Japanese Pond Turtle
The Japanese pond turtle (''Mauremys japonica''), also called commonly the Japanese pond terrapin and the Japanese pond tortoise, is a species of turtle in the family Geoemydidae endemic to Japan Japan ( ja, 日本, or , and formally , ''Nihonkoku'') is an island country in East Asia. It is situated in the northwest Pacific Ocean, and is bordered on the west by the Sea of Japan, while extending from the Sea of Okhotsk in the north .... 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. This species is known to hybridize with the Chinese pond turtle, the Chinese stripe-necked turtle, and the Chinese box turtle (and possibly other Geoemydidae) in captivity. As these three species are much rarer and strongly declining in the wild, this should be avoided. The Japanese pond turtle is an aquatic species found in many freshwater bodies of wate ...

Coenraad Jacob Temminck
Coenraad Jacob Temminck (; 31 March 1778 – 30 January 1858) was a Dutch aristocrat, zoologist and museum director. Biography Coenraad Jacob Temminck was born on 31 March 1778 in Amsterdam in the Dutch Republic. From his father, Jacob Temminck, who was treasurer of the Dutch East India Company with links to numerous travellers and collectors, he inherited a large collection of bird specimens. His father was a good friend of Francois Levaillant who also guided Coenraad. Temminck's ''Manuel d'ornithologie, ou Tableau systématique des oiseaux qui se trouvent en Europe'' (1815) was the standard work on European birds for many years. He was also the author of ''Histoire naturelle générale des Pigeons et des Gallinacées'' (1813–1817), ''Nouveau Recueil de Planches coloriées d'Oiseaux'' (1820–1839), and contributed to the mammalian sections of Philipp Franz von Siebold's ''Fauna japonica'' (1844–1850). Temminck was the first director of the National Museum of Natural ...

Threatened Species
Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of ''critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species * Endangered species * Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data ( data deficient) also are not conside ...

Endemic Reptiles Of Japan
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ...

Chinese Box Turtle
The Chinese box turtle (), also known as the yellow-margined box turtle, or golden-headed turtle, is a species of Asian box turtle. Taxonomically, it is called ''Cuora flavomarginata''. Anatomy ''C. flavomarginata'' has a highly domed shell, the carapace and plastron of which are a dark brown with a cream-yellow stripe on the vertebral keel. The edge of the plastron is lightly pigmented due to the marginal scutes' and plastral scutes' lighter pigmentation near their edges. The skin on the limbs is brown, while the top of the head is pale green. Each side of the head has a yellow line extending from behind the eye backward. The skin beneath the head and between the limbs is a lighter pinkish color. The name ''box turtle'' refers to ''C. flavomarginatas ability to bring the plastron to the edges of the carapace. This is enabled by a hinge on the plastron and ligaments connecting the carapace and plastron, which allows for limited movement. The forefeet have five claws, while the ...

Chinese Stripe-necked Turtle
The Chinese stripe-necked turtle (''Mauremys sinensis'') or golden thread turtle, is a species of turtle in the family Geoemydidae. 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 commo
