Alligators have a much more rounded snout than crocodiles.
There are only two living species of alligator in the world,
the wellknown American Alligator and the less-known Chinese,
The Chinese Alligator is smaller than its American cousin,
typically reaching some 5 feet in length, and has armour on
its underside as well as its topside. It lives along the
southern Yangtze River and is critically endangered.
