The northern free-tailed bat (Chaerephon johorensis) is a species of bat in the family Molossidae. It is found in Indonesia and Malaysia.
It was described as a new species in 1873 by Irish zoologist George Edward Dobson. Dobson had obtained the holotype from James Wood-Mason. Dobson initially placed it in the genus Molossus and the subgenus Nyctinomus, with a scientific name of Molossus (Nyctinomus) johorensis. [2] Its species name "johorensis" is Latin for "belonging to Johor." Johor is a state in Malaysia; the holotype was collected there.
Its ears are large and round. Its tragi are small and squarish in shape. Its ears are connected to each other by a band of tissue called the interaural membrane. As a free-tailed bat, its tail extends beyond the uropatagium. Its dental formula is 2.1.2.34.1.2.3, for a total of 36 teeth. [2]
It is currently listed as vulnerable by the IUCN. It meets the criteria for this designation because its population have declined by more than 30% from 2004–2014. [1]
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.
The northern freetail bat is a species of bat found in Yapen, Seram Island, Western New Guinea and Northern Australia.
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.
