The northern Western Ghats vine snake (Ahaetulla borealis) is a species of tree snake endemic to the northern Western Ghats of India. [1] [2] [3]

Contents

Taxonomy

It was formerly considered conspecific with 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 . [1]

Geographic range

This species is one of the most widespread of Western Ghats Ahaetulla, ranging from Sirsi, Karnataka north to Matheran, Maharashtra. Near the southern edge of its range it is flanked by A. farnsworthi, from which it is likely separated by the Sharavathi River basin. [1]

Habitat

It is found in low-to-mid-elevation moist deciduous and semi-evergreen forests at a mean sea leve l of 300 – 750. [1]

The Western Ghats, also known as the Sahyadri mountain range, is a mountain range that covers an area of 160,000 km2 (62,000 sq mi) in a stretch of 1,600 km (990 mi) parallel to the western coast of the Indian peninsula, traversing the states of Gujarat, Maharashtra, Goa, Karnataka, Kerala and Tamil Nadu. It is a UNESCO World Heritage Site and one of the 36 biodiversity hotspots in the world. It is sometimes called the Great Escarpment of India. It contains a very large proportion of the country's flora and fauna, many of which are endemic to this region. The Western Ghats are older than the Himalayas. They influence Indian monsoon weather patterns by intercepting the rain-laden monsoon winds that sweep in from the south-west during late summer. The range runs north to south along the western edge of the Deccan Plateau and separates the plateau from a narrow coastal plain called the Western Coastal Plains along the Arabian Sea. A total of 39 areas in the Western Ghats, including national parks, wildlife sanctuaries and reserve forests, were designated as world heritage sites in 2012 – twenty of them in Kerala, ten in Karnataka, six in Tamil Nadu and four in Maharashtra.

The Eastern Ghats are a discontinuous range of mountains along India's eastern coast. The Eastern Ghats pass through the states of Odisha and Andhra Pradesh to Tamil Nadu by, passing parts of Karnataka and Telangana on the way. They are eroded and cut through by four major rivers of peninsular India, the Mahanadi, Godavari, Krishna and Kaveri. Sitamma Konda is the highest point in both Andhra Pradesh and the Eastern Ghats at 1,680 metres (5,510 ft). The Biligiriranga Hills in Karnataka are the tallest hill range in the Eastern Ghats, with many peaks above 1500 m in height.

<i>Ahaetulla</i> Genus of snakes

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.

<span class="mw-page-title-main">Caecilians of the Western Ghats</span>

The Western Ghats in India are home to several species of caecilians (Gymnophiona). Caecilians are legless, burrowing amphibians which mostly live in leaf litter, loose soil, under rocks and decaying logs. They are also found in agricultural fields and only surface during the monsoon. The body is elongated and smooth with a slimy skin. The smaller caecilians superficially resemble earthworms while the larger ones are often mistaken for snakes. However, they can be told apart from earthworms by the presence of eyes, teeth and skeleton and from snakes by the lack of scales on skin. The eyes in caecilians are not well developed which is most likely to be because of their burrowing life style. They are considered as rare which is apparently due to their subterranean habits. To see them one has to search carefully and be at the right place and at the right time. There are few places where they are common, but, at least one species was reported to be abundant in agricultural fields in Kerala. The larger caecilians can resemble snakes, but their skin is smooth, not scaly.
