This boa is endemic to Cuba, only living on this large Caribbean island. It is also the largest snake on the entire island. The cuban boa can measures up to 6 meters in length.
Its natural habitat is the tropical rainforest that used to cover a large part of Cuba, situated primarily on the easternmost end of the island.
Both ground and tree-dwellers, the cuban boa mainly feeds on small mammals, birds and lizards, which they kill by constriction. They frequent caves in some regions, specialists at capturing bats. They tend to hide among the undergrowth during the day, or in holes or under fallen trees, normally not far from water, and are active at dusk and night.
The cuban boa is in serious danger of extinction mainly because of the destruction of its habitat.
