Madagascar Ground Boa
Acrantophis madagascariensis · also called malagasy ground boa
Coiled low in leaf litter rather than high in the branches, a Madagascar ground boa waits with the patience of a true ambush predator, one of the heaviest and largest snakes found anywhere on the island.
Overview
The Madagascar ground boa, Acrantophis madagascariensis, is a Vulnerable snake endemic to forest habitat across northern, western, and eastern Madagascar. Its heavy build, ground-dwelling ambush lifestyle, and status as one of the island’s largest snakes set it apart from its more slender, arboreal relative, the Madagascar tree boa.
A heavyweight of the forest floor
Where the Madagascar tree boa makes its living in the branches, the ground boa takes the opposite approach, relying on its size and strength to subdue prey encountered on the forest floor rather than lying in wait above.
Status
Vulnerable, with a declining population threatened by deforestation and collection for the exotic pet trade, though still present across parts of its native range.
Madagascar Ground Boa: common questions
How does the Madagascar ground boa differ from the Madagascar tree boa?
The ground boa is heavier-bodied and hunts primarily on the forest floor, while the tree boa is more slender and spends nearly all its time coiled in branches; both are large constrictors native only to Madagascar.
How big does the Madagascar ground boa get?
It is one of the largest snakes found anywhere in Madagascar, with a notably heavy, muscular body suited to subduing sizeable prey.
Does the Madagascar ground boa lay eggs?
No, like other boas it gives birth to live young rather than laying eggs.
Why is the Madagascar ground boa vulnerable?
Deforestation across its range and collection for the exotic pet trade have driven a continuing population decline, though it remains present across parts of northern, western, and eastern Madagascar.
