Nilssonia (turtle)
''Nilssonia'' is a genus of softshell turtles (family Trionychidae) from rivers, streams, ponds, and lakes in South Asia and Burma. In many treatments, it is monotypic, with the single species Burmese peacock softshell (''N. formosa''). However, the supposed other genus of peacock softshells, ''Aspideretes'', is more closely related to ''N. formosa'' than had been believed. They differ only in the neural plates between the first pleural scale pair of the bony carapace, which are fused into one in ''N. formosa'' and unfused in the others. (2007).

John Edward Gray
John Edward Gray, FRS (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoologica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Softshell Turtle
The Indian softshell turtle (''Nilssonia gangetica''), or Ganges softshell turtle is a species of softshell turtle found in South Asia in rivers such as the Ganges, Indus and Mahanadi. This vulnerable turtle reaches a carapace length of up to .Ernst, C.H.; Altenburg, R.G.M.; and Barbour, R.W. (1997). Aspideretes gangeticus'', Turtles of the World. Retrieved 17 June 2014. It feeds mostly on fish, amphibians, carrion and other animal matter, but also takes aquatic plants. This turtle is listed in part II of Schedule I of the Wild Life (Protection) Act, 1972 and possession of this species is an offence. Description The species is identified on the basis of the structure of the carapace and plastron. There are eight pairs of costal plates, the last well developed and in contact throughout on the median line; two neurals between the first pair of costals; plates coarsely pitted and vermiculate.

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 ...

John Anderson (zoologist)
John Anderson (4 October 1833 – 15 August 1900) was a Scottish anatomist and zoologist who worked in India as the curator of the Indian Museum, Calcutta. Early life Anderson was born in Edinburgh, the second son of Thomas Anderson, who worked in the National Bank of Scotland, and his wife Jane Cleghorn. He took an interest in natural history at an early age as did his brother Thomas Anderson, who worked at the Royal Botanic Garden in Calcutta from 1861 to 1863. He went to school at George Square Academy and Hill Street Institution before joining work at the Bank of Scotland. He left the bank to study medicine, and graduated from the University of Edinburgh in 1861. He studied anatomy under John Goodsir and received his MD in 1862 with a gold medal for his thesis in zoology. He was also associated with the founding of the Royal Physical Society which grew out of the Wernerian Society over which he presided. He was appointed to the chair of natural history in the Free C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nilssonia Nigricans
The black softshell turtle or Bostami turtle (''Nilssonia nigricans''), previously placed in genus ''Aspideretes'', is a species of freshwater turtle found in India (Assam and Tripura) and Bangladesh (Chittagong and Sylhet District, Sylhet). It was long believed to be inbred individuals of the Indian softshell turtle (''A. gangeticus'' or ''N. gangeticus'') or the Indian peacock softshell turtle (''A. hurum'' or ''N. hurum''), but while it is a close relative of the latter, it is a distinct species.Praschag ''et al.'' (2007) In the 1800s it was believed these turtles were brought from Iran to Chittagong shrine pond by Bayazid Bastami, Hazrat Bayezid Bostami. His turtles he had brought to this pond were treated as sacred and respected by the public. Previously declared Extinction, extinct by the International Union for Conservation of Nature in 2002, these turtles were found still to exist in a temple's pond called the Hayagriva Madhava Temple located in Assam, and in Kalyan Sagar ...

Georges Cuvier
Jean Léopold Nicolas Frédéric, Baron Cuvier (; 23 August 1769 – 13 May 1832), known as Georges Cuvier, was a French natural history, naturalist and zoology, zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phylum, phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastrophi ...
