Snake Scales
Snakes, like other reptiles, have skin covered in scales.Boulenger, George A. 1890 The Fauna of British India. p. 1 Snakes are entirely covered with scales or scutes of various shapes and sizes, known as snakeskin as a whole. A scale protects the body of the snake, aids it in locomotion, allows moisture to be retained within, alters the surface characteristics such as roughness to aid in camouflage, and in some cases even aids in prey capture (such as '' Acrochordus''). The simple or complex colouration patterns (which help in camouflage and anti-predator display) are a property of the underlying skin, but the folded nature of scaled skin allows bright skin to be concealed between scales then revealed in order to startle predators. Scales have been modified over time to serve other functions such as " eyelash" fringes, and protective covers for the eyes [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ahaetulla Head
''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 venom (poison), venomous and are what is commonly termed as 'rear-fanged' or more appropriately, opisthoglypha, 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 Viperidae, 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 convergent evolu ...

Natrix
''Natrix'' is a genus of Old World snakes found mainly across Eurasia (although the range of '' Natrix tessellata'' extends into Egypt and those of '' N. astreptophora'' and '' N. maura'' into north-west Africa) in the subfamily Natricinae of the family Colubridae. They are commonly called grass snakes and water snakes, but some other snake species also known commonly as "grass snakes" and "water snakes" are not in the genus. Species The genus ''Natrix'' contains five extant species and at least five extinct (fossil-only) species. ''Nota bene'': A binomial authority in parentheses indicates that the species was originally described in a genus other than ''Natrix''. Etymology ''Natrix'' is classical Latin for a water snake. The word comes from a Proto-Indo-European root meaning "snake", with cognates in the Celtic and Germanic languages, the latter including the English adder. It was probably influenced through folk etymology Folk etymology – also known as (generative) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphiesma Stolatum
The buff striped keelback (''Amphiesma stolatum'') is a species of nonvenomous colubrid snake found across Asia. It is a typically non-aggressive snake that feeds on frogs and toads. It belongs to the subfamily Natricinae, and is closely related to water snakes and grass snakes. It resembles an Asian version of the American garter snake. It is quite a common snake but is rarely seen. Anatomy and morphology A small, slender snake, the buff striped keelback is generally olive-brown to gray in colour. The head and the body are of the same colour. The body of the buff striped keelback is short, and it has a long slender tail which is almost a quarter of its length. Two yellow stripes along the length and to the sides of the spine are the distinctive feature of this snake. These stripes are diffuse at the head and are especially bright on the second half of its body. The keelback has irregular blackish crossbars on the body. Near the head the crossbars are prominent, whereas on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ahaetulla Nasuta
''Ahaetulla nasuta'', also known as Sri Lankan green vine snake and long-nosed whip snake, is a venomous, slender green tree snake endemic to Sri Lanka. It was previously known as the common green vine snake and was widely distributed across India and South East Asia, until a 2020 study split them into several different species, restricting ''Ahaetulla nasuta'' just to the Sri Lankan population. Etymology The genus name ''Ahaetulla'' comes from the Sri Lankan Sinhalese 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 João Ribeiro in 1685. The species name ''nasuta'' is Latin for "of the nose", in reference to its elongated snout.Reptile Database (2016). Ahaetulla nasuta.' Retrieved 16 May 2024. Vernacular names The Sinhala name "Aheatulla" or "eye-plucker" forms the taxonic genus name. In Tamil, it is known as pachai paambu. In Kan ...

Typhlopidae
The Typhlopidae are a family of blind snakes. They are found mostly in the tropical regions of Africa, Asia, the Americas, and all mainland Australia and various islands. The rostral scale overhangs the mouth to form a shovel-like burrowing structure. They live underground in burrows, and since they have no use for vision, their eyes are mostly vestigial. They have light-detecting black eye spots, and teeth occur in the upper jaw. Typhlopids do not have dislocatable lower jaw articulations restricting them to prey smaller than their oral aperture. All species in the family Typhlopidae are fossorial and feed on social fossorial invertebrates such as termites and ants. The tracheal lung is present and chambered in all species. One species, the Brahminy's blind snake, is the only unisexual snake, with the entire population being female and reproducing via parthenogenesis. The tail ends with a horn-like scale. Most of these species are oviparous. Currently, 18 genera are recognized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leptotyphlops Humilis - Head
''Leptotyphlops'' is a genus of nonvenomous blind snakes, commonly known as slender blind snakes and threadsnakes, in the family Leptotyphlopidae. The genus is endemic to and found throughout Africa. Eleven species have been moved to the genus '' Trilepida'', and other species have been moved to the genera '' Epacrophis'', ''Epictia'', '' Mitophis'', '' Myriopholis'', ''Namibiana'', '' Rena'', '' Siagonodon'', '' Tetracheilostoma'', and '' Tricheilostoma''. Description Most species of ''Leptotyphlops'' look much like shiny earthworms. They are generally black, grey, or blackish-brown and their scales give them a segmented appearance. Their common name comes from the fact that their eyes are greatly reduced almost to the point of uselessness, and hidden behind a protective head scale. The species which are called thread snakes are so named because of their very narrow, long bodies. Behavior All blind snakes including those of the genus ''Leptotyphlops'' are burrowing snakes, s ...

Viperidae
Vipers are snakes in the family Viperidae, found in most parts of the world, except for Antarctica, Australia, Hawaii, Madagascar, New Zealand, Ireland, and various other isolated islands. They are venomous snake, venomous and have long (relative to non-vipers), hinged fangs that permit deep envenomation of their prey. Three subfamilies are currently recognized. They are also known as viperids. The name "viper" is derived from the Latin word ''vipera'', -''ae'', also meaning viper, possibly from ''vivus'' ("living") and ''parere'' ("to beget"), referring to the trait viviparity (giving live birth) common in vipers like most of the species of Boidae. The earliest known vipers are believed to have diverged from the rest of the clade Caenophidia in the early Eocene. Description All viperids have a pair of relatively long Solenoglypha#Solenoglyph, solenoglyphous (hollow) fangs that are used to inject venom from glands located towards the rear of the upper jaws, just behind the ey ...

Pythonidae
The Pythonidae, commonly known as pythons, are a Family (biology), family of Venomous snake, nonvenomous snakes found in Africa, Asia, and Australia. Among its members are some of the largest snakes in the world. Ten Genus, genera and 39 species are currently recognized. Being naturally non-venomous, pythons must constrict their prey to induce cardiac arrest prior to consumption. Pythons will typically strike at and bite their prey of choice to gain hold of it; they then must use physical strength to constrict their prey, by coiling their muscular bodies around the animal, effectively suffocating it before swallowing whole. This is in stark contrast to venomous snakes such as the rattlesnake, for example, which delivers a swift, venomous bite but releases, waiting as the prey succumbs to envenomation before being consumed. Collectively, the pythons are well-documented and studied as constrictors, much like other non-venomous snakes, including the Boidae, boas and even kingsnakes ...
