1. Alligators vs. Crocodiles: crocodiles can be larger than alligators, although the American Crocodile and the American Alligator are more similar in size. Both average around 11 to 12 feet, though the crocodile still has a higher potential for extreme length. Because crocodiles grow longer, they also carry much more mass. A large male Saltwater Crocodile can weigh over 2,200 lbs, whereas a large male American Alligator typically weighs around 1,000 lbs. The biggest crocodiles are almost twice as long as the average person is tall!

2. When their mouths are closed, alligators keep their teeth hidden. With crocodiles, their bottom teeth protrude. American Alligators typically have between 74 and 80 teeth. Most crocodiles have between 60 and 70 teeth. Both species replace (grow) lost teeth throughout life.

3. Alligators have a wide, U-shaped snout, similar to a shovel. Crocodiles have a longer, V-shaped snout that is much more pointed at the tip.

4. Alligators and crocodiles vary in color. Alligators are usually gray and black. Crocodiles have olive and tan coloring.

5. Crocodiles are more aggressive than alligators. Crocs assert their dominance, while gators avoid conflict by walking away. However, both are dangerous predators that may attack if provoked. Keep your distance!

6. Both reptiles hunt prey underwater by sensing changes in water pressure.

7. Early European explorers in Florida called the reptile "El Lagarto" (The Lizard). English speakers later anglicized this into alligator.
