How do you tell the difference between an alligator and a crocodile? Look at their snout. Is it shaped like a V or a U? Crocodiles have a V shaped snout while Alligators have a U shaped snout. Now look at their teeth. Crocodiles teeth are longer and when their mouths are shut, their teeth stick out. Can you tell the difference in the coloring pages below?
