Description

An alligator is a crocodilian in the genus Alligator of the family Alligatoridae. There are two living alligator species: the American Alligator and the Chinese Alligator. They are closely related to crocodiles.

Proportions

According to the Everglades National Park website, the largest alligator ever recorded in Florida was 17 feet 5 inches long (5.3 meters). The largest alligator ever recorded measured 19 feet 2 inches (5.8 meters) and was found on Marsh Island, Louisiana. Few of the giant specimens were weighed, but the larger ones could have exceeded a ton in weight.

Personality

Alligators are solitary, territorial animals. The largest of the species (both males and females), will defend prime territory; smaller alligators have a higher tolerance of other alligators within a similar size class. Although alligators have heavy bodies and slow metabolisms, they are capable of short bursts of speed that can exceed 30 miles per hour. Alligators' main prey are smaller animals that they can kill and eat with a single bite. Alligators may kill larger prey by grabbing it and dragging it in the water to drown. Alligators consume food that cannot be eaten in one bite by allowing it to rot or by biting and then spinning or convulsing wildly until bite size pieces are torn off. This is referred to as the "death roll."

Things to Note

Alligators are characterized by a broader snout and eyes more dorsally located than their crocodile cousins. Both living species also tend to be darker in color, often nearly black (although the Chinese alligator has some light patterning.) Also, in alligators only the upper teeth can be seen with the jaws closed (in contrast to true crocodiles, in which upper and lower teeth can be seen), though many individuals bear jaw deformities which complicate this means of identification. The eyes of an alligator glow red when a light is shined on them. This fact can be used to find alligators in the dark.

Alligators are opportunistic feeders, eating almost anything they can catch. When they are young they eat fish, insects, snails, and crustaceans. As they grow they take progressively larger prey items, including: larger fish such as gar, turtles, various mammals, birds, and other reptiles. They will even consume carrion if they are sufficiently hungry. Adult alligators can take razorbacks and deer and are well known to kill and eat smaller alligators. In some cases, larger alligators have been known to hunt the Florida panther and bears, making it the apex predator throughout its distribution. As humans encroach onto to their habitat, attacks on humans are not unknown, but few. Alligators, unlike the large crocodiles, do not immediately regard a human upon encounter as prey. Unfortunately, human deaths caused by alligators have increased. While there were only 9 fatal attacks in the U.S.A. from the 1970s to the 1990s, 11 people were killed by alligators from 2001 to 2006. More deaths occurred in this 5-year period than did in the previous 30. For a long time people have been taught that alligators fear humans, which is true, but this has led some people to be foolhardy and enter the animal's habitat in ways that provoke aggression.
