The killer whale is a toothed whale belonging to the oceanic dolphin family. Killer whales have sophisticated social structures, hunting techniques and vocal behaviours, which are passed across generations. They also have keen hearing and good eyesight, both in and out of water, and a developed sense of touch. The killer whale's large size and strength make it one of the fastest of marine mammals. The average lifespan of males and female varies according to habitat and lifestyle. The female killer whale is thought to live the longest, to a maximum age of 80 to 90 years.
