Mixcoatlus
''Mixcoatlus'' is a small genus of pit vipers endemic to Mexico. The genus was created in 2011. The name ''Mixcoatlus'' is derived from the Náhuatl, Nahuatl word ''Mixcoatl'' or "cloud serpent", a deity of the Aztecs, Aztec and several other Mesoamerican civilizations. This name also refers to the geographic restriction of this clade to elevations above 2,000 meters. Species There are three species: *''Mixcoatlus barbouri'' (Dunn, 1919) *''Mixcoatlus browni'' (Shreve, 1938) *''Mixcoatlus melanurus'' (Müller, 1923) References Crotalinae Snakes of North America Endemic reptiles of Mexico Snake genera {{snake-stub ...

Mixcoatlus Browni
''Mixcoatlus browni'' (commonly known as Brown's montane pit viper, sometimes Mexican montane pitviper) is a species of pit viper found at high elevations in Guerrero, Mexico. This species was previously placed in the genus '' Agkistrodon'', where it was considered to be a junior synonym of '' Cerrophidion barbouri''. Molecular evidence has since demonstrated that ''M. browni'' is a distinct species and the genus name was subsequently changed. The genus ''Mixcoatlus'' is derived from the Nahuatl word '' Mixcoatl'' or "cloud serpent", a deity of the Aztec and several other Mesoamerica civilizations. This name also refers to the geographic restriction of this clade to elevations above . Description Not much is known about this species. This species is diurnal and it is usually found basking or moving throughout the day. This species has been seen by researchers to have more of a prehensile tail than other species in this genus. There is currently no evidence to suggest that ''M. b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mixcoatl
Mixcoatl ( nah, Mixcōhuātl}, from mixtli "cloud" and cōātl "serpent"), or Camaxtle or Camaxtli, was the god of the hunt and identified with the Milky Way, the stars, and the heavens in several Mesoamerican cultures. He was the patron deity of the Otomi, the Chichimecs, and several groups that claimed descent from the Chichimecs. Under the name of Camaxtli, Mixcoatl was worshipped as the central deity of Huejotzingo and Tlaxcala. Representation Mixcoatl is represented with a black mask over his eyes and distinctive red and white pin stripes painted on his body. These features are shared with Tlahuizcalpanteuctli, the Lord of the Dawn, god of the morning star, as well as Itzpapalotl, goddess of infant mortality who was sometimes said to be his mother. Unlike Tlahuizcalpanteuctli, Mixcoatl can usually be distinguished by his hunting gear, which included a bow and arrows, and a net or basket for carrying dead game.

Pit Viper
The Crotalinae, commonly known as pit vipers,Mehrtens JM (1987). ''Living Snakes of the World in Color''. New York: Sterling Publishers. 480 pp. . crotaline snakes (from grc, κρόταλον ''krotalon'' castanet), or pit adders, are a subfamily of vipers found in Eurasia and the Americas. Like all other vipers, they are venomous. They are distinguished by the presence of a heat-sensing pit organ located between the eye and the nostril on both sides of the head. Currently, 23 genera and 155 species are recognized: These are also the only viperids found in the Americas. The groups of snakes represented here include rattlesnakes, lanceheads, and Asian pit vipers. The type genus for this subfamily is '' Crotalus'', of which the type species is the timber rattlesnake, ''C. horridus''. These snakes range in size from the diminutive hump-nosed viper, '' Hypnale hypnale'', that grows to a typical total length (including tail) of only , to the bushmaster, '' Lachesis muta'' ...

Benjamin Shreve
Benjamin Shreve (1908–1985) was an American amateur herpetologist. He was from a wealthy Boston family of jewellers (partners and managers of Shreve, Crump & Low) and worked at the Harvard Museum of Comparative Zoology as a volunteer. He was trained by Arthur Loveridge to deal with materials from elsewhere than Africa. Shreve described many species from the West Indies together with Thomas Barbour. In these papers, Shreve is said to have done the "spadework" while Barbour wrote "florid" introductions. Species named in honor of Benjamin Shreve Reptiles named in honor of Shreve include: *''Dipsadoboa shrevei'' – Shreve's (nocturnal) tree snake *''Oreosaurus shrevei'' – Shreve's lightbulb lizard (''Riama shrevei'' is a synonym) *''Anolis shrevei'' – Shreve's anole *''Sphaerodactylus shrevei'' – Shreve's least gecko Amphibians named in honor of Shreve are: *''Dendrobates shrevei'' (now a synonym of '' Andinobates minutus'') – bluebelly poison frog *''Hyla shrevei'' ...

Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aztecs
The Aztecs () were a Mesoamerican culture that flourished in central Mexico in the post-classic period from 1300 to 1521. The Aztec people included different ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl language and who dominated large parts of Mesoamerica from the 14th to the 16th centuries. Aztec culture was organized into city-states ('' altepetl''), some of which joined to form alliances, political confederations, or empires. The Aztec Empire was a confederation of three city-states established in 1427: Tenochtitlan, city-state of the Mexica or Tenochca; Texcoco; and Tlacopan, previously part of the Tepanec empire, whose dominant power was Azcapotzalco. Although the term Aztecs is often narrowly restricted to the Mexica of Tenochtitlan, it is also broadly used to refer to Nahua polities or peoples of central Mexico in the prehispanic era, as well as the Spanish colonial era (1521–1821).
