Two daredevils risked serious injury by wading within feet of an injured 4.6m great white shark.
Dale Pearson paddled into the sea by his home in the Sea of Cortez, Mexico, to inspect the animal, which had been injured by a rotor blade of a boat.
In the end though it wasn't the huge predator Dale and his friend had to worry about - but a stingray which stung one of them on the foot.
The video begins with Dale walking out to sea and approaching the shark, which was thrashing around, spreading its blood through the water.
