Boa of Duméril

Acrantophis dumerili

Common name

Boa of Duméril

Habitat

The Duméril Boa lives in dry forests but is not restricted to intact habitats. Populations have been found in highly degraded habitats such as eucalyptus forests or villages, always found from sea level to 1.300m altitude. They are also found in the savanna located in the central highlands of the island.

Biology and behavior

Like most members of the Boidae family, it is a fairly robust snake that can reach 1,8 meters in length. It has gray and brown bands with black markings that run throughout its body.

It is generally terrestrial, solitary and, like most boas, it is ovoviviparous so the eggs hatch inside the mother's body and are born as completely independent offspring.

Although younger individuals are mainly nocturnal, in the case of adults, there is no pattern of daytime or nighttime activity. It normally hunts at night as it takes advantage of the drop in temperatures to detect the heat emitted by its prey, through heat-sensitive holes around its mouth. It feeds on small mammals that it kills by curling its body around it and suffocating them in its rings.

Threats facing this species include the widespread destruction of habitat that has occurred in Madagascar for agriculture or livestock grazing. In some areas, snakes are captured for food and the skins are used for the leather trade, or they are considered an omen of bad luck as they are predators of domestic birds.

Some
curiosities

Probably due to the low presence of large predators on the island of Madagascar, Duméril's Boas have smaller litters than other boa constrictors, allowing the offspring to be larger at birth. In this way, they avoid being eaten by smaller predators.
