The Chinese stripe-necked turtle (Mauremys sinensis) or golden thread turtle, is a species of turtle in the family Geoemydidae. They are widely distributed in the subtropical regions of Taiwan.
Like many other Geoemydidae, this species hybridizes vigorously with related and not-so-closely related members of its family.
It is one of the two most commonly found species used for divination that have been recovered from Shang dynasty sites, despite the Shang capital being over 1000 km north of its modern-day distribution range. [3]
Chinese-stripe-necked turtles have a green body. As a juvenile, its carapace is grayish green and there are three distinctive ridges. As an adult, the color fades to a brown color and the two ridges gradually disappear. The plastron is ivory in color with small black spots. The male's tail is more coarse and long, while adult females will be larger than the males.
Chinese stripe-necked turtles prefer lowland waters such as ponds, canals, and slow-moving rivers. [1] Climate is very important when sustaining a risk of invasion, since the turtles become naturalized in areas with a suitable climate. [4]
The Chinese stripe-necked turtle is found in China (Hainan, Guangdong & Fujian), Taiwan and northern & central Vietnam. [1] There were hatchlings in the Torre Flavia wetland (coast of central Italy). This resulted in the idea that there is naturalization of the local population. [4]
Chinese stripe-necked turtles are protected by the CITES and IUCN, captive-breeding Chinese stripe-necked turtles are approved. Another reason that affects its population is the invasion of red-eared sliders. In Hong Kong, mainland China and Taiwan and in some other countries, it is a popular pet turtle.
In captivity, hybrids have been produced between this species and Japanese pond turtle, (Mauremys japonica) and the Chinese pond turtle, (Mauremys sinensis) as well as with a male Cyclemys (oldhami) shanensis . The supposed species Ocadia glyphistoma is a hybrid between a male M. sinensis and a female Vietnamese pond turtle, (Mauremys annamensis) a species nearly extinct in the wild. Ocadia philippeni was also shown to be of hybrid origin, a male M. sinensis with a female Cuora trifasciata . Both are either naturally occurring or bred for the pet trade. Any individuals that are available as pets therefore need to be kept separate from other members of the family to prevent hybridization.
After mating, the female turtle may lay 5-20 eggs that hatch about 60 days when needed.
The Geoemydidae are one of the largest and most diverse families in the order Testudines (turtles), with about 70 species. The family includes the Eurasian pond and river turtles and Neotropical wood turtles.
Oldham's leaf turtle is a species of turtle in the family Geoemydidae.
The golden coin turtle, also known commonly as the Chinese three-banded box turtle and the Chinese three-striped box turtle, is a species of turtle in the family Geoemydidae. The species is native to southern China. There are two recognized subspecies.
Asian box turtles are turtles of the genus Cuora in the family Geoemydidae. About 12 extant species are recognized. The keeled box turtle is often included in this genus, or separated in the monotypic genus Pyxidea. Genus Cuora is distributed from China to Indonesia and the Philippines, throughout mainland Southeast Asia, and into northern India and Bhutan.
The pond slider is a species of common, medium-sized, semiaquatic turtle. Three subspecies are described, the most recognizable of which is the red-eared slider, which is popular in the pet trade and has been introduced to other parts of the world by people releasing it to the wild. Hatchling and juvenile pond sliders have a green upper shell (carapace), yellow bottom shell (plastron), and green and yellow stripes and markings on their skin. These patterns and colors in the skin and shell fade with age until the carapace is a muted olive green to brown and the plastron is a dull yellow or darker. Some sliders become almost black with few visible markings. The carapace is oval with a bit of rounding and a central crest with knobs, but these features soften and fade with age, adults being smoother and flatter. For determining an adult slider's sex, males typically have much longer front claws than adult females, while females usually have shorter, more slender tails than males. Their lifespans range from 20 to 50 years.
The Vietnamese pond turtle or Annam leaf turtle is a species of turtle in the family Geoemydidae.
The Caspian turtle, also known as the striped-neck terrapin, is a species of turtle in the family Geoemydidae (=Bataguridae). It is found in west Asia, in Iran and central Turkey, northward to the Republic of Georgia and eastward to southwestern Turkmenistan, and in Iraq, Saudi Arabia, and Bahrain.
The red-necked pond turtle is a species of turtles in the family Geoemydidae endemic to China. It is most likely restricted to Guangxi and Guangdong provinces, although pre-historic skull remains have been found in northern Vietnam and Hainan. Other common names include Kwangtung river turtle and black-necked pond turtle.
Mauremys reevesii, commonly known as the Chinese pond turtle, the Chinese three-keeled pond turtle, or Reeves' turtle, is a species of turtle in the family Geoemydidae, a family which was formerly called Bataguridae. The species is native to East Asia.
The Fujian pond turtle is a possibly also naturally occurring intergeneric hybrid turtle in the family Geoemydidae. The Fujian pond turtle is produced in larger numbers by Chinese turtle farms as a "copy" of the golden coin turtle Cuora trifasciata. It appears to occur in China and Vietnam. Before its actual origin became known, it was listed as data deficient in the IUCN Red List.
Mauremys is a genus of turtles in the family Geoemydidae.
The Japanese pond turtle, also called commonly the Japanese pond terrapin and the Japanese pond tortoise, is a species of turtle in the family Geoemydidae endemic to Japan. Its Japanese name is nihon ishigame, Japanese stone turtle. Its population has decreased somewhat due to habitat loss, but it is not yet considered a threatened species.
The yellow pond turtle, is a medium-sized, semiaquatic turtle in the family Geoemydidae. This species has a characteristic broad yellow stripe extending behind the eye and down the neck; the carapace ranges in color from grayish brown to brown, and the plastron is yellow or orange with black blotches along the outer edges. It is native to East Asia, ranging from central Vietnam and Laos, north through the coastal provinces of south and central China, with insular populations known from Taiwan, Hainan and the Ryukyu Islands. Although populations in the southern Ryukyus are thought to be native, populations in the northern and central Ryukyus, as well as central Japan, are believed to have been introduced as a result of imports from Taiwan.
Mauremys pritchardi is an interspecific hybrid turtle in the family Geoemydidae. M. pritchardi, described to be from Myanmar, has been found in the wild in China and Japan, and is produced to some extent in Chinese turtle farms. It was listed as data deficient in the IUCN Red List before its actual origin became known.
"Mauremys" glyphistoma is a hybrid turtle in the family Geoemydidae. Originally described as a new species supposedly endemic to Guangxi/China; it was classified as Data Deficient in the IUCN Red List.
Philippen's striped turtle, "Mauremys" philippeni, has recently shown to be an intergeneric hybrid between a male Mauremys sinensis and a female Cuora trifasciata.
Terrapins are a group of several species of small turtle living in fresh or brackish water. Terrapins do not form a taxonomic unit and may not be closely related. Many belong to the families Geoemydidae and Emydidae.
Cyclemys is a genus of freshwater turtles, commonly referred to as Asian leaf turtles, from the family Geoemydidae. The genus occurs throughout Southeast and South Asia, and currently contains seven species.
Turtle farming is the practice of raising turtles and tortoises of various species commercially. Raised animals are sold for use as gourmet food, traditional medicine ingredients, or as pets. Some farms also sell young animals to other farms, either as breeding stock, or more commonly to be raised there to a larger size for subsequent resale.
The Balkan terrapin or western Caspian terrapin is a species of terrapin in the family Geoemydidae. It is found in the eastern Mediterranean region. While technically omnivorous, the terrapins are known to prefer meat. They can grow to 25 cm in carapace length, although hatchlings are usually only 3 to 4 cm in length.
