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]   |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. 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 ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Trionychidae
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, but t ...

William Patrick McCord
William is a male given name of Germanic origin.Hanks, Hardcastle and Hodges, ''Oxford Dictionary of First Names'', Oxford University Press, 2nd edition, , p. 276. It became very popular in the English language after the Norman conquest of England in 1066,All Things William"Meaning & Origin of the Name"/ref> and remained so throughout the Middle Ages and into the modern era. It is sometimes abbreviated "Wm." Shortened familiar versions in English include Will, Wills, Willy, Willie, Bill, and Billy. A common Irish form is Liam. Scottish diminutives include Wull, Willie or Wullie (as in Oor Wullie or the play ''Douglas''). Female forms are Willa, Willemina, Wilma and Wilhelmina. Etymology William is related to the given name ''Wilhelm'' (cf. Proto-Germanic ᚹᛁᛚᛃᚨᚺᛖᛚᛗᚨᛉ, ''*Wiljahelmaz'' > German ''Wilhelm'' and Old Norse ᚢᛁᛚᛋᛅᚼᛅᛚᛘᛅᛋ, ''Vilhjálmr'').

Peter Pritchard
Peter Charles Howard Pritchard (June 26, 1943 – February 25, 2020) was a leading turtle zoologist. Pritchard was educated at Oxford University and the University of Florida, where he received a Ph.D. and specialized in Zoology. He was most commonly known for his career of almost 40 years for the conservation of turtles. He worked with the World Wildlife Fund, spending four years there before joining Audubon Florida in 1973 as assistant executive director, senior vice president and acting president. In 1997, he founded a turtle conservation organization called the Chelonian Research Institute in Oviedo, Florida. Scott A. Thomson, curator of the Chelonian Research Institute notes that the CRI has 14500 tortoise and turtle specimens registered with some 2000 unregistered specimens. The collection comprises 100% of all turtle genera, 86% of all species and 72% of all subspecies - the third largest and most complete collection in the world. Pritchard also travelled to Guyana for h ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Chitra Indica
The Indian narrow-headed softshell turtle (''Chitra indica''), also known as the small-headed softshell turtle or the Indo-Gangetic softshell turtle, is an endangered species of softshell turtle native to waterways and rivers of the Indian subcontinent. It is very large (being one of the largest freshwater turtles), feeding on fish, frogs, worms, crustaceans and molluscs, and even the occasional swimming small rodent or other mammal. ''C. indica'', like other softshell turtles, uses it flexible (and somewhat leathery) shell to dig itself deep into sandy lake and river bottoms; here, it patiently waits (with just its nose, mouth and eyes exposed) for potential prey to swim by. They will also ambush and chase their prey, depending on availability, the time of year, and size of the prey.Das, I.; and Singh, S. (2009). Chitra indica.' Conservation Biology of Freshwater Turtles and Tortoises, Chelonian Research Monographs 5 In the past it was included as a subspecies of '' Chitra chitr ...

Nota Bene
(, or ; plural form ) is a Latin phrase meaning "note well". It is often abbreviated as NB, n.b., or with the ligature and first appeared in English writing . In Modern English, it is used, particularly in legal papers, to draw the attention of the reader to a certain (side) aspect or detail of the subject being addressed. While ''NB'' is also often used in academic writing, ''note'' is a common substitute. The markings used to draw readers' attention in medieval manuscripts are also called marks. The common medieval markings do not, however, include the abbreviation ''NB''. The usual medieval equivalents are anagrams from the four letters in the word , the abbreviation DM from ("worth remembering"), or a symbol of a little hand (☞), called a manicule or index, with the index finger pointing towards the beginning of the significant passage.Raymond Clemens and Timothy Graham, Introduction to Manuscript Studies (Ithaca: Cornell University Press, 2007), p. 44.

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
