In what could pass as an outtake from "Jaws" -- a guy was bitten by a shark and dragged off his boat during a fishing trip in Florida last week ... and the video is wild.
The clip shows a group of fishermen in the Florida Everglades, anchored in a marsh. You see one guy's rod in the water, and another guy (who's on camera) bends down and starts to lean over the side of the small boat they're all in.
As the dude starts to consider putting his hand in the water, one of his buddies tells him it's probably not a good idea.
