And the Spanish researcher Mario Liberato published a very rare video of sharks devouring each other, at a depth of one to two meters below the surface of the Indian Ocean, off the coast of Mozambique.
According to the Daily Mail, Liberato was filming the oceanic black-headed shark when it was released back into the ocean, where it was devoured by a group of about 10 sharks.
The footage shows the shark after being fatally attacked, with huge pieces ripped from its side, as blood and flesh flow in the water.
A huge hole can be seen in the side of the shark, with a second, smaller piece of meat missing towards the tail fin.
The shredded flesh appears in the murky water caused by the blood seeping from the huge fish, as it struggled in vain away from the others.
Despite his injuries, the shark continued to swim while other sharks continued to circle around it in an ominous manner.
Liberato said that after a five-minute struggle following the attack, the shark died of its wounds.
He added, “I have been working in Mozambique for 4 years now, and the phenomenon of sharks devouring each other is very well known, but it is very difficult to photograph and document it.”
Professor Mark McCann of the Australian Institute of Marine Sciences believes that all shark species have tendencies to eat some meat, including the great white.
