Emballonuridae
Emballonuridae is a family of microbats, many of which are referred to as sac-winged or sheath-tailed bats. They are widely distributed in tropical and subtropical regions around the world. The earliest fossil records are from the Eocene. Description The emballonurids include some of the smallest of all bats, and range from 3.5 to 10 cm in body length. They are generally brown or grey, although the species of genus '' Diclidurus'' are white. The faces are said to be handsome, the heads being comparable to those of domestic dogs, and their wings are long and narrow. As with other microchiropteran families, they use ultrasonic echolocation to sense the surrounding environment and their prey; the signals of some species are unusual in being audible to humans. Possession of the postorbital processes, the reduced, noncontacting premaxillaries, and rather simple shoulder and elbow joints, which is similar to pteropodids, makes them rather a primitive group. However, they are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gray Sac-winged Bat
The gray sac-winged bat (''Balantiopteryx plicata'') 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 . Name Wilhelm Peters first described the bat in 1867. The name ''Balantiopteryx'' comes from the Greek, meaning "pouch wing"; "''plicata''" is from a Latin word meaning "folded".#ArroyoCabrales, Arroyo-Cabrales & Jones (1988), p. 3. In English, ''Balantiopteryx plicata'' is known as the gray sac-winged bat, and less commonly, Peters' sac-winged bat. The general name for these and other bats of the family Emballonuridae are sheath-tailed bats. Taxonomy ''Balantiopteryx plicata plicata'' and ''Balantiopteryx plicata pallida'' are both subspecies of ''Balantiopteryx plicata''.#ArroyoCabrales, Arroyo-Cabrales & Jones (1988), p. 1.

Taphozous
''Taphozous'' is a genus of the family Emballonuridae. The wide distribution of the genus includes several regions of Australia, Indonesia, Papua New Guinea and Africa. ''Taphozous'' comes from the Greek τάφος, meaning "a tomb". The common names for species include variants on sac-winged, sheathtail, or tomb bats. The genus is the type for a grouping within the family, subfamily Taphozoinae, and an arrangement that describes two subgenera is as follows: subgenus ''Taphozous'' (''Liponycteris'') * Hamilton's tomb bat (''Taphozous hamiltoni'') * Naked-rumped tomb bat (''Taphozous nudiventris'') subgenus ''Taphozous'' (''Taphozous''), * Indonesian tomb bat (''Taphozous achates'') * Coastal sheath-tailed bat (''Taphozous australis'') * Common sheath-tailed bat (''Taphozous georgianus'') * Hildegarde's tomb bat (''Taphozous hildegardeae'') * Hill's sheath-tailed bat Hill's sheath-tailed bat (''Taphozous hilli'') is a bat of the family Emballonuridae.

Diclidurus
''Diclidurus'' is a genus of bats whose common name is the ghost bats (not to be confused with the Australia ''Macroderma gigas''). ''Diclidurus'' all inhabit tropical South America, and ''D. albus'' is also found in Mexico and Central America.Emmons, L.H (1997). ''Neotropical Rainforest Mammals.'' 2nd edition. The fur of these insectivorous bats is white, sometimes with a slight greyish tinge, except ''D. isabella'', which is partially pale brown. The only other all-white bat in the New World is the Honduran white bat, but it is easily distinguished from ''Diclidurus'' by its relatively large nose leaf. ''Diclidurus'' are poorly known and only infrequently captured, at least in part because they fly high above the ground or in the forest canopy (above the typical height of mist nets used by bat researchers).Ferreira, A.P.; D.C. Melo; and A. Loures-Ribeiro (2013). ''Diclidurus albus Wied-Neuwied, 1820 (Chiroptera: Emballonuridae): First record of the species in the state of Paraí ...

