Shinisaurus crocodilurus
A semiaquatic lizard living along streams in southern China and north-eastern Vietnam. Rows of raised bony scales running down the back and tail recall a crocodile, and give the animal its name. It reaches 40-46 cm and is brown, some individuals marked with red or yellow.
The Chinese crocodile lizard (Shinisaurus crocodilurus) is a semiaquatic lizard confined to Guangxi and Guangdong in southern China and to north-eastern Vietnam. It is the only living species in the family Shinisauridae and the genus Shinisaurus, the survivor of a lineage whose fossil record reaches back to the Early Cretaceous more than 120 million years ago. It lives along streams in subtropical evergreen broadleaf forest at 200-760 m, basking on rocks and on branches overhanging the water and diving in to escape danger. That habit has earned it the local name luoshuigou, the dog that falls in the water, while its long motionless spells have given it the name dashuishe, the great sleeping snake. It is a sit-and-wait predator, taking insects, earthworms, tadpoles and small fish. Habitat destruction from dams and mining, bycatch from poison and electrofishing, and illegal collection for the pet trade have caused a steep decline, and the IUCN assesses it as Endangered.

Nomenclature follows global taxonomic authority databases.
Listed in Washington Convention Appendix I since January 2, 2017. Constitutes an international rare wild fauna and flora species under the Law for Conservation of Endangered Species of Wild Fauna and Flora; domestic transfer and equivalent transactions require individual registration certificates. Sale and transfer of individuals lacking registration certificates constitute violations of this law. Does not fall under the specified animals listed in the schedule of the Animal Welfare and Management Law Enforcement Ordinance, nor is it designated as a specified alien species under the Alien Species Act. Originally listed in Appendix II on January 18, 1990, it was transferred to Appendix I in 2017. In the People's Republic of China, it is designated as a Grade 1 Key Protected Wild Animal.

In the wild it lives at 200-760 m, where summer air temperatures peak at 38 C, winters fall to -4 C and the day-night swing is wide. In captivity hold the water at 19-27 C, then from around November lower it to about 15 C for a hibernation of three to four months; this winter cooling is regarded as essential for captive breeding. Its habitat receives some 2,000 mm of rain a year and is almost permanently shrouded in mist, so keep humidity high.
Semiaquatic, so use an aquaterrarium that combines land and water. In one successful breeding setup a cage of about 91 x 36 x 36 cm gave a third of its floor to a water basin roughly 6 cm deep, with branches arranged to overhang the water. Always provide basking branches and retreats that let the animal hide, such as a hollow log or loose bark.
A sit-and-wait predator that watches for prey from branches overhanging the water, taking insects, earthworms, tadpoles, small fish and frogs. In captivity crickets, mealworms and earthworms form the bulk of the diet. Juveniles take the same foods in smaller sizes.
Strongly territorial: in the wild a single lizard usually occupies an entire pool or stretch of stream. Dominance is settled by gaping, tail-swinging and a push-up display in which the forelimbs are straightened. It does not tolerate company, so house it singly except when breeding.
It has been listed on CITES Appendix I since 2 January 2017. Under Japan's Species Conservation Act it is an internationally endangered species, and transferring one within Japan requires an individual registration certificate; trading or transferring an unregistered animal breaches that Act. It is neither a specified animal nor an invasive alien species under Japanese law. It was placed on Appendix II on 18 January 1990 and moved to Appendix I in 2017 as poaching and international trade increased. Although its lineage is close to the helodermatid lizards, a 2023 proteomic analysis of its mandibular glands found no toxin-related proteins, so it is not venomous. Wild-caught animals have repeatedly been reported sold as captive-bred, so always check the registration certificate and the origin. Rearing the young is difficult and genuinely captive-bred animals rarely reach the market.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The average lifespan of Chinese Crocodile Lizard is Well over 10 years in captivity; one imported male was estimated by its keeper at more than 15 years. With proper care and nutrition, they can live a long and healthy life.
Chinese Crocodile Lizard typically reaches Total length 40-46cm, males slightly larger as an adult. Size may vary depending on care conditions and individual genetics.
