Many other animals also use these burrows after their builder abandons them. American alligators live about 50 years in the wild. After they are 4 feet long, alligators are safe from predators except humans and occasionally other alligators. Once on the verge of extinction, the American alligator has made a remarkable recovery due to strict conservation measures and extensive research.

It is no longer endangered except in scattered areas of its range. However, the federal government lists it as threatened because it is very similar in appearance to the American crocodile. Because the American crocodile is endangered, the government does not want hunters to confuse the two different types of animals. Hunting is allowed in some states but it is strictly controlled. The greatest threat is currently destruction of habitat; this includes water management systems and increased levels of mercury and dioxins in the water.

Since alligators can become large and will feed on almost anything, they pose a mild threat to humans. In Florida, where there is the greatest alligator population, there have been several reported deaths due to alligator attacks in recent years and human-alligator conflicts are common. Dogs and other pets are also sometimes killed. Alligators are hunted mostly for their skin, but also they are hunted for their meat.

Today, there is a multi-million dollar industry in which alligators are raised for the production of their meat and skin. Also, alligators are a tourist attraction, especially in Florida, where visitors enjoy nature tours to view and occasionally feed them. Skip to main content.

You may have heard that alligators can live forever, but die of starvation once their teeth stop re growing. This myth has been disproven. This important adaptation means that a new tooth can be ready for use as soon as the old tooth falls out.

You can see detailed images of this unusual arrangement here. Overall, crocodile teeth are longer and more pointed than those of alligators. Many crocodiles prey on large mammals — such as wildebeest — while alligators tend to mostly eat fish, turtles, and other smaller animals. This includes some teeth that are significantly enlarged — especially the fourth tooth on either side of the lower jaw counting from the snout.

These enlarged teeth sit in specialized grooves within the upper jaw. The position of these grooves differs between crocs and alligators. In alligators, the grooves are located inside of the upper jaw in the roof of the mouth. A young American crocodile Crocodylus acutus. Notice the visible groove on the upper jaw that houses its enlarged lower tooth.
