Similar story with Orcas. There's 1 pod of orcas which figured out how to hunt Great Whites, and they teach it to the young. They grab a fin of a shark that's small enough to bully (maybe a measly 11 feet, lol), and hold it upside-down until it dies. (Sharks have a thing where they are paralyzed when they are upside-down I guess) Then they rip it apart and eat its huge, fatty liver.
