Whats the difference between the crocodiles and the alligators? i always wondered..?

and crocs are paler green and like brackish or salty water so are nearer the coasts, where gators are darker with more rounded snouts and like fresh water lowlands." I'd bayou a swamp, but it's a marsh-in-wetland (know of fens)." my pet alligator used to say to charm the birds.
