Great white sharkars the largest predatory fish on our planet. They are grey with a white underbelly, from where they get their name. They have a streamlined shape and powerful tails that propel them through the water at over 60km per hour. Any creature unlucky enough to find itself in the gob of a great white is in for a nasty shock! Because this marine beast's mouth is equipped with a set of 300 sharp, triangular teeth arranged in up to seven rows. Whilst many think of these beasts as fearsome man-eaters, humans aren't, in fact, on the great white's menu.
