Off the coast of Costa Rica, we witness for the first time a tiger shark being hunted down by a group of orcas (aka killer whales).

The orca is one of the smartest and most mysterious of all oceanic creatures; and the tiger shark one of the most feared. The killer whales prove true to their name — though formidable, this fish stands no chance.

This particular attack took place at Chatham Bay on Cocos Island, Costa Rica, on September 8.

This behavior had never been documented before this event. The remarkable footage was captured off the coast of Costa Rica by underwater photographer Caroline Power and British marine biologist Nicholas Bach.

The shocking video shows three killer whales working as a team to force the panicked shark to the surface, tiring it out and taking opportunistic bites at its fins.

Eventually, a large bull moves in to deliver the final blow while flipping the shark onto its back in the process — this induces a state of paralysis known as tonic immobility. The pod then takes turns at eating the seven-foot shark down before disappearing back into the ocean.

Nature can be brutal.
