The Amazon tree boa (Corallus hortulanus) is the most geographically widespread of the tree boas. It is found from northern South America throughout the Amazon Basin east of the Andes. Along with its wide distribution, it also varies widely in color and pattern. Natural color forms range from deep brown or black to bright yellow and red. Most individuals show some form of dorsal pattern, normally appearing as dark hourglass markings across the body. Occasionally uniform-colored snakes without any pattern are seen.
