Articles relating to the genus Alligator. The two extant species are the American alligator (A. mississippiensis) and the Chinese alligator (A. sinensis). Additionally, several extinct species of alligator are known from fossil remains.
In the same year, 50 captive-bred crocodiles were released into the wild to help boost the population. Support from local people is crucial for the species' survival. [168] The American alligator has also undergone serious declines from hunting and habitat loss throughout its range, threatening it with extinction.
Unverified reports suggest lengths of up to 6 m (20 ft) for the black caiman and 5.84 m (19.2 ft) for the American alligator, reaching weights of over 1,000 kg (2,200 lb), but such lengths are probably exaggerated. Deinosuchus (fossil specimen), one of the largest crocodilians to ever exist.
It and the American alligator (A. mississippiensis) are the only living species in the genus Alligator of the family Alligatoridae. Dark gray or black in color with a fully armored body, the Chinese alligator grows to 1.5–2.1 metres (5–7 ft) in length and weighs 36–45 kilograms (80–100 lb) as an adult.
Florida honored the American alligator in 1987, but the Gators have titled the University of Florida's teams since 1911.
