Colubrine
The Colubrinae are a subfamily of the family Colubridae of snakes. It includes numerous genera, and although taxonomic sources often disagree on the exact number, The Reptile Database lists 717 species in 92 genera as of September 2019. It is the second largest subfamily of colubrids, after Dipsadinae. Many of the most commonly known snakes are members of this subfamily, including rat snakes, king snakes, milk snakes, vine snakes, and indigo snakes. Colubrine snakes are distributed worldwide, with the highest diversity in North America, Asia, northern Africa, and the Middle East. There are relatively few species of colubrine snakes in Europe, South America, Australia, and southern Africa, and none in Madagascar, the Caribbean, or the Pacific Islands. Colubrine snakes are extremely morphologically and ecologically diverse. Many are terrestrial, and there are specialized fossorial (e.g. ''Tantilla'') and arboreal (e.g. '' Oxybelis'') groups, but no truly aquatic groups. Some ...

Zamenis Situla
The European ratsnake or leopard snake (''Zamenis situla''), is a species of nonvenomous colubrid snake endemic to Europe, Asia Minor, and the Caucasus. Geographic range ''Z. situla'' is found in Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Italy, North Macedonia, Malta, Montenegro, Turkey, Ukraine, and possibly Cyprus. Description The leopard snake is gray or tan with a dorsal series of reddish or brown transverse blotches, which have black borders. On each side is a series of smaller black spots, alternating with the dorsal blotches. There is a Y-shaped dark marking on the occiput and nape, a crescent-shaped black band from eye to eye across the prefrontals, and a black band from the postoculars diagonally to the corner of the mouth.

Sonora Semiannulata Semiannulata, Ozark County, Missouri, By Peter Paplanus
Sonora (), officially Estado Libre y Soberano de Sonora ( en, Free and Sovereign State of Sonora), is one of the 31 states which, along with Mexico City, comprise the Federal Entities of Mexico. The state is divided into 72 municipalities; the capital (and largest) city of which being Hermosillo, located in the center of the state. Other large cities include Ciudad Obregón, Nogales (on the Mexico-United States border), San Luis Río Colorado, and Navojoa. Sonora is bordered by the states of Chihuahua to the east, Baja California to the northwest and Sinaloa to the south. To the north, it shares the U.S.–Mexico border primarily with the state of Arizona with a small length with New Mexico, and on the west has a significant share of the coastline of the Gulf of California. Sonora's natural geography is divided into three parts: the Sierra Madre Occidental in the east of the state; plains and rolling hills in the center; and the coast on the Gulf of California. It is pri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dendrelaphis
''Dendrelaphis'' is a genus of colubrid snakes, distributed from Pakistan, India and southern China to Indonesia, Timor-Leste, the Philippines, Australia, New Guinea and the Solomon Islands. There are over forty described species. Asian species are known commonly as bronzebacks, while the Australo-Papuan species are simply called treesnakes. All are non-venomous and entirely harmless to humans. Classification This list is based on the latest checklist of the snakes of the world and recent revisions and descriptions published in the scientific literature. The authors of a 2015 revision of the Australo-Papuan ''Dendrelaphis'' species recommended the synonymy of ''D. solomonis'' within ''D. calligaster'', the elevation of ''D. keiensis'' to species status, the resurrection of ''D. lineolatus'' from within ''D. calligaster'', and the resurrection of ''D. macrops'' and elevation of ''D. striolatus'' from within ''D. punctulatus''. They also confined ''D. punctulatus'' to Australi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysopelea
''Chrysopelea'', more commonly known as the flying snake or gliding snake is a genus that belongs to the family Colubridae. Flying snakes are mildly venomous, though the venom is dangerous only to their small prey. Their range is in Southeast Asia (the mainland (Vietnam, Cambodia, Myanmar, and Laos), Greater and Lesser Sundas, Maluku, and the Philippines), southernmost China, India, and Sri Lanka.De Rooij, N. (1915).The reptiles of the Indo-Australian archipelago Leiden: E.J. Brill. Accessed 2009-07-14. Gliding ''Chrysopelea'' is also known by its common name "flying snake". It climbs using ridge scales along its belly, pushing against the rough bark of tree trunks, allowing it to move vertically up a tree. Upon reaching the end of a branch, the snake continues moving until its tail dangles from the end of the branch. It then makes a J-shape bend, leans forward to select the level of inclination it wishes to use to control its glide path, as well as selecting a desired landi ...

