Killer whale or orca – the whale having teeth belonging to ocean family of dolphins which it is the largest member. Killer whales have a various diet though the separate population often specializes in particular production types. Some feed only on fish while others hunt marine mammals, such as seals and other species of a dolphin. They as it was known, attacked cubs of a whale of baleen and even adult whales. Killer whales – peak predators as no animal hunts them. Cosmopolitan variety, they can be found in each of world oceans in a set of marine environments, from the Arctic and Antarctic to the tropical seas which are absent only in the Baltic and Black seas and some areas of the Arctic Ocean
Killer whales very social; some population consists of matrilineal of family groups (podcasts) which are the most stable of any kind of animals. Their difficult hunting methods and vocal behavior which are often characteristic of specific group and passed on generations, were described as manifestations of culture of animals.
The International Union for Conservation of Nature notes the conservation status of the orca as little data due to two or more species of killer whales being different species. Individual local populations are considered threatened or threatened due to lack of food, pollution, conflicts with human fishing. In late 2005, southern killer inhabitants, were listed as endangered species.
Wild killers are not considered a threat to humans, but there have been cases of captives killing or injuring their handlers in marine theme parks. The killers are highly distinguished by the mythology of indigenous cultures, their reputation ranging from the soul of man to ruthless killers.
