Alligator Surprise, Florida, United States

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.
There is no measured average lifespan for an alligator. In 1937, a one year-old specimen was brought to the Belgrade Zoo in Serbia from Germany. It is now 76 years old. Although there are no valid records about its date of birth, this alligator in the Belgrade Zoo, officially named Muja (eng. Mooya), is considered the oldest alligator living in captivity.
