Dendrelaphis Punctulatus
''Dendrelaphis punctulatus'', also known commonly as the Australian tree snake, the common tree snake, and the green tree snake, is a species of slender, large-eyed, diurnal, non-venomous snake in the family Colubridae. The species is native to many parts of Australia, especially in the northern and eastern coastal areas, and to Papua New Guinea. It is readily recognised as it is an agile snake with a very slender body and tail. The dorsal body colour varies from golden yellow, to bright green, to olive-green, to black, sometimes even blue. It is frequently pale yellow on the throat and belly, but other pale colours have been noted. Blue flecks are present on the flanks. The eyes are large, with typically golden-coloured irises and large round pupils. It is found in a variety of habitats ranging from rainforest to woodland to urban areas where it preys on fish, frogs, and other small animals. It is a non-venomous species and does not constrict its prey, but rather relies on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Proahaetulla
''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 ''Proahaetul ...

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 Cent ...

Cladogram
A cladogram (from Greek language, Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an Phylogenetic tree, evolutionary tree because it does not show how ancestors are related to descendants, nor does it show how much they have changed, so many differing evolutionary trees can be consistent with the same cladogram. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. There are many shapes of cladograms but they all have lines that branch off from other lines. The lines can be traced back to where they branch off. These branching off points represent a hypothetical ancestor (not an actual entity) which can be inferred to exhibit the traits shared among the terminal taxa above it. This hypothetical ancestor might then provide clues about the order of evolution of various features, adaptation, and other e ...

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 ...
