Native to Round Island, a tiny island off the coast of Mauritius, the Round Island Burrowing Boa preferred to live on the topsoil layers of volcanic slopes.

Cause of extinction:The introduction of non-native species of rabbits and goats to the island destroyed vegetation and upset the boa’s habitat. The changing landscape did not suit its health.
