Hognose
Hognose snake is a common name for several unrelated species of snake with upturned snouts, classified in 2 colubrid snake genera and 1 pseudoxyrhophiid snake genus. They include the following genera: *''Heterodon'', which occur mainly in the United States and northern Mexico *'' Leioheterodon'', the hognose snakes native to Madagascar *'' Lystrophis'', the South American hognose snakes. The North American ''Heterodon'' species are known for their habit of thanatosis: playing dead when threatened. Species Genus ''Heterodon'': *Mexican hognose snake, '' Heterodon kennerlyi'' ( Kennicott, 1860) *Gloyd's hognose snake, ''Heterodon nasicus gloydi'' ( Edgren, 1952) *Western hognose snake, ''Heterodon nasicus'' ( Baird & Girard, 1852) *Eastern hognose snake, ''Heterodon platirhinos'' ( Latreille, 1801) *Southern hognose snake, '' Heterodon simus'' (Linnaeus, 1766) Genus '' Leioheterodon'': *Speckled hognose snake, ''Leioheterodon geayi'' ( Mocquard, 1905) *Malagasy giant hogn ...

Coral Snakes
Coral snakes are a large group of elapid snakes that can be divided into two distinct groups, the Old World coral snakes and New World coral snakes. There are 16 species of Old World coral snakes, in three genera (''Calliophis'', '' Hemibungarus'', and ''Sinomicrurus''), and over 65 recognized species of New World coral snakes, in two genera (''Micruroides'' and ''Micrurus''). Genetic studies have found that the most basal lineages have origins in Asia, suggesting that the group originated in the Old World. While new world species of both genera are venomous, their bites are seldom lethal; only two confirmed fatalities have been documented in the past 100 years from the genus ''Micrurus''. Meanwhile, snakes of the genus ''Micruroides'' have never caused a medically-significant bite. North American coloration patterns Experts now recognize that certain coloration patterns and common mnemonics - such as the phrase “Red touch yellow, kill a fellow; red touch black, you’re good, ...

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 ...

Uruguay
Uruguay (; ), officially the Oriental Republic of Uruguay ( es, República Oriental del Uruguay), is a country in South America. It shares borders with Argentina to its west and southwest and Brazil to its north and northeast; while bordering the Río de la Plata to the south and the Atlantic Ocean to the southeast. It is part of the Southern Cone region of South America. Uruguay covers an area of approximately and has a population of an estimated 3.4 million, of whom around 2 million live in the metropolitan area of its capital and largest city, Montevideo. The area that became Uruguay was first inhabited by groups of hunter–gatherers 13,000 years ago. The predominant tribe at the moment of the arrival of Europeans was the Charrúa people, when the Portuguese first established Colónia do Sacramento in 1680; Uruguay was colonized by Europeans late relative to neighboring countries. The Spanish founded Montevideo as a military stronghold in the early 18th century bec ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.
