Study finds nutritional stress driving decline of Hawaii's endangered false killer whales

Summary

A recent study published in Endangered Species Research reveals that Hawaii's false killer whale population, already critically endangered with fewer than 140 individuals, is suffering from nutritional stress. Researchers used drone photos from 2019-2025 to model body size and weight of 64 whales, finding evidence that the whales are not getting enough food. This nutritional stress is further depressing an already threatened population that has been declining for over a decade.
