Large type B whales eat mainly seals, especially Weddell seals, and also hunt minke whales. Small type B killer whales have been observed hunting penguins and are believed to mainly eat fishes. Type C killer whales mostly eat Antarctic toothfish (Dissostichus mawsoni). Little is known about the diet of type D killer whales, however, they have been observed preying on Patagonian toothfish (Dissostichus eleginoides) caught on longlines. The feeding habits of resident and transient whales of the eastern North Pacific Ocean differ.
