Due to their low tolerance for salt, alligators typically live in fresh water habitats. Alligators will sometimes live in brackish water (salt water and fresh water mixed together) as well. Alligators primarily inhabit swamps and marshes, but can also be found in rivers, lakes, and other small bodies of water. They generally prefer warmer temperatures, but can survive in freezing temperatures as well. As opposed to alligators, crocodiles have modified salivary glands on their tongues to help them tolerate salt water. Crocodiles usually live near lakes, rivers, wetlands and some saltwater regions. They live in tropical climates because they are cold-blooded and can't generate their own heat. Crocodiles are found in the tropical areas of Africa, Asia, Australia, and the Americas. Alligators live in the southern United States and China. The United States is the only country that both alligators and crocodiles inhabit.  American alligators are most commonly found in Florida and Louisiana, and are less commonly found in Alabama, Georgia, South Carolina, Mississippi, and Texas. American crocodiles are usually found in Florida.
