The moment a whale delivers a deadly 'karate chop' blow to a killer shark

These incredible pictures demonstrate how orca whales use a 'karate chop' to stun and then finish off killer sharks.

In a rare battle of beasts these images show how several populations of skilled killer whales around the world have learned how to overcome huge sharks, that most animals give a wide berth.

Using a combination of superior brain power and brute force, the highly-intelligent orcas are able to catch and eat what many think of as the ocean's top predators.

Moments before the deadly blow. The raised fin is about to come crashing down like a karate chop on a shark (circled). It has been driven to the surface by the orca before this coup de grace

No escape. A killer whale with a Mako shark in its grasp. After stunning the shark, the orca grasps the dazed creature and flips it upside down. When sharks are quickly flipped upside down, they enter a paralysed state known as 'tonic immobility' - making for an easy meal
