Want to know the difference between an alligator and a crocodile?
Their teeth are a good way to tell them apart.
Almost all of the crocodile's teeth stay on the outside of the mouth when closed.
The upper and lower teeth showing makes them look like they are smiling.
Gharial teeth look like a zipper; they are all about the same size.
With teeth like these, who needs to chew?
The alligator has a slight overbite--the bottom teeth fit inside the top.
Baby crocodiles are born with an "egg tooth" that falls off soon after
hatching. Crocodilians are built to grab and tear their food. All crocs
have at least 60 teeth which help them catch their prey.
They may have as many as 3,000 teeth in the course of a lifetime.
