Despite decades of research, the diets of killer whales remain mysterious, especially in remote parts of the North Atlantic Ocean. But scientists can now infer the precise feeding habits of these apex predators by looking at the lipid (fatty acids) composition of the whales' blubber. All they need is a small skin biopsy (collected from small boats with special darts). Our research team collected biopsies from 200 individuals across the North Atlantic Ocean to reveal large variations in the whales' diets. Photo: Anaïs Remili / The Icelandic Orca Project.
