Rafetus
''Rafetus'' is a genus of highly endangered softshell turtles in the family Trionychidae. It is a genus of large turtles which are found in freshwater habitats in Asia. Species According to most taxonomists, the genus ''Rafetus'' contains the following two species. *''Rafetus euphraticus'' – Euphrates softshell turtle *''Rafetus swinhoei'' – Yangtze giant softshell turtle A third species, ''Rafetus leloii'' ( synonym ''R. vietnamensis'' ), known commonly as the Hoan Kiem turtle, has been proposed as a species. It is considered a junior synonym of ''Rafetus swinhoei'' by most authorities, but some Vietnamese scientists insist the two forms are not identical. The last known individual at Hoan Kiem Lake was found dead on 19 January 2016. Taxonomy Cladogram As drawn by Walter G. Joyce, Ariel Revan, Tyler R. Lyson, and Igor G.

Yangtze Giant Softshell Turtle
The Yangtze giant softshell turtle (''Rafetus swinhoei''), also known as the Red River giant softshell turtle, the Shanghai softshell turtle, the speckled softshell turtle, and Swinhoe's softshell turtle, is an extremely rare species of turtle in the family Trionychidae. It may be the largest living freshwater turtle in the world. The species is endemic to eastern and southern China and northern Vietnam. Only two or three living individuals are known: one in China (captive) and one or two in Vietnam (wild). Following the deaths of a wild individual in Vietnam in January 2016 and a captive individual in China in 2019, the species is listed as critically endangered in the IUCN Red List. The female of the last breeding pair died at Suzhou Zoo in China in April 2019. A wild female was discovered in Vietnam on October 22, 2020, and another individual is believed to have been sighted in the same area.

Euphrates Softshell Turtle
The Euphrates softshell turtle (''Rafetus euphraticus''), also known as the Mesopotamian softshell turtle, is a species of softshell turtle in the family Trionychidae. It is found throughout much of the Euphrates–Tigris river basin in Iraq, Syria, Turkey and Khūzestān Province of Iran. Historically it has also been reported from Israel, but this likely involves confusion with the very similar '' Trionyx triunguis'' (the two typically require in-hand examination to be separated). The Euphrates softshell turtle is an endangered species that primarily is threatened by habitat loss and alteration, especially the building of dams, but to lesser extent also pollution and killing by fishermen. History The Euphrates softshell turtle became known to the western science when the French naturalist Guillaume-Antoine Olivier shot a specimen while crossing the Euphrates near Anah in June 1797. The local residents told him that the meat of this animal was not good to eat, but its fat w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hoan Kiem Turtle
The Hoàn Kiếm turtle, also ''Rafetus leloii'', was an obsolete or controversial taxon of turtle from Southeast Asia, based on specimens from Hoàn Kiếm Lake in Hanoi, Vietnam. Most experts classify this turtle as synonymous with the rare Yangtze giant softshell turtle (''Rafetus swinhoei''), although some Vietnamese biologists asserted that ''R. leloii'' is a distinct species.Farkas, B and Webb, R.G. 2003. ''Rafetus leloii Hà Dinh Dúc, 2000—an invalid species of softshell turtle from Hoan Kiem Lake, Hanoi, Vietnam (Reptilia, Testudines, Trionychidae).'' Zool. Abhandl. (Dresden), 53: 107-112. If the two taxa are to be considered distinct, ''R. leloii'' may be considered extinct. The last known turtle, affectionately known to locals as "Cụ Rùa", meaning “great grandfather turtle” in Vietnamese, was reported dead on 19 January 2016. A local man saw the body of the turtle floating in the water and reported it to the authorities. The last time the turtle was spotted ...

Softshell Turtle
The Trionychidae are a taxonomic family of a number of turtle genera, commonly known as softshell turtles. The family was erected by Leopold Fitzinger in 1826. Softshells include some of the world's largest freshwater turtles, though many can adapt to living in highly brackish areas. 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 They are called "softshell" because their carapaces lack horny scutes (scales), though the spiny softshell, '' Apalone spinifera'', does have some scale-like projections, hence its name. The carapace is leathery and pliable, particularly at the sides. The central part of the carapace has a layer of solid bone beneath it, as in other turtles, bu ...

Hutchemys
''Hutchemys'' is an extinct genus of softshell turtles from the late Cretaceous (Maastrichtian stage) to the late Paleocene of New Mexico, Montana, Wyoming, Utah, and North Dakota, United States.

François Marie Daudin
François Marie Daudin (; 29 August 1776 in Paris – 30 November 1803 in Paris) was a French zoologist. With legs paralyzed by childhood disease, he studied physics and natural history, but ended up being devoted to the latter. Daudin wrote ' (Complete and Elementary Treatise of Ornithology) in 1799–1800. It was one of the first modern handbooks of ornithology, combining Linnean binomial nomenclature with the anatomical and physiological descriptions of Buffon. While an excellent beginning, it was never completed. In 1800, he also published ''Recueil de mémoires et de notes sur des espèces inédites ou peu connues de mollusques, de vers et de zoophytes'' (Collection of memories and notes on new or little-known species of molluscs, worms and zoophytes). Daudin found his greatest success in herpetology. He published ''Histoire naturelle des reinettes, des grenouilles et des crapauds'' (Natural history of tree frogs, frogs and toads) in 1802, and ''Histoire naturelle, gé ...

Dresden
Dresden (, ; Upper Saxon: ''Dräsdn''; wen, label= Upper Sorbian, Drježdźany) is the capital city of the German state of Saxony and its second most populous city, after Leipzig. It is the 12th most populous city of Germany, the fourth largest by area (after Berlin, Hamburg and Cologne), and the third most populous city in the area of former East Germany, after Berlin and Leipzig. Dresden's urban area comprises the towns of Freital, Pirna, Radebeul, Meissen, Coswig, Radeberg and Heidenau and has around 790,000 inhabitants. The Dresden metropolitan area has approximately 1.34 million inhabitants. Dresden is the second largest city on the River Elbe after Hamburg. Most of the city's population lives in the Elbe Valley, but a large, albeit very sparsely populated area of the city east of the Elbe lies in the West Lusatian Hill Country and Uplands (the westernmost part of the Sudetes) and thus in Lusatia. Many boroughs west of the Elbe lie in the foreland of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
