The orca, also known as killer whale is a toothed whale. A characterized by the odontocete teeth, so the whale is a whale tooth. Although it is known as killer whales, it almost never attack humans. The orca eat penguins, fish, sea lions, porpoises, etc.. There are three distinct types of killer whales, orcas nomads who travel alone or in small groups, they are constantly moving; resident orcas, which always return to the same location during a certain period and move in groups five to 50 individuals and offshore killer whales, which move in groups of 30 to 60. Offshore killer whales are a derivative of resident killer whales.
