Furipteridae is one of the families of bats. This familiy contains only two species, the Smokey Bat and the Thumbless Bat. Both are from Central and South America, and are closely related to the bats in the Natalidae and Thyropteridae families. They can be recognized by their reduced and functionless thumbs, enclosed by the wing membranes, and their broad, funnel-shaped ears. There are only two genera in the group, each with a single species. They are insectivorous and can live in many different kinds of environments. They have greyish fur, and a small nose-leaf. Like many bats, they roost in caves.
