Killer Whales Chase Speedboat
They don't call them killer whales for nothing!
Watch this scary clip as a pod of Orca's chase a speedboat off the coast of San Diego.
The giant creatures get dangerously close to the boat as they crash through the waves, and the footage filmed above and below the water show how quick these creatures can move in the water.
Fortunately they didn't end up under the craft and tipping it over!
