it will swim farther down, sometimes over 80 feet deep, or 25 m. Its eyes are sharp and adapted to seeing both underwater and above water, so that as soon as it plunges into the water it can look around for fish. It uses both its feet and its wings to maneuver underwater. The northern gannet mostly eats fish, but it will also eat squid if it happens to come across one. It prefers small fish like sardines and anchovies, but any fish that swims in a shoal is its favorite. Groups of northern gannets will dive together into a shoal of fish, and swallow the fish underwater. The northern gannet especially likes to follow whales and fishing boats to grab fish trying to escape, injured fish, or fish that are discarded as too small or the wrong kind. Northern gannets live a long time, with the oldest known bird living past 34 years old. It’s not considered an adult until it’s about five years old. Breeding season starts in spring. The male finds a nesting site, or reclaims the nesting site he used the previous year, and defends it from other males, while females fly over the island and look for a male with a nesting site they like. Pairs generally mate for life, so many females are looking for

Episode 189: The Handfish and the Lumpsucker

This week we have two more listener suggestions, so thanks to Rosy and Simon! They both suggested small but intensely interesting fish! Further reading: The Handfish Conservation Project – Name a Fish! Further watching: Pacific Spiny Lumpsucker making adorable faces The only smooth handfish specimen in the whole world: In case you were wondering why it’s called a handfish (this one is a spotted handfish): A red handfish. You’d be angry too if there were fewer than 100 individuals left in your species (photo by Rick Stuart-Smith): A Pacific spiny lumpsucker: HOW IS THIS REAL? I AM GOING TO DIE. These are real lumpsuckers on a real balloon in an aquarium. Apparently it’s a birthday party thing to do in Japan: The sucker part of the lumpsucker: SO ANGY: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This week we’re going to learn about two interesting fish, but first a CORRECTION! In the hyena episode last week I called the hyena a canid, and it’s not! Yikes, that was a major blunder on my part. Thanks to Bal for the correction. Hyenas aren’t even very closely related to canids at all. They’re in the family Hyaenidae while canids are in the family Canidae, although both are in the order Carnivora along with cats and walruses and raccoons and weasels, etc. AND thanks to Simon who also let me know that the striped hyena lives in the Middle East and Asia as well as Africa. Sorry, y’all. I hate when I make mistakes. Anyway, back to the fish! We’ll start with the handfish, which happens to be a suggestion by Simon. Simon sent me an article about the smooth handfish specifically, and it’s a sad article because the smooth handfish has been declared extinct. The smooth handfish used to be a common fish that lived off the coast of Tasmania in warm, shallow water. It was reddish-brown with darker brown markings, and it grew to about 1 3/4 inches long, or 4.4 cm. But the area where it lived was dredged so intensively for oysters and scallops up until 1967 that the fish’s habitat was destroyed. It was described in 1802 from a single specimen caught by a French naturalist, but that’s the only smooth handfish anyone ever bothered to collect for science. And now it’s the only specimen we have to study. The reason the smooth handfish was so vulnerable to habitat loss is that it didn’t have a larval stage where newly hatched fish could disperse to new areas by floating on currents. Handfish eggs hatch into teeny baby handfish, not larval handfish. As a result, it was restricted to only specific areas and when those areas were destroyed by dredging, the fish was driven extinct. And the really awful thing is, the only reason people stopped dredging for oysters and scallops is because they’d been so overfished that there basically weren’t any left. The smooth handfish is actually the first marine fish known that has gone extinct in modern times. There are 13 other species of handfish known in the world, but they’re all endangered due to pollution, habitat loss, and the spread of invasive species. Like the smooth handfish, other handfish species lay eggs that hatch into juvenile fish instead of larval fish, so they’re also especially vulnerable to habitat loss. For example, there are fewer than 100 red handfish alive in two small areas off the coast of Tasmania. We know because each fish has unique markings, which allows conservationists to identify individuals. A group called the Handfish Conservation Project has put together a database of living individuals, and if you donate at least $1,000 (in Australian dollars) you get to give one of the fish a name. I’ll put a link in the show notes so you can go look at the fish and see the names some of them have been given. The names include Ginger Ninja, Knuckles, Rosie Palm, and The Stalker. The handfish is called that because its pectoral fins look like big flat hands that it uses to walk along the ocean floor. It’s actually related to the anglerfish, and like anglerfish it has an illicium above its mouth. Anglerfish use the illicium as a lure to attract animals that it then gulps down, but the handfish’s illicium is relatively small and researchers aren’t sure if all species use it as a lure. We’re not even completely sure what handfish eat, although there are reports of handfish eating polychaete worms, small fish, and crustaceans like amphipods and shrimp. All the species live off the coast of Australia, especially around Tasmania. The largest species only grows to about 6 inches long, or 15 cm. That is pretty much all we know about the handfish, so let’s move on to our other fish today, a suggestion by Rosy. Rosy wants us to talk about the lumpsucker, and I cannot argue with this because they are weirdly adorable fish. The lumpsucker lives in cold waters near the Arctic. Most species live in the North Pacific but some also live in the North Atlantic. It doesn’t swim very well and, like the handfish, it spends most of its time

