Amazon Basin Emerald Tree Boa

The Amazon Basin emerald tree boa has a yellow belly. The dorsum is dark green with an enamel-white vertebral stripe, which has confluent partial crossbars, often bordered by some black spots. C. batesii differs from C. caninus by the shape and the number of scales across the snout. C. batesii is bigger than C. caninus, growing to a total length (including tail) approaching 9 feet (2.7 m).

Corallus batesii, the "Amazon Basin species", as the common name suggests, is only found in the basin of the Amazon River, in southern Suriname, southern Venezuela to Colombia, Ecuador, Peru and Brazil and in the surrounding jungles of the Amazon River. It is found at elevations from sea level to 1,000 m (3,300 ft).

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).

English naturalist John Edward Gray originally described this species as Chrysenis batesii in 1860. The specific name, batesii, is in honor of Henry Walter Bates, an English naturalist and explorer, for whom Batesian mimicry is also named.
