Rousettus
''Rousettus'' is a genus of Old World fruit bats or megabats, referred to as rousette bats. The genus is a member of the Family_(biology), family Pteropodidae. The genus consists of seven species that range over most of Africa to southeast Asia, and the islands of the south Pacific. They are among the few megabats capable of echolocation, and the only genus of megabats known to use vocal echolocation.

Egyptian Fruit Bat
The Egyptian fruit bat or Egyptian rousette (''Rousettus aegyptiacus'') is a species of megabat that occurs in Africa, the Middle East, the Mediterranean and the Indian subcontinent. It is one of three ''Rousettus'' species with an African-Malagasy range, though the only species of its genus found on continental Africa. The common ancestor of the three species colonized the region in the late Pliocene or early Pleistocene. The species is traditionally divided into six subspecies. It is considered a medium-sized megabat, with adults weighing and possessing wingspans of approximately . Individuals are dark brown or grayish brown, with their undersides paler than their backs. The Egyptian fruit bat is a highly social species, usually living in colonies with thousands of other bats. It, along with other members of the genus ''Rousettus'', are some of the only fruit bats to use Animal echolocation, echolocation, though a more primitive version than used by bats in other families.

Old World Fruit Bat
Megabats constitute the family Pteropodidae of the order Chiroptera. They are also called fruit bats, Old World fruit bats, or—especially the genera '' Acerodon'' and ''Pteropus''—flying foxes. They are the only member of the superfamily Pteropodoidea, which is one of two superfamilies in the suborder Yinpterochiroptera. Internal divisions of Pteropodidae have varied since subfamilies were first proposed in 1917. From three subfamilies in the 1917 classification, six are now recognized, along with various tribes. As of 2018, 197 species of megabat had been described. The leading theory of the evolution of megabats has been determined primarily by genetic data, as the fossil record for this family is the most fragmented of all bats. They likely evolved in Australasia, with the common ancestor of all living pteropodids existing approximately 31 million years ago. Many of their lineages probably originated in Melanesia, then dispersed over time to mainland Asia, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Madagascan Rousette
The Madagascan rousette (''Rousettus madagascariensis'') or Madagascar rousette, is a species of megabat in the family Pteropodidae endemic to Madagascar. Its natural habitat is subtropical or tropical dry forests. Description The Madagascan rousette is a small fruit bat, the smallest of the three fruit bats endemic to Madagascar. The upper part of their bodies have a greyish fur while the underparts have a paler grey tinge. Like many other fruit bats, Madagascan rousettes have very dog-like faces with long, pointed snouts, large, wide eyes and largely separated ears. Like some other members of the genus ''Rousettus'', these bats reside within cave roosts, suggesting the use of echolocation. These bats are a part of a larger group of fruit bats within ''Rousettus'' which consists of 10 different species. The Madagascan rousette primarily resides on western islands of the Indian Ocean.

Geoffroy's Rousette
Geoffroy's rousette (''Rousettus amplexicaudatus'') is a species of megabat or Old World fruit bats. It is one of ten species in the genus ''Rousettus''. Distribution Geoffroy's rousette occurs throughout Southeast Asia and in the Malesia region of Oceania, in Myanmar, Thailand, Cambodia, Laos, Vietnam, Singapore, Indonesia, the island of Borneo, East Timor, the Philippines, the Solomon Islands, Bismarck Archipelago, and Papua New Guinea. Description Like other fruit bats, ''R. amplexicaudatus'' has sensitive hearing and sense of smell and good eyesight which helps it to manoeuvre well during flight, specifically at night. What makes it different from other fruit bats is its echolocating ability. It can be distinguished by its grey-brown to brown upperpart which is darker on top of the head and paler underpart which is usually grey-brown.Payne, J. & Francis, C.M. (1985).

Bare-backed Rousette
The bare-backed rousette (''Rousettus spinalatus'') is a species of megabat. Taxonomy and etymology It was described as a new species in 1980 by Bergmans and Hill. The holotype was collected in 1977 in northern Sumatra. The species name "''spinulatus''" is from Latin ''spina'' meaning "spine" and ''ala'' meaning "wing;" the scientific name refers to the fact that the wings insert along the spine rather than the sides of the body, which is unique in the genus ''Rousettus''. Description The bare-backed rousette is a small megabat with a cone-shaped snout. Its face has a number of small warts on its chin, around its mouth, and between its upper lip and eyes. Its wings are short and broad. Its forearm length is approximately . Individuals weigh . Biology It is nocturnal, roosting in sheltered places during the day such as caves. They navigate and potentially locate food resources using a primitive form of echolocation. They create high-pitched buzzing calls by moving the tongue ag ...

Bat Genera
Bats are flying mammals of the Order (biology), order Chiroptera (). With their forelimbs adapted as Bat wing development, wings, they are the only mammals capable of true and sustained Bat flight, flight. Bats are more agile in flight than most birds, flying with their very long spread-out digits covered with a thin membrane or patagium. The smallest bat, and arguably the Smallest organisms, smallest extant mammal, is Kitti's hog-nosed bat, which is in length, across the wings and in mass. The largest bats are the flying foxes, with the giant golden-crowned flying fox (''Acerodon jubatus'') reaching a weight of and having a wingspan of . The second largest order of mammals after rodents, bats comprise about 20% of all classified mammal species worldwide, with over 1,400 species. These were traditionally divided into two suborders: the largely fruit-eating megabats, and the Animal echolocation, echolocating microbats. But more recent evidence has supported dividing the or ...
