Common Name and Ventral Coloration

Corallus batesii, commonly called the Amazon Basin emerald tree boa, has a yellow belly.

Dorsal Coloration and Spinal Stripe

Its back is dark green with an enamel-white stripe running along its spine. This stripe is connected to partial crossbars, which are often edged with small black spots.

Morphological Differences from Related Species

As its common name the Amazon Basin species suggests, this snake is found exclusively in the Amazon River basin, ranging from southern Suriname and southern Venezuela through Colombia, Ecuador, and Peru to Brazil, living in the jungles surrounding the Amazon River.

Elevation Range

It occurs at elevations between sea level and 1,000 meters, or 3,300 feet.

Reproductive Mode

Corallus batesii is ovoviviparous.
