Heart-stopping moment great white shark crashes into kayaker and almost capsizes him while it was hunting prey off New Zealand

 Greg Potter had been sitting back in his pedal kayak admiring nature from a distance as he watched a young great white shark shooting through the ocean surface to try and catch a seal off New Zealand's Eastern Cape. But as the young shark sought to land the prey in its jaws, the spectacle got a little too close for comfort, almost plunging the kayaker himself into the action. The shark twice fired into the bottom of Greg's kayak, nearly knocking over the vessel on the second time of trying.
