It gets its name from the unusual appearance of its face, which is due to the flaps of skin that hang from it, its poorly developed nose,[2] and "large, round ears that join across their forehead".

Records of these bats then resume along the Caribbean coast of South America in countries such as Colombia, Venezuela, and Trinidad and Tobago.

Fossils have also been found in many of the Caribbean islands such as Cuba, Jamaica, Hispaniola, Bahamas, Trinidad and Tobago, and Aruba.

When they leave their roosting spot (usually a cave, mine shaft, or tunnel) at night they fly in dense, fast-moving groups until they get to their feeding grounds where they disperse.

These bats only seem to carry one embryo at a time and are thought to give birth in the spring between March and June.

[2] Because pregnant females are so sensitive to changes in temperature, they appear to roost deeper in the caves than the rest of the colony.
