A long, narrow muzzle make it easy to distinguish a Crocodile from the North American Alligator. Definitely not someone I'd want to go swimming with... Although most dangerous in water, they can also move surprisingly fast on land.
Luckily, this guy is resting. Crocodiles seem to sleep with their eyes open. At least I think he's asleep. He didn't move or blink at all during the entire 20 minutes I watched him. Very eerie.
