Conservation efforts have saved the American alligator from the brink of extinction, and its no longer an endangered species. The American alligator is in good hands now, but we have to make an effort to protect it. Its survival is directly linked to the survival of the other creatures in the ecosystem. NYC It is easy to confuse an alligator and a crocodile at first glance. They are really quite different though.
Alligators have broader heads and blunter snouts.
Their lower teeth fit inside the edge of the upper jaw and cannot be seen when the mouth is closed. Crocodiles, on the other hand, have a narrow head and longer snout. Their lower teeth can be seen when their mouths are pone. Another difference between these animals is that crocodiles prefer brackish or salt water, while alligators are usually found in fresh water.
