The American Alligator has a large, slightly rounded body, with thick limbs, a broad head, and a very powerful tail. They generally have an olive, brown, gray or nearly black color with a creamy white underside. Algae-laden waters produce greener skin, while tannic acid from overhanging trees can produce often darker skin.
[2] Adult male alligators are typically 11.2 to 14.7 ft (3.4 to 4.5 m) in length, while adult females average 8.2 to 9.8 ft (2.5 to 3.0 m).
[3][4][5] One American Alligator allegedly reached a length of 19 feet, 2 inches (5.8 meters),
[6] which would make it the largest recorded. The tail, which accounts for half of the alligator's total length, is primarily used for aquatic propulsion. The tail can also be used as a weapon of defense when an alligator feels threatened. Alligators travel very quickly in water and while they are generally slow-moving on land, alligators can lunge short distances very quickly. They have five claws on each front foot and four on each rear foot. American Alligators have the strongest bite of any living animal, measured at up to 9452
newtons in laboratory conditions.

Some alligators are missing an inhibited
gene for
melanin, which makes them
albino. These alligators are extremely rare and practically impossible to find in the wild. They could survive only in captivity. Like all
albino animals, they are very vulnerable to the sun and predators.
