The orca or killer whale (Orcinus orca) is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. It is recognizable by its black-and-white patterned body. A cosmopolitan species, orcas can be found in all of the world’s oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas; they are absent only from the Baltic and Black seas, and some areas of the Arctic Ocean.
Orcas are apex predators, as they have no natural predators. Orcas have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and other species of dolphin. They have been known to attack even adult whales occasionally.
They are highly social; some populations are composed of very stable matrilineal family groups (pods) which are the most stable of any animal species. Their sophisticated hunting techniques and vocal behaviours, which are often specific to a particular group and passed across generations, have been described as manifestations of animal culture.
