Sheath-tailed Bat
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 mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dentition
Dentition pertains to the development of teeth and their arrangement in the mouth. In particular, it is the characteristic arrangement, kind, and number of teeth in a given species at a given age. That is, the number, type, and morpho-physiology (that is, the relationship between the shape and form of the tooth in question and its inferred function) of the teeth of an animal. Terminology Animals whose teeth are all of the same type, such as most non-mammalian vertebrates, are said to have '' homodont'' dentition, whereas those whose teeth differ morphologically are said to have '' heterodont'' dentition. The dentition of animals with two successions of teeth (deciduous, permanent) is referred to as '' diphyodont'', while the dentition of animals with only one set of teeth throughout life is ''monophyodont''. The dentition of animals in which the teeth are continuously discarded and replaced throughout life is termed '' polyphyodont''. The dentition of animals in which the teeth ...

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.

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 ...

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.

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''.

Asia
Asia ( , ) is the largest continent in the world by both land area and population. It covers an area of more than 44 million square kilometres, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilisations. Its 4.7 billion people constitute roughly 60% of the world's population. Asia shares the landmass of Eurasia with Europe, and of Afro-Eurasia with both Europe and Africa. In general terms, it is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a social constructionism, historical and cultural construct, as there is no clear physical and geographical separation between them. A commonly accepted division places Asia to the east of the Suez Canal separating it from Africa; and to the east of the Turkish straits, the Ural Mountains an ...
