Chinese 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. It is one of the two most commonly found species used for divination that have been recovered from Shang dynasty sites. Geographic range ''Mauremys reevesii'' is native to China and Korea, and is thought to have been introduced to Japan and Taiwan in historic times; it was previously thought to be native to both these regions. The species is thought to have been introduced to Japan from the Korean Peninsula near the end of the 18th century. Introduced populations of ''M. reevesii'' may serve as a threat to the native turtles of these regions due to its propensity for hybridization.ATTWG (2000) Habitat and behaviour ''M. reevesii'' is semiaquatic, and basks in the sun on rocks or logs and can often be found leaving water to ...

Red-necked Pond Turtle
The red-necked pond turtle (''Mauremys nigricans'') 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. Anatomy and morphology A megacephalic form of the red-necked pond turtle exists, commonly called 'dumb-head'. This form is rarer than the smaller headed individuals. This species has strong sexual dimorphism Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most ani ... with a significant size difference between males and females.

Yellow Pond Turtle
The yellow pond turtle (''Mauremys mutica''), is a medium-sized (to 19.5 cm), 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. This species inhabits ponds, creeks, swamps, marshes, and other bodies of shallow, slow-moving water. It is omnivorous, feeding on insects, fish, tadpoles, and vegetable matter such as leaves and seeds. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turtle Farm
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.Darrell Senneke,Declared Turtle Trade From the United States - intro page Turtle farms primarily raise freshwater turtles (primarily, Chinese softshell turtles as a food source and Trachemys, sliders and Pseudemys, cooter turtles for the pet trade);Links froDeclared Turtle Trade From the United States - breakdown by species/ref> therefore, turtle farming is usually classified as aquaculture. However, some terrestrial tortoises (e.g. ''Cuora mouhotii'') are also raised on farms for the pet trade. Only three serious attempts are believed to have been made to farm sea turtles. Only one of them, in Cayman Islands, continues to operate. The one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turtle Genera
Turtles are an order of reptiles known as Testudines, characterized by a special shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. Turtle shells are made mostly of bone; the upper part is the domed carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scales made of keratin, the material of hair, horns, and claws. The carapace bones develop from ribs that grow sideways and develop into broad flat plates th ...

Sterility (physiology)
Sterility is the physiological inability to effect sexual reproduction in a living thing, members of whose kind have been produced sexually. Sterility has a wide range of causes. It may be an inherited trait, as in the mule; or it may be acquired from the environment, for example through physical injury or disease, or by exposure to radiation. Sterility is the inability to produce a biological child, while infertility is the inability to conceive after a certain period. Sterility is rarely discussed in clinical literature and is often used synonymously with infertility. Infertility affects about 12-15% of couples globally. Still, the prevalence of sterility remains unknown. Sterility can be divided into three subtypes natural, clinical, and hardship. Natural sterility is the couple’s physiological inability to conceive a child naturally. Clinical sterility is natural sterility for which treatment of the patient will not result in conception. Hardship sterility is the inability to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mauremys Pritchardi
''Mauremys pritchardi'' is an interspecific hybrid turtle in the Family (biology), family Geoemydidae. ''M. pritchardi'', described to be from Myanmar (where neither of the parental species occurs apparently), 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. The parents of this hybrid are the Chinese pond turtle (''Mauremys reevesii'' ) and the Yellow pond turtle, Asian yellow pond turtle (''Mauremys mutica''). While it is not unusual for perfectly valid geoemydid species to arise from hybridization, recognition as a species would require that the hybrids be fertile and constitute a phenotypically distinct and self-sustaining lineage. This does not yet appear to be the case in this "species" as recently (Kosukawa et al. 2006) a population of these turtles has been found in Japan. The hybrid offspring are perfectly fertile, which is not t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cuora Cyclornata
The Vietnamese three-striped box turtle or green rice turtle (''Cuora cyclornata'') is a species of the Southeast Asian genus '' Cuora'' (family Geoemydidae). 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. Subspecies Recognized subspecies: Blanck, T., Protiva, T., Zhou, T., Li, Y., Crow, P., and Tiedemann, R. (2017). New subspecies of ''Cuora ...

Golden Coin Turtle
__NOTOC__ The golden coin turtle or Chinese three-striped box turtle (''Cuora trifasciata'') is a species of turtle endemic to southern China. Distribution The species is distributed in China, but only on the island of Hainan (it is extirpated from the mainland Guangdong, Guangxi, and Fujian provinces), as well as Hong Kong. The populations from other parts of Vietnam and Laos are now regarded a separate species, the Vietnamese three-striped box turtle (''C. cyclornata''). Description This species has three distinct black stripes on its brown carapace, with a yellow, slightly hooked upper jaw and a yellow stripe extending from the back of the mouth. The plastron is mostly black with a yellow border. Diet In Hong Kong, this species feeds on fish, frogs, and carrion, but remains of crabs, snails, and insects have been found in its feces. It can grow up to 25 cm (10 in). Taxonomy It hybridizes very easily with its relatives in captivity and in the wild, and hybrids may ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
