The Dumeril’s  ground boa’s black and brown coloring enables it to hide among the leaf litter on the forest floor.

Averaging 6–8 feet in length, Dumeril’s ground boas feature a rich reddish-brown coloration mixed with gray. Some individuals of Dumeril’s boa, exhibit large amounts of pink or copper coloration Their dorsal patterns are evenly shaped and outlined with black or brown, occasionally creating a zig-zag effect. It has the vertical pupils of a nocturnal animal. It can live up to 30 years in captivity.

These snakes find shelter in mammal burrows, fallen logs, piles of debris and other protected sites. This boa is a nocturnal hunter. It seems to prefer smaller animals like birds and lizards. They do not climb trees. Like other boas, it subdues its prey by constriction, which prevents the prey from breathing. Dumeril’s boa lacks the heat-sensitive facial pits present in many other boas, which are used to detect warm-blooded prey.
