The body form is extremely slender with a long, pointed, projecting snout which is rather more than twice as long as the eye. Adult coloration varies from light brown to dull yellow-green and often a startling fluorescent green.
Adults may attain 1.8 m [6 feet] in total length, with a tail 0.6 m [2 feet] long. 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.
The Asian vine snake feeds on small reptiles and amphibians, particularly lizards and tree frogs. In recent years, it has entered the pet trade and has become quite popular among hobbyists.
