The Yunnan box turtle (Cuora yunnanensis) is a species of turtle in the family Geoemydidae (formerly Bataguridae). It is believed to be endemic to Yunnan, China (in Kunming and Huize) and was suspected to be extinct since the early 20th century; the last verified specimen was collected in 1940. [4]

In 2004, a living female appeared from the pet trade in Kunming; one year later, a male from the same source and again one year later another female were found there. The validity of these specimens was doubted and many believed they were intentionally produced hybrids, [5] a common technique in China to produce turtles that get high prices.

In 2007, He et al. sampled the three living specimens and gave the genetic proof that all three living specimens are indeed C. yunnanensis and not hybrids. In 2008, Kadoorie Conservation China, a department of Kadoorie Farm and Botanic Garden, together with the Kunming Institute of Zoology and Chinese Academy of Sciences, discovered a small wild population. The distribution of this species remains unclear, but due to its value, it is heavily sought after. Protection measures are needed to save this probably highly endangered species from its return onto the IUCN list of extinct animals.

The Vietnamese three-striped box turtle or green rice turtle is a species of the Southeast Asian genus Cuora. It is distributed from the extreme southern part of the Chinese Guangxi province southwards to central Vietnam and central Laos. This species reaches up to 30 cm straight carapace length and is thus the largest Cuora species. Due to demand of traditional Chinese medicine, this species is nearly extinct in the wild, but is readily bred on Chinese turtle farms. Extremely high prices are paid for this species in China. It can be distinguished from Cuora trifasciata by its larger size and generally more oval or rounder shell, which is usually also flatter, a white, pink, or orange chin, and head coloration with an orange-brownish-olive dorsal head pattern and less black pigment.

<span class="mw-page-title-main">Box turtle</span> Common name for several species of turtle

Box turtle is the common name for several species of turtle. It may refer to those of the genus Cuora or Pyxidea, which are the Asian box turtles, or more commonly to species of the genus Terrapene, the North American box turtles. They are largely characterized by having a shell shaped like a dome, which is hinged at the bottom, allowing the animal to close its shell tightly to escape predators. Furthermore, the two genera are very different in habitat, behavior and appearance, and are not even classified in the same family. Even though box turtles became very popular pets, their needs in captivity are complex and the capture of turtles can have serious detrimental effects on the wild population.
