Description

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.[2]

Adults may attain 1.8 m (6 feet) in total length, with a tail .6 m (2 feet) long.[3]

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

Ahaetulla prasina feeds on small reptiles and amphibians, particularly lizards and tree frogs.

In captivity

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