Abalone + White Shark = Cool Video

"This 4 metre plus female great white had just bitten Mark's cage and was circling when he turned on his camera .... at 1.09 he see's it approaching from behind his cage. He's been down at 26 metres for over half an hour and is forced to make a decision. Stay on the bottom and run into decompression time or confront it .... Starvation Bay, South Coast Western Australia, October 2011."
