The American Alligator is a big reptile that is actually not as aggressive as the Crocodile, although they can still be dangerous. Alligator teeth don’t show, but the Crocodile’s teeth show. The head of a Crocodile is longer and narrower while an Alligator’s head is larger and rounded. Alligator feet are not webbed like Crocodile feet. Alligators can weigh up to 1,000 lbs and can grow up to 10-19 ft. Adult male gators are usually bigger than female gators. A Crocodile can grow up to 19 feet and 2 inches. The Crocodile can weigh up to 1,100 lbs. The habitat of the American Alligator is swamp lands in the U.S. or southern Florida. Crocodiles normally live near rivers and lakes and can live in southern Florida, tropical places in Africa, Asia, and Australia. I like the Crocodile the best because they just look cool. Which one do you like? The Crocodile or the Alligator?
