This video is disturbing and definitely not for the faint of heart.

I contemplated putting this video up. It's disturbing to say the least. Everything from what's happening, to the guy's reaction, is kind of haunting.

The video starts with his arm in the water. As he pulls it out, there is a hammerhead shark devouring his arm up to his elbow.

He then begins flailing and screaming as the shark stays attached to him.
