Orcas eating just the sharks liver is interesting, they have been known to eat only the tongue of whales, leaving the rest of the carcass. I'm guessing for similar reasons, tongue being tasty and highly nutritious to them.
This known behavior was used by whalers who had a pact with a group of orca in Eden, South Wales.
In exchange for helping the whalers hunt baleen whales, the whalers would leave the tongue of the whale to the orcas.
