The scientist was startled as he watched the injured beast ravaged in a cannibalistic attack while releasing an oceanic black tip shark into the sea.

Despite being half-eaten by other sharks when scientists released it into the sea, a ‘zombie shark’ has been observed actively seeking for prey.

Dr. Mario Lebrato, 35, released the oceanic black tip shark into the sea off the coast of Spain before it was attacked by a group of other sharks, inflicting fatal injuries on the unwary animal.

The zombie shark continued to swim despite being ‘half eaten’

These included many bull sharks, which may weigh up to 400kg, according to the biologist.

Despite the onslaught with a huge chunk of its body missing after being bitten off, the shark fought for its life and attempted to swim away.

 

The shark struggled for around 20 minutes before eventually succumbing to its injuries

Dr. Lebtrato stated that the shark fought for almost 20 minutes before succumbing to its injuries.

He said: “Sharks eat sharks, that is well known, but it is super difficult to film and document.”

Fellow sharks set upon the black tip, inflicting fatal injuries

In the video, the marine predator is well hidden beneath the surface of the water when it sees a bunch of seals.

The seals attempt to keep together but eventually separate, and the shark seizes the opportunity to attack.

The apex predator rushes up from below with its jaws wide open, showing hundreds of razor-sharp fangs in a terrifying turn of speed.

It knocks the seal skywards while crunching down with its powerful bite.

The shark then flies through the air with the seal in its teeth, turning horizontally mid-leap before crashing down into the ocean with a big splash.
