Killer whales as well as other toothed whales dolphins have outstanding intellectual abilities; some scientists believe they have the beginnings of mind. For example, in a district of the southern coast of Australia a pack of killer whales regularly for many years helped local whalers. They drove the flock of baleen whales in shallow water, where they waited for people with harpoons. The end of such cooperation was always the same - people are meat, and baleen, whales - the rest.
