Round Island Burrowing Boa

Bolyeria multocarinata

Also known as Round Island Boa, Mauritian Burrowing Boa

Round Island burrowing boas were unique fossorial snakes possessing a divided maxilla, a specialized jointed upper jaw found only within splitjaw snakes. They spent their lives tunneling through loose topsoil and leaf litter beneath hardwood forests and palm savannas, ambushing native geckos and skinks. Severe soil erosion triggered by introduced rabbits and goats stripped away their burrowing habitat, driving the species to extinction during the 1970s.
