VIDEO: Surfer fights off shark with fists

Fanning, three-times world surfing champion, was paddling out to ride his first wave when the unidentified species of shark surfaced next to him, knocking the 34-year-old off his board.
The Australian managed to fight off the predator, hitting it on its back before it swam off, leaving him shaken as he waited for a support boat to return him safely to shore.
