Question

rows of teeth. the crocodile in particular is known for having a very sharp fourth tooth in its lower jaw that juts out even when its mouth is closed, and caimans are known for their sharp, dagger - like teeth. which term matches the picture? alligator crocodile caiman

Explanation:

The text mentions that the crocodile has a very sharp fourth tooth in its lower jaw that juts out even when its mouth is closed. The picture shows an animal with a tooth jutting out when the mouth is closed, which matches the description of a crocodile. Alligators have broader snouts and their teeth are not as prominently visible when the mouth is closed as described for crocodiles. Caimans are known for dagger - like teeth but the key identifying feature here is the jutting fourth tooth which is characteristic of crocodiles.

Answer:

crocodile
