An alligator is a species of crocodilian reptile that lives in North America, South America, Europe, Asia, Africa, and Australia. It has a long snout and a broad, rounded head with small eyes. The alligator's skin is thick and scaly. It has a long body and a tail that is usually longer than its body. Its color can vary from light brown to dark gray or black. A crocodile is a species of crocodilian reptile that lives in Africa, Asia, and Australia. It has a long, narrow head with large eyes and a long, slender body. The crocodile's skin is smooth and shiny. It has a long, pointed snout and a forked tail.
