Alligator

General Info :

An alligator is a crocodilian in the genus Alligator of the family Alligatoridae. There are two living alligator species: the American alligator (Alligator mississippiensis) and the Chinese alligator (Alligator sinensis). In addition, several extinct species of alligator are known from fossil remains. Alligators first appeared during the Oligocene epoch about 37 million years ago.
The name alligator is an anglicized form of el lagarto, the Spanish term for "the lizard", which early Spanish explorers and settlers in Florida called the alligator.

Physique :

A large adult American alligator's weight and length is 360 kg (790 lb) and 4.0 m (13.1 ft) long, but can grow to 4.4 m (14 ft) long and weigh over 450 kg (990 lb). The largest ever recorded was found in Louisiana and measured 5.84 m (19.2 ft). The Chinese alligator is smaller, rarely exceeding 2.1 m (6.9 ft) in length. Alligators have an average of 75 teeth.

Diet :

The type of food eaten by alligators depends upon their age and size. When young, alligators eat fish, insects, snails, crustaceans, and worms. As they mature, progressively larger prey is taken, including larger fish such as gar, turtles, various mammals, particularly nutria and muskrat, as well as birds, deer and other reptiles. They will even consume carrion if they are sufficiently hungry. In some cases, larger alligators are known to ambush dogs, Florida panther and black bears, making it the apex predator throughout its distribution. 

Distribution :

American alligators are found in the southeast United States: all of Florida and Louisiana, the southern parts of Georgia, Alabama and Mississippi, coastal South and North Carolina, Eastern Texas, the southeast corner of Oklahoma and the southern tip of Arkansas. According to the 2005 Scholastic Book of World Records, Louisiana is the state with the largest alligator population. The majority of American alligators inhabit Florida and Louisiana, with over a million alligators in each state.
The Chinese alligator currently is found only in the Yangtze River valley and is extremely endangered, with only a few dozen believed to be left in the wild. Indeed, far more Chinese alligators live in zoos around the world than can be found in the wild.
