The Delphinidae vary in size from 1.2 metres and 40 kg (Heaviside's Dolphin), up to 7 meters and 4.5 tonnes (the Orca). Most species weigh between about 50 and about 200 kg. They are found worldwide, mostly in the shallower seas of the continental shelves, and all are carnivores, mostly taking fish and squid.
