What can eat a killer whale?
Killer Whales are at the very VERY VERY TOP of the food chain in the ocean. Even the Great White shark and Blue Whales would stay clear of this animal. Until we discover something greater in the ocean, it is fair to say that nothing WILL eat a Killer Whale. Killer Whales have not been known to kill each other, and humans have not been recorded directly eating the flesh of killer whales (they are usually hunted for their blubber, which is used in making oil, not eating). But regardless of that, Humans and Killer Whales COULD eat killer whales. You could go further and say sharks could eat baby killer whales (although its unlikely because youngsters are carefully guarded by their parents), or even other giant animal like Polar Bears and Leopard Seals… Any carnivore CAN EAT a killer whale, its just a matter of killing it fist!
