A video has captured the moment a nearly five-metre tiger shark devoured a floating cow in the middle of the Indian Ocean.
The footage was filmed by onlookers who were sailing off the French Island of Mayotte when they noticed thrashing in the water.
As they got closer, they found that the commotion was caused by the shark ripping into a 200 kilogram horned zebu cow.
The video shows the shark biting into the carcass of the cow, which appears to be dead.
It is believed the footage was taken earlier this month and was filmed about 500 metres away from the beach with an underwater camera.
The cow is understood to have fallen off a makeshift boat and into the sea.
