Fish-eating killer whales prey on around 30 species of fish. For some dolphins species, Killer whales is the most deadly predator, and it is also a dolphin! Orcas feed on a wide variety of fish, mollusks, and crustaceans, but if they find a dolphin, they do not hesitate to grab it and feed on it. They usually catch the smallest individuals, the small species or the young dolphins
