Corallus batesii, also known commonly as the Amazon Basin emerald tree boa, is a species of snake in the subfamily Boinae of the family Boidae.

[3][4] English naturalist John Edward Gray originally described this species as Chrysenis batesii in 1860.

The dorsum is dark green with an enamel-white vertebral stripe, which has confluent partial crossbars, often bordered by some black spots.

C. batesii is bigger than C. caninus, growing to a total length (including tail) approaching 9 feet (2.7 m).

[1] Corallus batesii is capable of hunting small airborne prey, such as bats and birds, as well as rodents, opossums, lizards (including Thecadactylus solimoensis), and other snakes (including Bothrops atrox).
