Ahaetulla nasuta

The green vine snake (Ahaetulla nasuta) ඇහැ‍ටුල්ලා (ahaetulla) in Sinhala, is a slender green tree snake found in India, Sri Lanka, Bangladesh, Burma, Thailand, Cambodia and Vietnam. Not to be confused with Oxybelis fulgidus, "green vine snake" found in Central and South America.

Description[edit]

Feeding on Rana temporalis

The green vine snake is diurnal and mildly venomous. The reptile normally feeds on frogs and lizards using its binocular vision to hunt. They are slow moving, relying on camouflaging as a vine in foliage. The snake expands its body when disturbed to show a black and white scale marking. Also, they may open their mouth in threat display and point their head in the direction of the perceived threat. There is a widespread myth in parts of southern India that the species uses its pointed head to blind its human victims.

The species is viviparous, giving birth to young that grow within the body of the mother, enclosed within the egg membrane. They may be capable of delayed fertilization (parthenogenesis is rare but not unknown in snakes) as a female in the London zoo kept in isolation from August, 1885 gave birth in August, 1888.[1] The venom is mild and causes swelling. Symptoms will subside within three days.[2]

Taxonomic description[edit]

The following description with diagnostic characters is from Boulenger (1890):[3]

Snout pointed, terminating in a dermal appendage, which is shorter than the eye and formed entirely by the rostral; the length of the snout, without the appendage, about twice the diameter of the eye or rather more. No loreal; internasals and prefrontals in contact with the labials; frontal as long as its distance from the rostral or a little longer, as long as the parietals or a little longer; two preoculars and a small subocular (or one preocular and two suboculars), upper preocular in contact with the frontal; two postoculars; temporals 1+2 or 2+2; upper labials 8, fifth entering the eye; 4 lower labials in contact with the anterior chin-shields, which are shorter than the posterior. Scales in 15 rows. Ventrals 172-188; anal divided; subcaudals 140-166. Bright green or pale brownish, the interstitial skin between the scales black and white on the anterior part of the body, which appears striped when distended; a yellow line along each side of the lower surface. Total length 5 feet: tail 2.
