Alligators are semi-aquatic, sharp-toothed reptiles (order: Crocodylia, family: Alligatoridae, genus: Alligator.) There are two known living species in the Alligator genus, the American Alligator (Alligator mississippiensis) and the Chinese Alligator (Alligator sinensis.)
There are many extinct species in the Alligatoridae family, but more specifically, the Alligator genus has four known extinct species. These species are the mcgrewi, mefferdi, olseni, and the prenasalis.
These animals are both intriguing and powerful. For example, the American Alligator has the strongest laboratory-tested bite of any animal. The bite of this alligator measures over 9,400 newtons!
American Alligator Facts
The American Alligator can weigh a mere 170 pounds all the way up to a hefty 800 pounds! They grow to approximately 13 feet long. These gators are native only to the United States and inhabit Florida, Louisiana, Georgia, Alabama, Mississippi, South Carolina, North Carolina, Texas, Oklahoma, and Arkansas.
While Florida is especially well-known for its alligator population, Louisiana is actually home to a larger population of these lizard giants, with numbers reaching approximately 1.5 to 2 million gators.
Florida holds the title of the only place in the world inhabited by both alligators and crocodiles. Louisiana and Florida have a large number of marshes, rivers, lakes, and swamps, all of which are environments perfect for alligators.
Where American Alligators Live
Chinese Alligator Facts
The Chinese Alligator, native only to China, is considerably smaller than its American counterpart. It also differs in that its snout is tapered and turns up at the end.
The Chinese Alligator's teeth aren't as sharp as its American cousin's, but the shape of the teeth allows for better crushing. This will enable it to feed on mollusks such as clams and snails (these make up a large part of this alligator's diet.)
Adults reach an average of five feet in length and weigh approximately 85 pounds. Another significant difference is that the Chinese Alligator is fully armored (very few crocodilian species have an exoskeleton.)
Are Alligators Endangered?
Despite the Chinese Alligator's protective armor, it is critically endangered, with fewer than 200 remaining in the wild.
Their shrinking population is due to a number of factors, including:
- Inadvertent poisoning (they feed on rats that have been poisoned)
- Human consumption (many parts of a gator's body are used as tonics and cures in traditional Chinese medicine)
- Encroachment onto their natural habitat (rice paddies have been built in areas previously inhabited by the alligators, considerably shrinking the areas where they're able to live.)
American Alligators were also on the endangered species list at one time. They were first classified as an endangered species in 1967 by the US Fish & Wildlife Service. Due to legal protection, the population of gators boomed, and they were taken off the list just 20 years later.
Chinese Alligators are currently being bred in zoos and being released in the wild (in their native region of China.) Perhaps this reintroduction, paired with the fact that American Alligators showed tremendous success in increasing the size of their population, shows hope for the future of the Chinese Alligator.

gators are a very interesting type of animal
I am kind of that person that like to hang out with dangerous
I may seem like I wont go near a snake or gator but my brother owns a gator and 3 snakes I like to play with them

We always have a gator in our South Carolina lagoon who suns in our yard. All of a sudden a new guy has appeared. Its coloration is different...has very distinct light-colored stripes on its body. Wonder who he/she is?

Interesting. There is some contention regarding the most powerful bite on the planet with most people agreeing the huge salt-water croc of Australia having the greatest crushing force measured (I guess it would be a toss-up with a huge Alligator), But there is also general agreement the Great White Shark would probably win - it is yet to be measured.
The strongest among land mammals is the Polar Bear.

Gators scare me. I did not know there were so many!

Great info. It was an interesting read. I actually tried deep-fried alligator meat once. Now knowing that they're on the endangered species list, I do feel guilty for eating that alligator po-boy. :(

Well done, I love articles where I learn new things. Thanks for the great writing.

Oh I love gators. I think they are majestic creatures. Big lizards with attitude! They really are beautiful animals. Powerful, yet in the water they're amazingly graceful. My favorite reptiles. I actually have two in my backyard here in Central Florida!
Voted up and awesome

Very informative. I've never heard of the Chinese alligator. It's so much smaller than its American counterpart. Hopefully, they are successful at increasing its population.
