On my visit to the Everglades, I was surprised to learn that the U.S. does have crocodiles. In the Everglades, they live in the salt water. Alligators, on the other hand, live in the fresh water. Yyou can find both of them in one location in the Everglades but, we didn’t visit there.
Everglades III: American Crocociles and Alligators
However, I was able to get close and photo one crocodile and several alligators. Not only are their snouts different, but crocodiles have more teeth that stick outside of their mouths when their mouths are closed.
