John Edward Gray
John Edward Gray (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 zoological ... [...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 ...

Family (biology)
Family (, : ) 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". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

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] |
William Patrick McCord
William is a masculine given name of Germanic origin. It became popular in England after the Norman conquest 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 or Wil, Wills, Willy, Willie, Bill, Billie, and Billy. A common Irish form is Liam. Scottish diminutives include Wull, Willie or Wullie (as in Oor Wullie). Female forms include Willa, Willemina, Wilma and Wilhelmina. Etymology William is related to the German given name ''Wilhelm''. Both ultimately descend from Proto-Germanic ''*Wiljahelmaz'', with a direct cognate also in the Old Norse name ''Vilhjalmr'' and a West Germanic borrowing into Medieval Latin ''Willelmus''. The Proto-Germanic name is a compound of *''wiljô'' "will, wish, desire" and *''helmaz'' "helm, helmet".Hanks, Hardcastle and Hodges, ''Oxford Dictionary of First Names'', Oxford Un ...

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 chitra ...

Nota Bene
( ; plural: ) is the Latin language, Latin phrase meaning ''note well''. In manuscripts, ''nota bene'' is abbreviated in upper-case as NB and N.B., and in lower-case as n.b. and nb; the editorial usages of ''nota bene'' and ''notate bene'' first appeared in the English writing style, English style of writing around the year 1711. In Modern English, since the 14th century, the editorial usage of ''NB'' is common to the legal writing, legal style of writing of documents to direct the reader's attention to a thematically relevant aspect of the subject that qualifies the matter being litigated, whereas in academic writing, the editorial abbreviation ''n.b.'' is a casual synonym for ''footnote''. In medieval manuscripts, the editorial marks used to draw the reader's attention to a supporting text also are called marks; however, the catalogue of medieval editorial marks does not include the NB abbreviation. The medieval equivalents to the n.b.-mark are anagrams derived from the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called 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 (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". 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 ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
