The black-bearded tomb bat has a forearm length of 55–68 mm (2.2–2.7 in). It has a small "beard", or a tuft of black fur on its chin. Its fur is blackish-brown, with individual hairs white at the base.[4]
Biology and ecology
The black-bearded tomb bat is highly colonial, forming large aggregations of up to 15,000 individuals while roosting. These roosts are located in temples, ruins, or caves. It is a seasonal breeder; young are born after a gestation length of 120–125 days. The typical litter size is one individual, though twins have been documented.[4]
