This 20 day old video just went viral, accumulating over 600,000 views this week after being featured on GrindTV.

Nature shows are chock-full of underwater footage, and there is always a special focus on sharks. All that shark footage has to come from somewhere, and to get a good shot divers must literally dive into the shark’s lair and press record.

But this scuba-cameraman got a little to close for comfort with a very nice sized Tiger Shark who almost bit off his leg. Now you can appreciate the next Shark Week that much more.
