Pelodiscus
''Pelodiscus'' is a genus of turtles in the family Trionychidae, the softshells. Based on genetic and morphological analysis there are seven valid species. They are native to Eastern Asia, ranging from the Amur region, south through China and Korea, as far south as Vietnam. Populations in Japan are thought to likely originate from historic human introductions. Phylogenetic studies have recovered a high diversity of ''Pelodiscus'' genotypes in China, some of which may correspond to distinct species. However, the millennia-old practice of farming ''Pelodiscus'' for consumption, especially in large-scale turtle farms since the late 20th century, is thought to threaten these lineages due to hybridization with farmed individuals.

Chinese Softshell Turtle
The Chinese softshell turtle (''Pelodiscus sinensis'') is a species of softshell turtle that is native to mainland China (Inner Mongolia to Guangxi, including Hong Kong) and Taiwan, with records of escapees—some of which have established introduced populations—in a wide range of other Asian countries, as well as Spain, Brazil and Hawaii. Populations native to Northeast China, Russia, Korea and Japan were formerly included in this species, but are now regarded as separate as the northern Chinese softshell turtle (''P. maackii''). Furthermore, localized populations in Guangxi and Hunan (where the Chinese softshell turtle also is present), as well as Vietnam, are recognized as the lesser Chinese softshell turtle (''P. parviformis'') and Hunan softshell turtle (''P. axenaria''). The Chinese softshell turtle is a vulnerable species, threatened by disease, habitat loss, and collection for food such as turtle soup. Additionally, millions are now farmed, especially in China, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trionychidae
Trionychidae is a family of turtles, commonly known as softshell turtles or simply softshells. The family was described by Leopold Fitzinger in 1826. Softshells include some of the world's largest freshwater turtles, though many can adapt to living in highly brackish waters. Members of this family occur in Africa, Asia, and North America, with extinct species known from Australia. Most species have traditionally been included in the genus '' Trionyx'', but the vast majority have since been moved to other genera. Among these are the North American '' Apalone'' softshells that were placed in ''Trionyx'' until 1987. Characteristics Turtles of the family Trionychidae are called "softshell" because their carapaces lack horny scutes (scales), though the spiny softshell, '' Apalone spinifera'', does have some scale-like projections, to which its common name refers. The carapace is leathery and pliable, particularly at the sides. The central part of the carapace has a layer of solid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelodiscus Maackii
The Amur softshell turtle (''Pelodiscus maackii)'', also commonly known as the northern Chinese softshell turtle, is a species of turtle in the family Trionychidae. The species is native to Asia. Geographic range ''Pelodiscus maackii'' is found in the Russian Far East, northeastern China, Korea, and Japan. It is possible that the Japanese populations are the result of ancient introductions by humans. Description An aquatic species, ''Pelodiscus maackii'' may attain a straight carapace length of . Breeding In China specifically, the breeding of the closely-related Chinese softshell turtle (''Pelodiscus sinensis'') has been done for over 2,400 years, and the production has come to 340,000 annually due to the demand. Etymology The specific name, ''maackii'', is in honor of Russian naturalist Richard Maack Richard Otto Maack (; 4 September 1825 – 25 November 1886) was a Russian naturalist, geographer, and anthropologist. He is most known for his exploration of the Russ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelodiscus Axenaria
The Hunan softshell turtle (''Pelodiscus axenaria'') is a species of turtle in the family Trionychidae, the softshells.

It is found in Taoyuan, Pingjiang, Rucheng, Lingling, and Shaoyang counties of Hunan province (Zhou, Zhang & Fang, 1991). The meaning of the epithet "''axenaria''" is unknown; Gong et al. (2022) suggested that it might be a misspelling of ''arenaria'', which means "of sand" in Latin.

Pelodiscus Parviformis
The lesser Chinese softshell turtle (''Pelodiscus parviformis'') is a species of turtle in the family Trionychidae. It is endemic to China, where it inhabits a small range in Guangxi and Hunan provinces. Populations of this species in Vietnam and Hainan are now considered to belong to a separate species, the spotted softshell turtle (''P. variegatus''). There is some controversy within researchers over whether or not ''P. parviformis'' is a valid species. Yang et al. (2011) deemed it a valid species. Reptile Database commented that due to a lack of a revised diagnosis in this study, this species is still somewhat of unclear status. It has been proposed that this species be considered as Critically Endangered on the IUCN Red List The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological ... d ...

Pelodiscus Huangshanensis
The Huangshan softshell turtle or horse-hoof softshell turtle (''Pelodiscus huangshanensis'') is a species of turtle in the family Trionychidae. It is endemic to China, where it is found only in southern Anhui Province, in the Huangshan range. Taxonomy Prior to 2021, populations of this species were considered conspecific with the more widespread Chinese softshell turtle (''P. sinensis''), which was thought to be the only native softshell turtle in the province. However, local people knew about the existence of this species over a millennium prior. Folk songs and poems noted a second form of softshell turtle in the Huangshan range, referred to as the "horse-hoof softshell turtle" or ''mǎ tí biē'' (马蹄鳖). Phylogenetic evidence of these populations found them to be a distinct species most closely related to the Hunan softshell turtle (''P. axenaria'') as well as an undescribed ''Pelodiscus'' from Jiangxi. It was accepted as a distinct species by the Turtle Taxonomy Workin ... [...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, "" Turtle farms primarily raise freshwater turtles (primarily, Chinese softshell turtles as a food source and sliders and cooter turtles for the pet trade);Links from 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 in Australia's Torres Strait Islands folded after a few years of operation, and the one in Réunion has been converted to a public aquarium (K� ...

Johann Friedrich Von Brandt
Johann Friedrich von Brandt (25 May 1802 – 15 July 1879) was a German-Russian natural history, naturalist, who worked mostly in Russia. Brandt was born in Jüterbog and educated at a Gymnasium (school), gymnasium in Wittenberg and the Humboldt University of Berlin, University of Berlin. In 1831 he emigrated to Russia, and soon was appointed director of the Zoological Museum of the St Petersburg Academy of Sciences. Brandt encouraged the collection of native animals, many of which were not represented in the museum. Many specimens began to arrive from the expeditions of Nikolai Alekseevich Severtzov, Severtzov, Nikolai Przhevalsky, Przhevalsky, Aleksandr Fyodorovich Middendorf, Middendorff, Leopold von Schrenck, Schrenck and Gustav Radde. He described several birds collected by Russian explorers off the Pacific Coast of North America, including Brandt's cormorant, red-legged kittiwake and spectacled eider. As a paleontologist, Brandt ranks among the best. He was also an entomo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...
