About Acrantophis dumerili Jan, 1860
Scientific name: Acrantophis dumerili Jan, 1860. Adults of this species usually reach a total length of 6.5 feet (2 m), including the tail. The maximum total length ever recorded is 8 feet 6 inches (259 cm). Males typically have longer, slimmer tails, while females grow to a larger overall size. Their color pattern has a gray-brown base color marked with darker patches, which provides effective camouflage against the leaf litter of their native forest floor habitat. This species is endemic to Madagascar. The type locality originally listed as "Amérique mérid. ?" was later marked simply as "?" by Jan in 1863. It occurs along the western coast and southwestern regions of Madagascar, where it inhabits a semi-arid environment with relatively low annual precipitation. Dumeril's ground boas live in semi-arid forest across western to southwestern Madagascar. Their specific habitat includes leaf litter, loose soil, and rocky terrain that supports their camouflage. When shelter is needed, these snakes use burrows dug by other animals. Individuals reach sexual maturity between 3 and 5 years of age. Males have anal spurs that they use during courtship. The mating season runs from March to May, and offspring are born 6 to 8 months after mating. Acrantophis dumerili is ovoviviparous; females give birth to litters of 6 to 28 live young. Newborn neonates measure 12 to 18 inches (30–46 cm) in length.
