The killer whale or orca (Orcinus orca), less commonly, blackfish or seawolf, is the largest species of the Dolphin family. It is found in all the world's oceans, from the frigid Arctic and Antarctic regions to warm, tropical seas. Killer whales are versatile and opportunistic marine apex predators. Some populations feed mostly on bony fish while others hunt sharks and marine mammals, including sea lions, seals, walruses and even large whales. There are up to five distinct killer whale types distinguished by geographical range, preferred prey items and physical appearance. Some of these may be separate races, subspecies or even species.[3] Killer whales are highly social; some populations are composed of matrilineal family groups, which are the most stable of any animal species.[4]
