Ratsnake
Rat snakes are members – along with kingsnakes, milk snakes, vine snakes and indigo snakes – of the subfamily Colubrinae of the family Colubridae. They are medium to large constrictors and are found throughout much of the Northern Hemisphere. They feed primarily on rodents. Many species make attractive and docile pets and one, the corn snake, is one of the most popular reptile pets in the world. As with all snakes, they can be defensive when approached too closely, handled, or restrained. However, rat snake bites are not dangerous to humans. Like nearly all colubrids, rat snakes pose no threat to humans. Rat snakes were long believed to be completely nonvenomous, but recent studies have shown that some Old World species do possess small amounts of venom, though the amount is negligible relative to humans. Previously, most rat snakes were assigned to the genus ''Elaphe'', but many have been since renamed following mitochondrial DNA analysis performed in 2002. For th ...

Rhynchophis Boulengeri Head (edited)
The rhinoceros ratsnake (''Gonyosoma boulengeri''), also known commonly as the rhinoceros snake, rhino rat snake, and Vietnamese longnose snake, is a species of nonvenomous ratsnake in the family Colubridae. The species is found from northern Vietnam to southern China. It has a prominent, distinctive, scaled protrusion on the front of its snout, which has led to its common naming after a rhinoceros. Etymology The specific name, ''boulengeri'', is in honor of Belgian-British biologist George Albert Boulenger. Geographic range ''G. boulengeri'' is found in northern Vietnam including Tam Dao,''Rhynchophis boulengeri'' . www.schlangenland.de. Retrieved on 2013-01-03. and in southern .

Elaphe
''Elaphe'' is a genus of snakes in the family Colubridae. ''Elaphe'' is one of the main genera of the rat snakes, which are found in many regions of the northern hemisphere. ''Elaphe'' species are medium to large constrictors by nature. Although all of the species in ''Elaphe'' are nonvenomous, bites from rat snakes are still irritably painful and can potentially cause bacterial infections, especially due to the saliva."Rat snakes – lifecycle, predation, diet, bites, hibernation, pictures and videos." Ratsnake.org. (2010-09-23). Based on the analysis results, many species of ''Elaphe'' have been moved to the genera '' |

Coelognathus
''Coelognathus'' is a genus of seven rat snakes from South and Southeast Asia that were formerly assigned to the genus ''Elaphe''. Based on morphological evidence and protein similarities, in 2001, Helfenberger revalidated the name ''Coelognathus'' that had originally been proposed by Leopold Fitzinger in 1843. The distinction between ''Coelognathus'' and ''Elaphe'' was further supported by mitochondrial DNA sequence and additional morphological evidence in 2005. Species These species are recognized:"''Coelognathus'' ".

Elaphe Mandarina
The Mandarin rat snake (''Euprepiophis mandarinus'') is a species of nonvenomous colubrid snake endemic to Asia. It is closely related to '' Euprepiophis conspicillata'', the Japanese forest rat snake. Mandarin rat snakes are one of the most popular rat snakes found in the pet trade. Description It is a relatively small rat snake; adult size is no more than in total length (body + tail).

Coelognathus Helena
The common trinket snake (''Coelognathus helena'') is a nonvenomous constrictor species of colubrid snake native to south Central Asia. Etymology The specific name of this snake, ''helena'', is thought to be a reference to Helen of Troy, considered by many to be the epitome of female beauty and the most beautiful woman in the world.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Elaphe helena'', p. 120). Geographic range ''C. helena'' is found in Sri Lanka, southern India, Pakistan (Shangla), Nepal, and Bangladesh. Its type locality is "India: Vishakhapatnam" (Daudin, 1803). Description :''See snake scales'' for terms used.'' ''C. helena'' has the following scalation. The rostral is a little broader than deep, and visible from above. The suture between the internasals is much shorter than that between the prefrontals. The frontal is as long as its distance from the e ...

Squamata
Squamata (, Latin ''squamatus'', 'scaly, having scales') is the largest order of reptiles, comprising lizards, snakes, and amphisbaenians (worm lizards), which are collectively known as squamates or scaled reptiles. With over 10,900 species, it is also the second-largest order of extant (living) vertebrates, after the perciform fish. Members of the order are distinguished by their skins, which bear horny scales or shields, and must periodically engage in molting. They also possess movable quadrate bones, making possible movement of the upper jaw relative to the neurocranium. This is particularly visible in snakes, which are able to open their mouths very wide to accommodate comparatively large prey. Squamata is the most variably sized order of reptiles, ranging from the dwarf gecko (''Sphaerodactylus ariasae'') to the Reticulated python (''Malayopython reticulatus'') and the now-extinct mosasaurs, which reached lengths over . Among other reptiles, squamates are most close ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colubrinae
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 of th ...

Hermann Schlegel
Hermann Schlegel (10 June 1804 – 17 January 1884) was a German ornithologist, herpetologist and ichthyologist. Early life and education Schlegel was born at Altenburg, the son of a brassfounder. His father collected butterflies, which stimulated Schlegel's interest in natural history. The discovery, by chance, of a buzzard's nest led him to the study of birds, and a meeting with Christian Ludwig Brehm. Schlegel started to work for his father, but soon tired of it. He travelled to Vienna in 1824, where, at the university, he attended the lectures of Leopold Fitzinger and Johann Jacob Heckel. A letter of introduction from Brehm to gained him a position at the Naturhistorisches Museum. Ornithological career One year after his arrival, the director of this natural history museum, Carl Franz Anton Ritter von Schreibers, recommended him to Coenraad Jacob Temminck, director of the natural history museum of Leiden, who was seeking an assistant. At first Schlegel worked mainly o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Auguste Duméril
Auguste Henri André Duméril (30 November 1812 – 12 November 1870) was a French zoologist. His father, André Marie Constant Duméril (1774-1860), was also a zoologist. In 1869 he was elected as a member of the Académie des sciences. Duméril studied at the University of Paris, and in 1844 became an associate professor of comparative physiology at the university. From 1857, he was a professor of herpetology and ichthyology at the Muséum National d'Histoire Naturelle in Paris. In 1851, with his father, he published ''Catalogue méthodique de la collection des Reptiles''. With zoologist Marie Firmin Bocourt (1819–1904), he collaborated on a project called ''Mission scientifique au Mexique et dans l'Amérique Centrale'', a publication that was the result of Bocourt's scientific expedition to Mexico and Central America from 1864 to 1866. The section on reptiles is considered to be Dumeril's best written effort in the field of herpetology. Duméril died in 1870 during the sieg ...
