A swarm of killer whales has been seen carrying out a synchronous attack on the world's largest animal and may not have done so for feeding.

Unmanned aerial drone shots On May 18 in Mauritania, California, a group of deadly whales was observed carrying out a coordinated attack on a blue whale.

Urica whales, also known as killer whales, feed on predators of other marine mammals, including dolphins and seals. But even these terrifying predators do not stop at this point when the mature blue whale attacked the largest animal on the planet, which may be up to 100 feet long and weighs nearly 200 tons.

In this case, the big blue whale turned on its side and sent what looked like a wall of water and swam away much faster than the Urica whales, according to marine scientist Nancy Black, who filmed the event.
