The body form is extremely slender with a long, pointed, projecting snout that is rather more than twice as long as the eye. Adult colouration varies from light brown to dull yellow-green and often a startling fluorescent green.[4] Adults may attain 1.8 m (6 feet) in total length, with a tail 0.6 m (2 feet) long.[5][6] Its appearance is very much like those of South American vine snakes. This is due to convergent evolution, as they are not closely related.
It is a rear-fanged species and is mildly venomous but is not considered a threat to humans.[2] It is diurnal, active during the day.[2]
