Adult male elephant seals are generally larger than sharks, so the seal is first immobilized, by the shark attacking the rear end of the seal first, and then waiting for the seal to bleed to death, before tearing chunks of flesh from it. Juvenile elephant seals are more commonly eaten though. To avoid being detected by their echolocation, dolphins, and porpoises are attacked from below, behind or above. Prey such as harbour seals is taken to the bottom of the ocean. Once the seal stops struggling, it is eaten. Sea lions are struck mid-body from below, dragged and then consumed.
Great White Sharks have also been observed attacking and killing smaller species of whales, such as the Stejneger’s Beaked Whale and Cuvier’s Beaked Whale. When the shark prey’s upon a sea turtle, the turtle is rendered immobile, by the shark biting through the carapace around one of the turtle’s flippers, making for easy feeding.
