Furipterus horrens, the thumbless bat, is misnamed – it clearly has a thumb, although the digit is reduced and is largely enclosed in the edge of the wing membrane. These tiny bats live in the Neotropics from Costa Rica south to Brazil. They fly like large moths through the forest understory, and roost in hollows in fallen trees and in small caves. Furipterus horrens is one of only two species in the Furipteridae.
