The Red-tailed green ratsnake is a non-venomous robust powerful snake, with wide smooth scales on its belly that are ideal for climbing trees and across branches. It has smaller, smooth scales on its back, which are usually bright green or light green and may have a black net-like pattern. As some of its common names indicate, this snake has a green body with a red tail but is usually brown. It also has a dark line horizontally across the eye. On the sides of its black tongue, there may be a brown and blue color. The top of the head may be dark green, yellow-green, or yellow in color. There is also a gray-colored morph with a yellow head that exists in Panay, in the Philippines.

Distribution
