Watch: Killer Whales Take Down Tiger Shark
This incredible footage was captured off the coast of Costa Rica by underwater photographer Caroline Power and British marine biologist Nicholas Bach.
They had a close up encounter with the whales during their dive, and whilst on the way back to shore they spotted them again. This time they were on the hunt for the tiger shark, all three of them working as a team to trap the shark against the surface.
Eventually the orcas succeed in flipping the shark onto its back, which induces a state of paralysis known as tonic immobility.
