Morphology

The fringe-lipped bat has wart-like bumps on its lips and muzzle, which give it its name. The bat has an overall color of a reddish brown with gray on its belly. The fur is long and woolly. It is medium in size, about 32 grams.Garog, A. 1999.''Trachops cirrhosus'' (On-line), Animal Diversity Web. accessed December04, 2008 a

The tail is short. It has a nose-leaf with serrated edges. It has two pairs of lower incisors with three pairs of lower premolars. The molars have tubercular depressions with w-shaped cusps. The rostrum is shorter than the braincase but equal to the width of the braincase. It has a low wing-aspect ratio and high wing loading.Cramer, M.J., Willig, M.R., & Jones, C. 2001.''Trachops cirrhosus''. Mammalian Species.656:1-6.

Reproduction and development

The fringe-lipped bat generally mates during the dry season in the tropics, usually from January to June. There is no real difference in appearance between the male and the female. It gives birth to one offspring at a time. The young can stay with the parents for a considerable amount of time.)

Behavior

''Trachops cirrhosus'' roost in groups of up to 50 individuals and both sexes roost together. They emerge from the roosts early when there is still daylight because that is the best time to hunt

s. They hunt in continuous flight or sally out from perches. They hunt by following sounds of insects and frogs and also by using echolocation. Some frog species, such as '' Smilisca sila'', have evolved methods of acoustic crypsis to confuse auditory predators like ''T. cirrhosus''. This is done by synchronizing the timing of calls.

Conservation

The current conservation status of ''Trachops cirrhosus'' is least concern because its populations are currently stable.* Because it is stable there are no conservation action plans. But because of its feeding habits, it is placed in a precarious position that puts it at a risk from human activity.
