Orca Shark bites

Predator becomes prey as killer whales hunt great white sharks in South Africa. It’s not cannibalism of course, so maybe I should not have used the Hannibal Lector quote from Silence of the Lambs, but they mentioned eating the liver, so it came to mind. Sharks do have big oily livers, which supposedly help them with buoyancy instead of an air bladder in bony fishes, at least from what I recall from dissecting a dogfish in university.
