This article is intended to serve as a brief summary of this species of  critically endangered crocodilian that inhabits parts of China.*

 

 

The Chinese 'sibling' of the American alligator, which might be loosely considered a dwarf version of it, is one of the most endangered crocodilians in the world. There are far more of them in captivity than in the wild, where their number was estimated to be fewer than 130 in 2002. Formerly more widely distributed over the Lower Yangtze River area, it is now entirely or mostly restricted to a small area of a single province. A number of factors, including habitat loss, natural disasters, destruction by humans (hunting and industry encroachment), low reproductivty and fragmented population distribution, contribute to the complex threat to the survival of this species.

 

Like its American relative, the alligator is a member of the Family Alligatoridae, a group in scientific classification that is distinct from the crocodiles, and it inhabits temperate zone, living in wetlands and ponds, many in close proximity to agriculture, a situation that generates confilct between human and animal.A Chinese alligator at the Cincinnati Zoo.

 

Unlike the American species, it lives at relatively high northern latitude, and spends much of the year brumating (a kind of reptile hibernation in low temperatures) in complex burrow systems. Similarly, the American alligator brumates in the northerly reaches of its range (i.e. North Carolina) and excavates a burrow for such use. The Chinese reptile becomes active when the warmer temperatures occur, usually starting in May, when it emerges from its burrow nocturnally. Courtship begins in June, and nesting takes place during July and August. Ten to forty eggs may be laid in a mound of vegetation constructed by the mother alligator. Like her North American relative, she will tenaciously guard her nest; the image below depicts such behavior.

The Chinese alligator body much resembles the American's, an notable exception being that the former reaches a maximum length of 6.6ft/2m, about half that of the latter. Furthermore, it features an array of tiny "specks", alternating light- and dark-colored dots or "splotches", about its hide far more prominently than that of the American. The Chinese version's snout and head also appears more blunt and its hide is rougher, making it undesirable to the leather goods industry.

The Association of Zoos & Aquariums' (AZA's) conservation program has distributed this species thorughout the USA for exhibit and observation at various zoos, such as at the Cincinnati Zoo in Ohio, pictured above.
