American Alligator

American Alligator

Scientific Name: Alligator mississippiensis
Common Names: American Alligator, Mississippi Alligator

Maximum adult length: 4 metres (13.1 feet)


N.B. Exceptionally large specimens can be found in all species of crocodilian.


The American alligator is native to the southeastern United States. Though often confused with various crocodile species, the American alligator can be distinguished by its rounded snout, and by the fact that when the jaws are closed, none of the lower teeth are visible. The average length for an adult female is around 3 metres (9.8 feet), and for a male 3.4 to 4.6 metres (11.1 to 15 feet). They prefer slow moving relatively deep water. This species does not have a salt gland, but they can tolerate salt water for brief periods.

At the zoo

We are currently home to a male American, called Albert, and a female called Daisy.


Daisy is a long-time resident at Crocodiles of the World and was a star of Channel 5’s Croc Man documentary series.


Albert, a 20-year-old, male American alligator came to us from another zoological collection and arrived on 25 March 2013. At 3.08 metres (10.1 feet) in length, Albert is ever so slightly longer than Hugo, our male Siamese crocodile. But weighing a formidable 180 kg (397 lbs.), he has a significantly broader and more heavy set build.


Daisy and Albert produced a clutch of eggs in Spring 2013, with the eggs being laid on 20 June 2013 and later hatching between 31 August 2013 and 3 September 2013.
