The Molossidae, or free-tailed bats, are a family of bats within the order Chiroptera. The Molossidae is the fourth-largest family of bats, containing about 110 species as of 2012. They are generally quite robust, and consist of many strong-flying forms with relatively long and narrow wings with wrinkled lips shared through their genus. Their strong flying form allows them to fly 60 miles per hour using tail winds and at altitudes over 10,000 feet. This makes them unique among bats, as they are the only bat family that withstands the elevation. They are widespread, being found on every continent except Antarctica. They are typically found in caves, abandoned mines, or tunnels.
Mormopterus is a genus of molossid microchiropterans, small flying mammals referred to as free-tailed bats. The genus has been the subject of several revisions, and the diversity of taxa centred on Australia were separated to a new genus Ozimops, and two monotypic genera, Setirostris and Micronomus. The species of Mormopterus, in this stricter sense, are only found in areas outside of Australia and West Papua.
Wagner's bonneted bat or Wagner's mastiff bat, is a species of bat in the family Molossidae. It is found in the Americas from Argentina and Peru north to Mexico, and Cuba. Populations in Florida in the United States are now recognized as the Florida bonneted bat
The dwarf dog-faced bat is a species of free-tailed bat from South America. It is found in Argentina, Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Paraguay and Uruguay, typically at lower elevations. It is one of two species in the genus Molossops, the other being the rufous dog-faced bat. Three subspecies are often recognized, though mammalogist Judith Eger considers it monotypic with no subspecies. It is a small free-tailed bat, with a forearm length of 28.9–32.5 mm (1.14–1.28 in) and a weight of 5–8 g (0.18–0.28 oz); males are larger than females. It is brown, with paler belly fur and darker back fur. Its wings are unusual for a free-tailed bat, with exceptionally broad wingtips. Additionally, it has low wing loading, meaning that it has a large wing surface area relative to its body weight. Therefore, it flies more similarly to a vesper bat than to other species in its own family. As it forages at night for its insect prey, including moths, beetles, and others, it uses two kinds of frequency-modulated echolocation calls: one type is to navigate in open areas and to search for prey, while the other type is used for navigating in cluttered areas or while approaching a prey item.
The black mastiff bat is a bat species. It ranges from the northern region of South America, most of Central America and parts of southern Mexico.
Micronomus norfolkensis is a species of molossid bat, a family of flying mammals. The bat is endemic to Australia, where it occurs from southeastern Queensland to eastern New South Wales. They are the sole species of genus Micronomus and referred to by variations on east-coast free-tailed bat.
Ozimops planiceps is a small bat in the family Molossidae, native to Australia and Indonesia.
The Sumatran mastiff bat is a species of bat in the family Molossidae, the free-tailed bats. It is only known from Sumatra in Indonesia. It was described in 1907 and has not been recorded since.
Peters's wrinkle-lipped bat, also called Peters's goblin bat, is a species of bat in the family Molossidae, the free-tailed bats. It is endemic to Madagascar, where it is widespread and in some areas abundant. It commonly roosts in human-made structures, sometimes in colonies with other free-tailed bat species. It forages in the open, often in agricultural areas. The bat is sexually dimorphic, with males larger than females.
Kalinowski's mastiff bat is a species of bat in the family Molossidae, the free-tailed bats. It is native to Peru and northern Chile. Relatively little is known about the species, but it is thought to be common in its range. It is sometimes seen in urban areas. Molecular sequencing data indicates that the closest relatives of M. kalinowski are members of another genus, Nyctinomops.
The Incan little mastiff bat is a species of bat in the family Molossidae, the free-tailed bats. It belongs to the subgenus Micronomus.
Miller's mastiff bat is a species of bat in the family Molossidae. It is found in Brazil, Colombia, Costa Rica, Guyana, Mexico, Nicaragua, and Venezuela.
The Florida bonneted bat or Florida mastiff bat is a species of bat in the genus Eumops, the bonneted bats or mastiff bats. Until recently, it was classified as a subspecies of Wagner's bonneted bat. It is endemic to southern Florida in the United States. This species has one of the smallest geographical distributions of any New World bat. It has been called "one of the most critically endangered mammal species in North America". It is protected under the Endangered Species Act.
The Cuban greater funnel-eared bat is a species of funnel-eared bat. It is endemic to a cave in westernmost Cuba.
Setirostris eleryi is a species of small insectivorous bat found in inland eastern Australia. It is the sole species of the molossid genus Setirostris, a name that refers to the coarse bristles on their faces. Earlier common names have referred to this unique feature, and the 'free-tail' that is a common feature of its microchiropteran family, the Molossidae; no single common name emerged during the taxonomic revisions that identified what was referred to as the bristle-faced freetail.
Ozimops loriae is a species of bat found in Australia and Papua New Guinea.
Cynomops milleri is a species of bat that is native to South America. It was previously considered a subspecies of the Para dog-faced bat. It is considered a small- to medium-sized member of its genus. It is classified as least concern by the International Union for Conservation of Nature because it appears to be common and widespread. It is found in Venezuela, French Guiana, Guyana, Suriname, Brazil, and Peru.
Ozimops ridei is a species of molossid bat found in eastern Australia.
Ozimops petersi, the inland free-tailed bat is a species of bat found in Australia.
Ozimops lumsdenae is a species of molossid bat found in Australia, the largest of the genus Ozimops.
