Of all the ocean's dangerous creatures, none strike more fear into the human heart than the great white shark. The largest predatory fish on the planet inspired Steven Spielberg's movie Jaws, which sealed the shark's image as a man-eater.

But experts insist that while the great white's hunting habits do earn it the title of a seal serial killer, attacks on humans are rare. As marine biologist Francesco Ferretti says: "Spielberg has a lot to answer for. In reality you have about as much chance of being eaten by a shark as you have of winning the lottery twice."
