What is the Biggest Alligator in the World?

There are currently two species of alligator in the world: The American Alligator and the Chinese alligator. Of these two, American alligators are the larger species, as they can grow up to 15 feet long (Chinese alligators typically grow to about 5 feet in length).

The largest American alligator on record is known as the Stokes Alligator; it was found in Alabama and measured at 15 feet, 9 inches long.

How Long Can an Alligator Live?

Alligators have fairly long lifespans; they live about 30 to 50 years on average. Of course, this is just an average range; some alligators die much earlier in life, while others live much longer. 

Alligators can live to be 80 years old or more. The oldest living alligator, named Muja, began living at the Belgrade Zoo in 1937; no one knows when he was born, but he was at least two years old when he arrived at the zoo.

How Many Teeth Does an Alligator Have?

According to the Smithsonian National Zoo, alligators can have anywhere between 74 and 80 teeth in their mouth at once.

An alligator’s teeth get worn down over time; as one tooth wears out, it falls out and is replaced by a new tooth. An alligator may have as many as 3,000 teeth total during its lifetime.

Conclusion

Alligators are water-loving reptiles that live in freshwater marshlands and swamps. They can live to be 50 years old or older and may go through as many as 3,000 teeth in their life.