Ecuadorian Sac-winged Bat
The Ecuadorian sac-winged bat (''Balantiopteryx infusca'') is a species of sac-winged bat in the family Emballonuridae. It is found in Colombia and Ecuador. According to the IUCN Red List of Threatened Species, the population trend is decreasing for this species, due to habitat destruction through deforestation. In 2013, Bat Conservation International listed this species as one of the 35 species on its worldwide priority list for conservation. Taxonomy ''Balantiopteryx infusca'' is the sister species of ''Balantiopteryx io'' and there are no recognised subspecies.Gardner, Alfred L. ''Mammals of South America''.

Thomas's Sac-winged Bat
Thomas's sac-winged bat (''Balantiopteryx io'') is a species of sac-winged bat in the family Emballonuridae. It is found in Belize, Guatemala, and Mexico. Taxonomy Oldfield Thomas named this bat in 1904. It is presumed that he named it after the Io found in Greek mythology, who was cursed by Hera to be eternally chased, because bats seem to be “flighty.” ''Balantiopteryx io'' is a sister species of '' Balantiopteryx infusca'' and has no recognised subspecies.Gardner, Alfred L. ''Mammals of South America''. Chicago: University of Chicago, 2008, p. 194. Appearance It is the smallest species when compared to others in the genus ''Balantiopteryx,'' and lacks the white trim that is characteristic of '' Balantiopteryx plicata''. The males weigh about 3.7 g, while the females weigh about 5 g. Biology and behavior Thomas's sac-winged bat prefers to live in caves near the entrance, but there have been instances where they have been found deeper in the caves where it is darker. It ha ...

Echolocation (animal)
Echolocation, also called bio sonar, is a biological active sonar used by several animal groups, both in the air and underwater. Echolocating animals emit calls and listen to the echoes of those calls that return from various objects near them. They use these echoes to locate and identify the objects. Echolocation is used for navigation, foraging, and hunting prey. Echolocation calls can be frequency modulated (FM, varying in pitch during the call) or constant frequency (CF). FM offers precise range discrimination to localize the prey, at the cost of reduced operational range. CF allows both the prey's velocity and its movements to be detected by means of the Doppler effect. FM may be best for close, cluttered environments, while CF may be better in open environments or for hunting while perched. Echolocating animals include mammals, especially odontocetes (toothed whales) and some bat species, and, using simpler forms, species in other groups such as shrews. A few bird speci ...

Thomas's Shaggy Bat
The Thomas's shaggy bat (''Centronycteris centralis'') 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. Taxonomy It was described as a new species in 1912 by British mammalogist Oldfield Thomas. The holotype had been collected by H. J. Watson in 1898 in Panama. Its species name "'' centralis''" is Latin for "in the middle." Description The fur of its back is gray while the fur around its eyes and near its uropatagium is reddish. Its ventral fur is yellowish. Despite being in the sac-winged bat family, it lacks wing sacs. It is a small species, with individuals weighing only . Its forearm length is approximately . Its dental formula is for a total of 32 teeth. Biology and ecology It is nocturnal, roosting in sheltered places during the day such as hollow trees. It forages for its insect prey with a "slow and maneuverable" flight. It is usually found at low elevat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microbats
Microbats constitute the suborder Microchiroptera within the order Chiroptera (bats). Bats have long been differentiated into Megachiroptera (megabats) and Microchiroptera, based on their size, the use of echolocation by the Microchiroptera and other features; molecular evidence suggests a somewhat different subdivision, as the microbats have been shown to be a paraphyletic group. Characteristics Microbats are long. Most microbats feed on insects, but some of the larger species hunt birds, lizards, frogs, smaller bats or even fish. Only three species of microbat feed on the blood of large mammals or birds ("vampire bats"); these bats live in South and Central America. Although most "Leaf-nose" microbats are fruit and nectar-eating, the name “leaf-nosed” isn't a designation meant to indicate the preferred diet among said variety. Three species follow the bloom of columnar cacti in northwest Mexico and the Southwest United States northward in the northern spring and then the ...
