Distribution of the fringe-lipped bat |
The fringe-lipped bat (Trachops cirrhosus) is a leaf-nosed bat from southern Mexico to Bolivia and southern Brazil. It has three subspecies and no known fossils. It is the only species within its genus.
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. [2]
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. [3]
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. [3]
Its preferred habitat is near ponds or streams. It roosts in trees or hollow logs and sometimes in caves. It likes tropical dry and moist forests. Trachops cirrhosus is an opportunistic foliage-gleaning omnivore, eating mainly insects with some lizards, frogs (such as Hyalinobatrachium fleischmanni), [4] [5] fruits, and seeds. In rare cases this species has been idententified eating bats such as Furipterus horrens . [6] It sometimes shares roosts with other species of bats. It is sometimes preyed upon by gray four-eyed opossums. [3]
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 frogs. They hunt in continuous flight or sally out from perches. They hunt by following sounds of insects and frogs [4] and also by using echolocation. [3] 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. [7]
The current conservation status of Trachops cirrhosus is least concern because its populations are currently stable. [8] 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. [2]

He is credited with protecting the Austin Congress Avenue Bridge bat colony from extermination.

The short-eared bat is a bat species found in Brazil, Costa Rica, Guyana and Nicaragua. It is the only species within its genus.
The northern ghost bat is a bat species from South America, Trinidad, and Central America. It is a relatively rare, completely white, insectivorous bat, with an unusual sac at the base of its tail.
The black-winged little yellow bat is a species of vesper bat native to Central America.
The little white-shouldered bat is a species of bat from South and Central America. It is the only species within its genus, the name of which translates as "reaper" or "destroyer".
The little big-eyed bat is a bat species from South and Central America.
The pygmy fruit-eating bat is a bat of the family Phyllostomidae. The specific name phaeotis is of Greek derivation, coming from the word phaios meaning dusky, referring to their dusky gray coloration.
The great stripe-faced bat or stripe-faced vampire bat is a bat species found from southern Mexico to Bolivia and northwestern Brazil, as well as on Trinidad. The great stripe-faced bat is a frugivore. It is one of two species within the genus Vampyrodes the other being Vampyrodes major.
The gray sac-winged bat is a species in the family Emballonuridae which comprises the 51 species of sac-winged bats. It is found in Mexico from Baja California Sur and Sonora to Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica and northern Colombia, at elevations up to 1,500 metres (4,900 ft).
The Panama cross-banded tree frog or pug-nosed tree frog is a species of frog in the family Hylidae found in the humid Pacific lowlands of southwestern Costa Rica to eastern Panama and in the Caribbean lowlands of Panama and northern Colombia. Males of the species utilize synchronous calling to hide their position from predators. Females create basins during amplexus and deposit fertilized eggs onto the surface of the water.
The gray short-tailed bat, or Hahn's short-tailed bat, is a species of bat in the family Phyllostomidae native to Mexico and Central America.
The wrinkle-faced bat is a species of bat in the family Phyllostomidae and the only identified member of the genus Centurio. This bat is found in various countries in and around Central America. It eats fruit but is not classified within the fruit bats, and is instead classified as a leaf-nosed bat even though it does not have a leaf nose. It has an unusually shaped skull which is thought to allow it to eat a wider range of foods than other bats.
Underwood's bonneted bat is a species of bat in the family Molossidae.
The Sinaloan mastiff bat is a species of bat in the family Molossidae, native to Mexico, Central America and northern South America.
The Antillean ghost-faced bat is a species of bat in the family Mormoopidae. It is found in the Greater Antilles: Cuba, Hispaniola Jamaica, and Puerto Rico.
The sooty mustached bat is a species of bat in the family Mormoopidae. It is found in throughout the Greater Antilles, in Cuba, Hispaniola, Jamaica, and Puerto Rico.
The Thomas's shaggy bat is a bat species from Central and South America. It was previously included in the shaggy bat but Simmons and Handley (1998) showed that the species were distinct.
Sowell's short-tailed bat is a common bat species in the family Phyllostomidae. It is found from San Luis Potosi (Mexico) through Central America to west Panama. The species is named after American philanthropist James N. Sowell.
The Cozumelan golden bat is a bat species found in Mexico, Guatemala, Belize, Honduras, Nicaragua, Costa Rica, Panama and Colombia. At one time, this species was considered to be a subspecies of the golden bat. Little is known about the biology of this bat, but it has a wide range, no particular threats have been identified, and the population seems steady, so the International Union for Conservation of Nature has assessed its conservation status as being of "the least concern".
