Husbandry and Breeding of the Crocodile Lizard (Shinisaurus crocodilurus) at Woodland Park Zoo, Seattle, Washington, USA.
Abstract
The "Day House" (reptile and amphibian unit) at the Woodland Park Zoo in Seattle, Washington, USA has been involved in the husbandry and breeding of Shinisaurus crocodilurus since 1993, producing a total of 59 offspring. The current Woodland Park Zoo Shinisaurus collection is housed entirely indoors and consists of 15 individuals. Individuals in Woodland Park Zoo’s Shinisaurus collection exhibit a shorter time to fertility and breeding cycles that do not correspond to behavior previously observed in wild and other captive populations. Woodland Park Zoo’s husbandry parameters and other data from the breeding program will be discussed.

Preliminary morphological comparisons between Chinese and Vietnamese Shinisaurus representatives showed no significant differences that would justify a separate taxonomic status of the single known Vietnamese population. Also first mitochondrial DNA sequence comparisons showed very low differentiation therefore, being likely to represent the same taxon. In addition, we provide further information about the habitat, and preliminary data concerning the reproduction and feeding ecology of Vietnamese S. crocodilurus. We further stress biogeographical and conservational aspects of the endangered species in Vietnam.
The Chinese crocodile lizard (Shinisaurus crocodilurus) is an unusual anguimorph lizard found mainly in China. Transect surveys estimate a total wild population of about 950 individuals in China. This is a dramatic decrease compared with previous surveys. At present, there are only eight areas of distribution. No Chinese crocodile lizards have been found in four former areas for several years. Investigations have demonstrated that poaching has contributed directly to the population decline. Habitat destruction, and in particular water flow, is the second most important factor. Mining, small scale dam construction, electro-fishing and poisoning of fish in the stream also contribute to population decline. Therefore, educating local people, punishing illegal poaching, and strengthening scientific research are urgent.
