Whales, dolphins and porpoises are all mammals (there is an unrelated fish also called the Dolphin or Dolphinfish). These mammals evolved from extinct hoofed carnivores and gradually adapted to an exclusively marine life. Their similarity in form to fish is an example of convergent evolution; anatomical similarity to land mammals confirms their true origins.
