DistributionChina (areas around the lower Yangzi River in Jiangau, Zhejiang, Anhui)

Type locality: "Chinkiang" [=Zhenjiang], Kiangsu Province, People's Republic of China; reported as "Wuhu, Anhwei" Province, by Pope 1935, Nat. Hist. Cent. Asia, Am. Mus. Nat. Hist. 10:65.

TypesSyntype: MNHN-RA 6494 (MNHN catalogue indicated syntype not holotype) 
Diagnosis 
Comment“There is confusion concerning the type locality. Fauvel 1879 based his description on 6 specimens: the first specimen (Fauvel 1879:28), from Wuhu, was dissected and later mounted for display at the Shanghai Museum. He then sought "... another specimen to be forwarded to Paris, in order to have the species named. This appeal was duly responded to on the 3rd of October last, when we received a second specimen from Chinkiang." Four additional specimens, were purchased in Shanghai (Fauvel 1879:29); two live specimens reputed to have been collected in Poyang Lake, Kiangsi Province, and two skins with skulls attached lacking exact provenience. Presumably the one shipped to Paris, clearly intended to be the holotype, was the specimen from Chinkiang (present English transliteration is Zhenjiang, Chinkjang, or Chenchiang). It arrived at the MNHN in good order (Fauvel 1879:36f). Because it possesses morphological characteristics superficially reminiscent of caimans, Deraniyagala 1947 placed the Chinese alligator in a new genus, Caigator. That placement has not been supported by any later author, since some of those characteristics are present in varying degrees in the American alligator” (after King & Burke 1989).

Genomics: this is one of the species selected by the Genome 10K consortium (G10K) for complete genome sequencing. 
EtymologyNamed after its occurrence in China.
