Snout acuminate, projecting, without dermal appendage, rather more than twice as long as the eye. Internasals usually in contact with the labials; one to four small loreals between the prefrontal and the labials ; frontal as long as its distance from the end of the snout or a little longer, a little longer than the parietals; one preocular, in contact with the frontal; two postoculars; temporals 2+2 or 3+3, rarely 1+2; upper labials 9, fourth, fifth, and sixth entering the eye; 4 lower labials in contact with the anterior chin-shields, which are shorter than the posterior. Scales in 15 rows, usually faintly keeled on sacral region. Ventrals 203-234; anal divided; subcaudals 167-203, Bright green, pale olive, or grey-brown, with a yellow line along each side of the lower parts; interstitial skin of the neck black and white.[3]

Adults may attain 1.8 m (6 feet) in total length, with a tail .6 m (2 feet) long.[4]

Its appearance is very much like those of South American vine snakes. It is a rear-fanged species and is mildly venomous but is not considered a threat to humans.

Diet[edit]

The Asian vine snake feeds on small reptiles and amphibians, particularly lizards and tree frogs.

In captivity[edit]

In recent years, it has entered the pet trade and has become quite popular among hobbyists.

Subspecies[edit]

Four subspecies are recognized, including the nominate race.
