How do you tell the difference between crocodiles and alligators?

Crocodiles and alligators look so alike that it is often very difficult to tell them apart when you see them in zoos. They both have tough, scaly skins, and when they are lying in water, their nostrils, eyes and ears are on the same level.

The answer is to wait until they appear on dry land, and then take a good look at their teeth ! If you look carefully, you will find that crocodile teeth are more or less in line with each other, except for the fourth tooth on each side of the bottom jaw which is larger than the rest. When the crocodile closes its mouth, these two teeth fit into a notch on each side of the upper jaw so that you can see them. Alligators, on the other hand, have all their top teeth outside their bottom teeth, so that when they close their mouths, no teeth can be seen.