BONUS! All about animal poop

BONUS TIME! A dung beetle rolling some poop: Butterflies on poop: Wombat poop is cubes! Show transcript: Welcome to a bonus episode made out of a bonus episode. Since this week’s topic is one that some adults may decide they don’t want their young kids listening to, because it goes into detail about hyena reproduction, I decided to unlock a Patreon bonus episode for everyone to listen to. But then I decided to actually release that episode so that listeners can download it normally in the main feed. Those of you who want time to pre-screen the hyena episode to see if it’s appropriate for your kids to listen to can listen to this episode together in the meantime, and those of you who decide the hyena episode isn’t right for your kiddos still have an episode this week as usual. The rest of you get two episodes this week! A special thanks to our Patreon subscribers who support the show and get twice-monthly bonus episodes like this one every single month. This is the only part of the episode that is new; the rest was originally recorded in late 2018. And here it is! The topic for today’s episode was suggested by my aunt Janice. Janice doesn’t actually listen to the podcast, not even the main feed podcast, but she sends me topic suggestions every so often. Recently, she texted me out of the blue, saying, “I’ve decided that you need to do a podcast devoted to the topic of animal poop. Butterflies eat it, dung beetles roll it, owls leave pellets with tiny animal bones, guano has commercial uses, people make no-bake chocolate and peanut butter cookies and call them cow pie cookies. Goats are gumball machines! Why are so many animals’ poops little Raisinets, but others are long thick Tootsie rolls? Why do so many animals eat poop?” Only, she didn’t say poop. She said another word. Then I texted her back, telling her how wombat poop is actually little cubes, which blew her mind. If you listened to the spookiest owl episode recently in the main feed, you may remember about owl pellets. Those do indeed contain bones and other indigestible parts of the owl’s prey, like fur or feathers, but the pellets themselves aren’t the same thing as poops. Poop, or more properly excrement or feces, is what’s left after food passes through an animal’s digestive system. It contains not just the remains of food that wasn’t fully digested, but secretions from the digestive system, bacteria that live in the digestive system, and of course water. The secretions include a chemical called stercobilin, which helps the body digest fat, and which is what makes your poop brown. Yes, I googled what poop is made up of. I googled it so you wouldn’t have to. I didn’t want to know this stuff. You’re welcome. Incidentally, the bacteria in your digestive system actually help your digestion and do other good things for your body. People who have to take strong antibiotics or radiation treatment sometimes have trouble with their digestion because the antibiotics or radiation can accidentally kill a lot of the beneficial bacteria in the digestive system. Getting the bacteria back in such cases is simple, usually taking a doctor-prescribed supplement of probiotics, or in less acute cases, just eating a lot of yogurt or certain other foods, like sauerkraut or kimchi, which naturally contain probiotics. Humans aren’t the only animals with beneficial bacteria in the digestive system. In fact, all animals have them. Some young animals, including horses, will eat their mother’s poop to gain digestive bacteria. Personally, I prefer yogurt. Oh, and you know how dogs like to get into the cat’s litter tray and eat the cat poop? That’s because cats are obligate carnivores, which means they have to eat meat for almost all of their nutritional needs. That means cat poop is relatively high in protein, which makes it attractive to dogs. I can’t believe I’m talking about this. I hope you’re not snacking while you listen. I’m sure a lot of us have seen butterflies gathered together on a hiking trail or in a pasture, their wings fluttering in the sunlight, and when you get too close they all fly up together and swirl around, making you smile and think about how wonderful it is that you live in a world with butterflies. Then you look at what the butterflies were gathered on, and it’s an animal poop. Why do they do that? While butterflies do eat nectar, nectar doesn’t contain all the nutrients they need. It especially doesn’t contain much sodium—you know, salt. So butterflies get sodium and other nutrients from rotting fruit, rotting meat, and animal dung. Also, if a butterfly has ever landed on you, it was probably attracted to your sweat, which contains salt. A lot of times, male butterflies will collect nutrients from poop and other sources and offer them to the female as a gift, hoping she’ll choose him as her mate. I personally would rather have chocolate, but I’m not a butterfly. Moths also eat poop and other unsavory things, but some moths will cut out the middle-ma