Ahaetulla
''Ahaetulla,'' commonly referred to as Asian vine snakes or Asian whip snakes, is a genus of colubrid snakes distributed throughout tropical Asia. They are considered by some scientists to be mildly venomous and are what is commonly termed as 'rear-fanged' or more appropriately, opisthoglyphous, meaning their enlarged teeth or fangs, intended to aid in venom delivery, are located in the back of the upper jaw, instead of in the front as they are in vipers or cobras. As colubrids, Ahaetulla do not possess a true venom gland or a sophisticated venom delivery system. The Duvernoy's gland of this genus, homologous to the venom gland of true venomous snakes, produces a secretion which, though not well studied, is considered not to be medically significant to humans. Green-colored members of this genus are often referred to as green vine snakes. They are not to be confused with the "green vine snake" '' Oxybelis fulgidus'', which convergently appears very similar but is found in Cen ...

Ahaetullinae
The Ahaetuliinae are a subfamily of the snake family Colubridae that was erected in 2016 and comprises five genera containing 63 species (''Ahaetulla'' 7 species '' Chrysopelea'' species ''Dendrelaphis'' 5 species ''Dryophiops'' speciesand '' Proahaetulla'' species that are more closely related to one another than to members of the subfamily Colubrinae. Previously placed within Colubrinae, Ahaetuliinae was strongly supported as the sister group to Colubrinae in a 2016 study by Figueroa et al. Ahaetuliine snakes are arboreal and have keeled ventral and subcaudal scales (laterally notched in some species), and enlarged posterior grooved fangs (lacking in some ''Dendrelaphis''). The name comes from the genus ''Ahaetulla'', which gets its name from the Sri Lankan Sinhalese language words ''ahaetulla/ahata gulla/as gulla'', meaning “eye plucker” or “eye picker”, because of the belief that they pluck out the eyes of humans, as first reported by the Portuguese traveler Jo ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his Nobility#Ennoblement, ennoblement in 1761 as Carl von Linné#Blunt, Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In ...

Colubroidea
Colubroidea is a superfamily of snakes in the clade Colubroides that includes Colubridae, with some studies splitting Colubridae into multiple families that make up Colubroidea. Historically, Colubroidea also included other caenophidian snakes such as cobras and vipers, as these snakes form a clade. However these groups are now divided into several distinct, but related, families. Zaher et al. (2009) proposed to redefine Colubroidea for colubrids and related families, while designating Colubroides as the group containing vipers and cobras as well as colubroids. The ReptileDatabase considers Colubroidea to be composed of Colubridae and the members of its sister group, Elapoidea, and does not recognize the division of Colubridae into multiple families. Classification Phylogeny Families and Subfamilies Usual taxonomy: * Family: Colubridae Oppel, 1811 ** Subfamily: Grayiinae Günther, 1858 ** Subfamily: Calamariinae Bonaparte, 1838 ** Subfamily: Ahaetullinae Figueroa, ...

Lampropeltini
Lampropeltini is a tribe of colubrid snake endemic to New World. These include the kingsnakes, milk snake, corn snake, gopher snakes, pine snakes, and bullsnakes. At least 51 species have been recognized and the group have been heavily studied for biogeography, morphology, ecology, and phylogenetics. The internal relationships among the genera has been disputed, but generally the most supported placement of the genera are as follows: * The basal placement of ''Senticolis'' * The sister relationship between '' Pantherophis'' and ''Pituophis'', with at least one study in 2016 suggesting the former genus is paraphyletic in respect to the latter * The sister relationship between '' Cemophora'' and '' Lampropeltis'' * A clade consisting of genera of '' Rhinocheilus'', ''Pseudelaphe'', and ''Arizona'' Pyron and Burbink (2009) phylogeny of the tribe using 31 species using 7 loci (1 nDNA and 6 mtDNA), as well as incorporating the fossil record: Lampropeltini section from Pryon et al. ...
