They are also name killer whales because of their highly skilled hunting techniques and large diets. Orca belong to the Dolphin family, perhaps, but Dolphins then are classified as Toothed Whales along with several other species.
Another method they use involves hunting sharks where these dolphins attempt to attack the shark from underneath to bring it up to the surface of the water and will either try to ram it or use their flukes to try to flip the shark which temporarily paralyzes it so that they can consume the shark without fear of being attacked themselves.
