Dumeril's ground boa

Latin Name
Acrantophis dumerili




Averaging 6–8 feet in length, Dumeril's ground boas feature a rich reddish-brown coloration mixed with gray. Their dorsal patterns are evenly shaped and outlined with black or brown, occasionally creating a zig-zag effect.



Madagascar and the Mascarene Islands.


The species is vulnerable due to habitat loss.


Sparse, open woodland.


Mainly terrestrial; these snakes feed mainly on mammals and birds.

Life History

These snakes find shelter in mammal burrows, fallen logs, piles of debris and other protected sites. They hibernate during the dry, cool months, normally May–July. The snakes mate shortly after emerging from hibernation. After a 6–8 month gestation period, small litters of 2–21 young are born live. At birth the young are 19–24 inches long.

Special Adaptations

Cryptic coloration helps the snake remain inconspicuous.
