Emerald tree boa

The Emerald tree boa (Corallus caninus) comes from South America. It spends its days hanging in the trees and vines of dense rain forests of Brazil, Suriname, French Guiana, Venezuela, Columbia, Guyana, Peru and Bolivia.
It is a night hunter and when it has captured its prey, it will hang up side down to swallow it.
The Emerald tree boa can reach about 6 feet in captivity and up to 9 feet in the Amazon basin.
Babies and juveniles start out a dark orange to brick red color, morphing into their beautiful shades of Emerald green in adulthood. These snakes have a row of white spots that are spaced apart, running the length of their back. Also, they have probably the longest front teeth of any non-venomous snake species.
They are from South America, and are not closely related to the Green tree Python (Morelia viridis) of New Guinea, Indonesia, and Cape York peninsula of Australia.
