Dumarils are mainly terrestrial snakes. They are an adaptable species found in a wide variety of habitats, including humid rainforests, savannas, woodlands, and grasslands. They are most likely to be found near rivers and streams. They usually spend the daylight hours sheltering in mammal burrows, fallen logs, or debris piles.

Animal’s Behaviour

Like most snakes, Dumeril’s ground boas are mainly solitary. These snakes hibernate during the dry, cool months (May-July) which helps protect them from adverse weather conditions. Their cryptic coloration helps them hide from natural predators and man. There are few predators (other than man) in Madagascar that can provide a challenge to an adult specimen. Dumeril’s ground boas are ovoviviparous, Reproduction where the eggs develop within the maternal body without outside nourishment and hatch within the parent or immediately after laying. These snakes give live birth to 6-9 babies that have hatched inside the mother’s body after a gestation period of 4-8 months. The mother takes no care of the young. Several males will mate with one female. The babies are 16 inches to 19 inches at birth. Maturity occurs about 3 years of age.
