Scientists develop a model to reveal wild killer whales’ diets

A new study presented a method to reconstruct killer whales’ diets using the lipid composition of their blubber. By measuring these lipids, called fatty acids, in the killer whales’ fat and those in their potential prey, scientists can estimate the abundance of each prey species in the whales’ diet. This new method may hold the …
