The recent autopsy of a partially devoured great white shark confirms a brutal hunting trend—killer whales around the world are not afraid to attack the fearsome fish, especially when they get a taste for liver.

Great white sharks are washing up dead on beaches with enlarged brains in what is becoming a spiralling marine mystery.
