Ahaetulla Pulverulenta
Brown-speckled whipsnake or brown vine snake (''Ahaetulla pulverulenta'') is a species of colubrid vine snake Endemism, endemic to Sri Lanka.

André Marie Constant Duméril
André Marie Constant Duméril (1 January 1774 – 14 August 1860) was a French zoologist. He was professor of anatomy at the National Museum of Natural History (France), Muséum national d'histoire naturelle from 1801 to 1812, when he became professor of herpetology and ichthyology. His son Auguste Duméril was also a zoologist, and the author citation (zoology), author citation Duméril is used for both André and his son. Life André Marie Constant Duméril was born on 1 January 1774 in Amiens and died on 14 August 1860 in Paris. He became a doctor at a young age, obtaining, at 19 years, the ''prévot'' of anatomy at the medical school of Rouen.

Paraphyletic
Paraphyly is a taxonomic term describing a grouping that consists of the grouping's last common ancestor and some but not all of its descendant lineages. The grouping is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic grouping (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of synapomorphies and symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term received currency during the debates of the 1960s and 1970s accompanying the rise of cladistics, having been coined by zoologist Willi Hennig to apply to well-known taxa like Reptilia (reptiles), which is paraphyletic with respect to birds. Reptilia contains the last common ancestor of reptiles and all descendants of that ancestor exc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
India
India, officially the Republic of India, is a country in South Asia. It is the List of countries and dependencies by area, seventh-largest country by area; the List of countries by population (United Nations), most populous country since 2023; and, since its independence in 1947, the world's most populous democracy. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is near Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia.

Chrysopelea
''Chrysopelea'' is a genus of snakes, commonly known as flying snakes or gliding snakes, that belong to the family Colubridae. ''Chrysopelea'' species are found in Southeast Asia, and are known for their ability to glide between trees. Flying snakes are mildly venomous, though the venom is dangerous only to their small prey. There are five species within the genus. Gliding ''Chrysopelea'' climbs using ridge scales along its underside, 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, and selects a desired landing area. Once it decides on a destination, it propels itself by thrusting its body up and away from the tree, sucking in its abdomen and flaring out its ribs to turn its body into a "pseudo concave wi ...

Dendrelaphis
''Dendrelaphis'' is a genus of snakes in the subfamily Ahaetuliinae of the family Colubridae. Species of the genus ''Dendrelaphis'' are distributed from Pakistan, India and southern China to Indonesia, Timor-Leste, the Philippines, Australia, New Guinea and the Solomon Islands. There are over 50 described species. Asian species are known commonly as bronzebacks, while the Australo-Papuan species are simply called tree snakes. All are non-venomous and entirely harmless to humans. Taxonomy ''Dendrelaphis'' is one of five genera belonging to the vine snake subfamily Ahaetuliinae, of which ''Dendrelaphis'' is most closely related to '' Chrysopelea'', as shown in the cladogram below: Species This list is based on the latest checklist of snakes in 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 synonymizing of ''D. solomonis'' within ''D. callig ...

Dryophiops
''Dryophiops'' is a genus of whip snakes of the family Colubridae, containing two species.. They are arboreal tree snakes, found in forests in Southeast Asia. Taxonomy The genus ''Dryophiops'' contains two species: the type species '' Dryophiops rubescens'' found in mainland Southeast Asia and Indonesia, and '' Dryophiops philippina'' found in the Philippines.

Proahaetulla Antiqua
''Proahaetulla'' is a monotypic genus of vine snake in the family Colubridae. It contains only one species, the keeled vine snake (''Proahaetulla antiqua''), which is endemic to the Western Ghats of India. Its natural habitat is montane rainforests of southern Western Ghats. Discovery The species was first discovered in 2011, when an individual was found in the Agasthyamalai Hills of Tamil Nadu and Kerala. It was initially thought to be a new species of ''Ahaetulla'', as it looked very similar to the species ''Ahaetulla dispar''. However, genetic analyses found it to be deeply divergent from any member in the genus ''Ahaetulla'', so it was classified in its own genus. Both the genus and species were ultimately described in 2019. Etymology The genus name ''Proahaetulla'' indicates the early divergence from ''Ahaetulla''. The species name ''antiqua'' is Latin for "antique" or "old", referencing the relatively old evolutionary divergence of the taxon. Taxonomy ''Proahaetulla'' ...

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 ...

Ahaetulla Anomala
The variable colored vine snake (''Ahaetulla anomala'') is a species of opisthoglyphous (rear-fanged venomous) colubrid vine snake found in Bangladesh and India. It is the first reported sexually dichromatic snake from the Indian Subcontinent, and until 2017 was formerly regarded as a subspecies of the green vine snake, ''Ahaetulla nasuta.'' Taxonomy This snake was first described by Thomas Nelson Annandale (the first director of the Zoological Survey of India) in 1906. It was later considered a subspecies of ''Ahaetulla nasuta'' in 1943. There has long been taxonomic confusion due to the sexually dimorphic coloring of species, with the green males resembling the long-nosed whip snake (''Ahaetulla nasuta''), while females are brown in color and physically resemble the brown-speckled whipsnake (''Ahaetulla pulverulenta''). To resolve this confusion, in 2017, a team of biologists conducted a molecular and morphological study of the snake, ultimately finding it to be a distinct spe ...
