Show Notes
New research reveals that northern resident killer whale mothers struggle to regain body fat after pregnancy and nursing, especially with multiple living offspring. Despite ample food, these moms face a tougher challenge if several calves remain for lifelong care. The study, published in Scientific Reports, found that living offspring, not total births, significantly slows fat recovery. This highlights the immense maternal investment amid human threats, emphasizing the need for better protection for these threatened orcas.
