crocodiles vs. alligators

Some people think that alligator or crocodile is a same animal but they think wrong. The truth is they are quite different.Alligators have a very broad, wide snout, and crocodiles have a narrower snout and jaw. Also crocodiles often have a lower tooth that juts out noticeably,while an alligator's fourth tooth is hidden. They have been considered villainous, man-eating monsters for centuries. Are they really so dangerous? The answer is yes. Alligators are actually "not" known for being aggressive toward man unless nesting or unexpectedly disturbed, but crocodiles do and have killed humans.The Nile crocodiles are known for the large number of human fatalities they cause every year. The best thing is never to approach one, even for a good “shot” with a camera.
