The Chinese Dragon, also known as the loong, long or lung, is a legendary creature in Chinese mythology, Chinese folklore, and Chinese culture at large. Chinese dragons have many animal-like forms such as turtles and fish, but are most commonly depicted as snake-like with four legs. Academicians have identified four reliable theories on the origin of the Chinese dragon: snakes, Chinese alligators, thunder worship and nature worship. They traditionally symbolize potent and auspicious powers, particularly control over water.

The Chinese alligator, also known as the Yangtze alligator, China alligator, or historically the muddy dragon, is a crocodilian endemic to China. It and the American alligator 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. It brumates in burrows in winter and is nocturnal in summer. Mating occurs in early summer, with females most commonly producing 20–30 eggs, which are smaller than those of any other crocodilian. The species is an opportunistic feeder, primarily eating fish and invertebrates. A vocal species, adults bellow during the mating season and young vocalize to communicate with their parents and other juveniles. Captive specimens have reached age 70, and wild specimens can live past 50.
