Acrantophis dumerili, commonly known as Dumeril's boa, is a species of non-venomous snake in the family Boidae. The species is endemic to Madagascar. No subspecies are currently recognized.
Adults of A. dumerili usually grow to 6.5 feet (2 m) in total length (including tail) with the maximum reported to be 8 foot, 6 inches (259 cm). Males usually have longer skinnier tails, while females tend to be larger overall.
A. dumerili is found on Madagascar. The type locality given in the original description is "Amérique mérid. ?", which is later given as "?" by Jan (1863).
Along the western coast and southwestern regions of Madagascar, it is found in a semi-arid habitat that gets fairly low amounts of precipitation.
The diet of A. dumerili consists of small animals, such as birds, lizards, and small mammals, including juvenile lemurs. It is also known to prey on other snakes.
Once exported from Madagascar in great numbers, trade in A. dumerili has since been heavily restricted. The species is, however, quite prolific in captivity, and captive bred individuals are easy to find in the exotic pet trade. Though its size makes it more suited to someone experienced with large constrictors, it has a typically docile nature, and readily feeds on rats. The main concern is that it is prone to stress, which can sometimes cause it to stop eating or can contribute to other health issues.
