Ahaetulla Isabellina
Wall's vine snake (''Ahaetulla isabellina'') is a species of tree snake endemic to the southern Western Ghats of India. Taxonomy It was formerly considered a subspecies of '' A. nasuta'', which is now considered to only be endemic to Sri Lanka. A 2020 study found ''A. nasuta'' to be a species complex of ''A. nasuta sensu stricto'' as well as '' A. borealis'', '' A. farnsworthi'', ''A. isabellina'', and '' A. malabarica'', elevating ''A. isabellina'' to species. The specific epithet is a reference to the isabelline yellow coloration of the species' dorsal body in live condition, which distinguishes it from other species in the complex. Geographic range This species is distributed in the southern Western Ghats in Tamil Nadu and Kerala south of the Palghat Gap, from the Anaimalai Hills The Anamala or Anaimalai, also known as the Elephant Mountains, are a range of mountains in the southern Western Ghats of central Kerala ( Idukki district, Ernakulam district, Pal ...

Snakes Of Asia
Snakes are elongated, limbless, carnivorous reptiles of the suborder Serpentes . Like all other squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads ( cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is not universal (see Amphisbaenia, Dib ...

Reptiles Of India
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates ( lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originate ...

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 ...

Sea Level
Mean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead the midpoint between a mean low and mean high tide at a particular location. Sea levels can be affected by many factors and are known to have varied greatly over geological time scales. Current sea level rise is mainly caused by human-induced climate change. When temperatures rise, mountain glaciers and the polar ice caps melt, increasing the amount of water in water bodies. Because most of human settlement and in ...

Tropical Evergreen Forests Of India
Tropical evergreen forests of India are found in the Andaman and Nicobar Islands, the Western Ghats, which fringe the Arabian Sea, the coastline of peninsular India, and the greater Assam region in the north-east. Small remnants of evergreen forest are found in Odisha state. Semi-evergreen forest is more extensive than the evergreen formation partly because evergreen forests tend to degrade to semi-evergreen with human interference. There are substantial differences between the three major evergreen forest regions.The average annual rainfall is 65-75 inches. The Western Ghats tropical wet evergreen forests are classified into low-, medium-, and high-elevation types. The Western Ghats monsoon forests occur both on the western (ghats) margins of the coastal and on the eastern side where there is less rainfall. These forests contain several tree species of great commercial significance (e.g. Indian rosewood ''(Dalbergia latifolia)'', Malabar Kino ''(Pterocarpus marsupium)'', teak '' ...

Anaimalai Hills
The Anamala or Anaimalai, also known as the Elephant Mountains, are a range of mountains in the southern Western Ghats of central Kerala ( Idukki district, Ernakulam district, Palakkad district, Thrissur district) and span the border of western Tamil Nadu (Coimbatore district and Tiruppur district) in Southern India. The name ''anamala'' is derived from the Malayalam word ''aana and'' the Tamil word ''aanai'', meaning elephant, or from tribal languages. ''Mala'' or ''Malai'' means 'hill', and thus 'Elephant hill'. Anamudi Peak (8,842 feet (2,695 metres)) lies at the southern end of the range and is the highest peak in southern India. The Palakkad Gap is the mountain pass which divides it from the Nilgiri Mountains. The northern slopes of the hills in Tamil Nadu now have coffee and tea plantations(especially around Valparai), as well as teak plantations of high economic value. The rest are mostly forests, of mainly two ecoregions-the South Western Ghats moist deciduous f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palakkad Gap
Palakkad Gap or Palghat Gap is a low mountain pass in the Western Ghats between Coimbatore in Tamil Nadu and Palakkad in Kerala. It has an average elevation of with a width of . The pass is located between the Nilgiri Hills to the north and Anaimalai Hills to the south. Origin and History There are various theories about the origin of Palakkad gap. One among them is that it is caused by the landslide due to rivers flowing in opposite directions. The Bharathappuzha river (River Ponnani) originates in the Palakkad Gap from rivulets and tributaries feeding from steep escarpment slopes along the flanks of the Ghats. Another theory suggests that the gap may be created by an asteroid strike around 800 million to 550 million years ago. Palakkad gap has played a major role in enabling human migration into Kerala from parts of Tamil Nadu. From 300 B.C. to 13th century, it also helped the Cheras rule the entire Kerala and the Kongu Nadu as one geographical unit from Karur in Wes ...
