How is an alligator different from a crocodile?


A crocodile has a ‘V’ shaped snout, whereas an alligator has a ‘U’ shaped snout. When a crocodile closes its mouth, the fourth tooth in the lower jaw sticks up outside the top jaw. However, there is a well-defined constriction in the upper jaw behind the nostrils to accommodate it. When an alligator does the same thing, the tooth is hidden. This is because, in the alligator, the upper jaw is longer than the lower jaw.
