I've been told that beavers are not very friendly, and that if I ever saw one, I should stay clear. That is some advice that this guy should have taken as he gets attacked after he stopped to take a beaver's picture that he found on the road.

The further information following the video on this post says that the man was bitten in his thigh.  It's an area that a main artery runs through.  Unfortunately, the man did not survive the attack.
