COSTA RICA (PIX11) — The moment three killer whales took down a tiger shark was captured in what is believed to be the first video of its kind.

Underwater photographer Caroline Power and British marine biologist Nicholas Bach captured the footage Sept. 8 off the coast of Costa Rica  in Chatham Bay on Cocos Island. The video shows three killer whales working as a team to kill the tiger shark.

The whales swim around and below the shark forcing it to move to the surface. Wearing it down, the whales bite at its fins. Eventually, the shark sustains a “death blow” and flips onto its back, causing it to go into a state of paralysis known as tonic immobility.

After the attack, the whales take turns eating and stripping the 7-foot shark down to its bones before disappearing back into the ocean.

The video, posted by Barcroft TV, was published Sept. 26 and has since been viewd more than 870,000 times.
