Some consider the great white shark to be the fiercest predator in the ocean. Now Free Willy is giving the species a run for its money. Orca whales' diet traditionally includes fish, squid, birds, seals, and other whales. Now some are adding Jaws to the menu.
Several populations of orca whales have learned how to attack sharks, including the great white, with various techniques, including what some scientists are calling the “karate chop.” To execute this sly move, the orca drives the shark to the surface, then comes down on top of the shark and turns it upside down, at which point it enters a paralyzed state. In fact, all the attack methods ultimately end with the shark on its back.
