Crocodile and a shark face off in Australia’s Top End

Terrifying footage has captured a curious shark stalking a crocodile in crystal clear waters in Australia's Top End. The croc was seen floating on the water's surface in the Northern Territory's Wessel Islands last Saturday as a shark lurking beneath it, circling the reptile.

In the nerve-wracking footage of the two apex predators, the brave shark, believed to be a tiger shark, is seen swimming right behind the large croc which then appears to flee onto nearby rocks. (Daily Mail)
