This lizard gets its name from the appearance of its tail, which has an enlarged pair of scales running most of its length, similar to the tail of a crocodile. It is an endangered species due to habitat loss as well as being harvested for the pet trade and Chinese medicine. It was thought to inhabit only one mountainous province of China, where it lives in and around clear pools of slow-moving, shallow water. However, in 2003 a population was also discovered in the Quang Ninh Province of north-eastern Vietnam.
