Acrantophis dumerili
Acrantophis dumerili, commonly known as Dumeril's boa, is a non-venomous boa species found on Madagascar. No subspecies are currently recognized. Etymology. The specific name, "dumerili", is in honor of French herpetologist André Marie Constant Duméril. Description. 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. The color pattern consists of a gray-brown ground color with darker patches, forming an effective camouflage against the  leaf litter of the forest floor of their native habitat. Distribution and habitat. "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. Conservation status. The species "A. dumerili" is classified as Least Concern (LC) on the IUCN Red List for the following criteria: A1cd (v2.3, 1994). This means that a population reduction of at least 20% has been observed, estimated , inferred or suspected over the last 10 years or three generations, whichever is the longer, based on a decline in area of occupancy, extent of occurrence and/or quality of habitat, and based on actual or potential levels of exploitation. The species was last assessed in 2011. "A. dumerili" is also listed as CITES Appendix I, which means that it is threatened with extinction and CITES prohibits international trade except when the purpose of the import is not commercial, for example for scientific research. It is threatened by deforestation and human persecution. In some areas it is feared and often killed  on sight. Although some native lore would relate stories of the souls of the tribes ancestors being in the snake skins, because patterns of faces on the sides of the snakes are interpreted, making them religiously sacred and therefore not dangerous to some cultures. Feeding. 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. Reproduction. In "A. dumerili" sexual maturity is reached within 3 to 5 years of age. Males have anal spurs, which are used in courtship. The mating season  is March through May, and the young are born some 6 to 8 months later. Ovoviviparous, females give birth to a litters of 6-28. Neonates are 12-18 inches (30–46 cm) long. Captivity. 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.
