Humpback whales are recovering to 80,000, thanks to diet shifts, adaptability, and efficient feeding.
Humpback whale populations are rebounding to about 80,000, up from a low of 10,000, with researchers attributing their recovery to dietary flexibility, including switching from polar cod to krill in response to changing food availability.
Studies using stable isotope analysis of whale skin show lower nitrogen-15 levels linked to krill consumption, indicating a shift likely driven by environmental changes like Arctic ice loss.
Their energy-efficient feeding strategies, such as "trap feeding," and adaptability to new habitats are helping them thrive despite climate change, making them a rare conservation success story.
