Alligators are large reptiles, members of the order Crocodylia. Alligators and crocodiles are, therefore, closely related, and people often confuse one with the other; however, these two reptiles are very different.An alligator is distinguished by its wide, rounded snout and black color. Also, all of its upper teeth can still be seen when its mouth is closed. Crocodiles, on the other hand, have narrow, pointed snouts, a grey-green color and only the fourth tooth on the lower jaw can be seen when the animal's mouth is closed, according to (FWC). SizeThere are two different types of alligator, and they vary in size.

The American alligator can grow up to 11.2 feet (3.4 meters) long and weight nearly half a ton (1,000 lbs. Or 454 kilograms), according to the. Chinese alligators are smaller, growing to around 4.6 to 4.9 feet (1.4 to 1.5 m) long and usually weighing only around 50 lbs. HabitatThe American alligator lives in the southern United States, from North Carolina to Texas, according to the Smithsonian Zoo. These gators can be found in slow-moving rivers, ponds, lakes and swamps.Chinese alligators live in eastern China, and they are confined to a small area in the Yangtze River basin near the Pacific Ocean, according to the.
They are traditionally found in rivers, lakes, ponds and swamps, but are now confined mostly to ditches and ponds on agricultural land. Much of their habitat has been converted to rice paddies. HabitsAlligators are social creatures and often stay in groups called congregations. These groups are typically seen basking in the sun or taking a swim. This is because alligators can't control their temperature internally. So, when they are cold, they sunbathe, and when they are hot, they go for a swim.Alligators also use water to hunt.
On land they are awkward, but in the water they can swim very quickly using their tails. This makes it easier for them to catch prey. American alligators can swim up to 20 mph (32.18 km/h) and run on land as fast as 11 mph (17.7 km/h), according to the.
DietAlligators aren't picky about what they eat. They are carnivores, so any type of prey is a meal to these reptiles. Alligators may eat fish, mollusks, birds, small mammals and other reptiles. Though carnivores usually only eat meat,. OffspringAlligators mate in June.
Males may fertilize several females in one mating season, according to the. Females are known to have only one mate each season. In July, the female alligator creates a nest from mud, plants and sticks in which she lays her eggs. The Chinese alligator can lay 10 to 50 eggs at a time, according to the. The American alligator lays a similar number.
After the hard-shelled eggs are laid, the mother alligator will cover them with more mud, sticks and plants.The temperature of the alligator's nest determines what sex the offspring will be, according to the. Females are produced when the temperatures are below 82.4 degrees Fahrenheit (28 degrees Celsius), and males are produced at temperatures above 91.4 F (33 C). A temperature of 87.8 F (31 C) will produce an even number of males and females.As the eggs incubate in the nest, the female will watch over them. In September, when the babies are ready to hatch, she will help them by removing debris covering the nest. She may also help the babies by breaking the shells with her mouth.As soon as they are born, the babies, called hatchlings, can go and catch their own food. Chinese hatchlings weigh only around 1.05 ounces (30 grams) and are around 8.3 inches (21 centimeters) long, according to the University of Michigan Museum of Zoology. American hatchlings are around 6 to 8 inches (15 to 20 cm) long.
After around two years, they leave their mother's protection to start their own families. Classification/taxonomyThe taxonomy of alligators, according to the (ITIS), is:. Kingdom: Animalia.

This category lists species at the highest risk for extinction. There are fewer than 130 Chinese alligators in the wild, according to the Saint Louis Zoo. Breeding programs in wildlife refuges and zoos have been successful, however.The American alligator population is doing well, and is listed as a.'
