Great White v Great White: Shark-on-shark attack caught on camera

A rare shark-on-shark attack has been caught on camera in the water off Australia's Neptune Islands.

Shark-watcher Adam Malski, originally from London, was filming what he thought was just one Great White swimming up to some bait near his boat.

But moments later, a second, much larger Great White appeared from the water and attempted to bite the smaller shark.

For a second their powerful jaws locked together in a battle between the ocean's most fearsome predators.

"I believe that it is extremely rare footage as Great Whites are elusive and still largely unknown creatures,” Adam said.
