Caption: The picture shows the head of an alligator and a crocodile. Can you tell which is which?
Crocodiles and alligators are reptiles. They look like giant lizards. They have long bodies. They have short legs. They have long tails. They both spend a lot of time near the water. You might see them floating in the water. When they are still, they can look like floating logs. Their long tails help them to swim in the water. They are fast swimmers!
