Great White Sharks are generally elusive animals and fights between them are rarely documented.
Watch this rare footage of two great white sharks attacking each other in south Australia.
The video, shot by London-born diver Adam Malski, shows a 4.8-metre shark attacking a smaller rival in waters off the Neptune Islands.
The larger shark, known locally as Gilbert, survived the attack while the other animal, which was about 2.5 metres in length, has reportedly not been seen since.
