The Madagascar Dumeril's boa is a large non-venomous snake that lives only on the island of Madagascar. It hunts at night on the ground and strangles prey with the rings of its body.
The Madagascar Dumeril's boa differs from tree boas by spending almost all its time on the ground. It is important for Madagascar's nature because it regulates the population of small animals and serves as prey for large predators.
