Members of Pteropodidae are known colloquially as the flying foxes, or Old World fruit bats. The family is composed of 41 genera and about 170 species. The most species-rich genus in the family is Pteropus with 59 species, many of which are island endemics. Body and wing size ranges from small (37 mm forearm length) to large (220 mm forearm length). The family boasts the largest bats in the world. Pteropus vampyrus individuals have a wingspan of up to 1.7 m. Pteropus giganteus individuals have a comparable wingspan but a greater mass, with males weighing between 1.3 and 1.6 kg. Pteropodids are strictly vegetarian, foraging for fruits, nectar, and pollen using their sight and a sensitive olfactory system. Bats of the genus Rousettus use tongue clicks as a crude form of echolocation while navigating in the dark. Some species are migratory, covering vast distances, while others have more moderate home ranges. Eidolon helvum individuals aggregate in numbers reaching the hundreds of thousands, yet many species roost with only a few conspecifics. Members of Pteropodidae service the ecosystems they inhabit by playing important roles as pollinators and seed dispersers.

Pteropodidae has a tropical and subtropical distribution in the Old World (eastern hemisphere). Species are found as far north as the eastern Mediterranean, continuing along the southern coast of the Arabian Peninsula and across South Asia. Species are found as far south as South Africa, the islands of the Indian Ocean, and to the northern and western coasts of Australia. The longitudinal range reaches from the Atlantic coast of Africa to the islands of the western Pacific. Pteropodids are absent from northwest Africa, southwest Australia, a majority of the Palearctic region, and all of the Western Hemisphere.

The head and body length of pteropodids varies from 50 mm to 406 mm. Despite size, many characteristics are shared among genera. A relatively long rostrum (pronounced in nectarivores), large eyes, and simple external ears give members of this family a dog or fox-like appearance (hence “flying fox”). The genera Nyctimene and Paranyctimene are exceptions in that they contain tubular nostrils that project from the upper surface of the snout. On the skull, postorbital processes are present over the orbital region. The palatine extends posterior to nearly cover the presphenoid. No more than two upper and two lower incisors are present in adults, otherwise cheek and canine dentition varies between species. The tongue is highly protrusible in nectar feeding bats and often complex with terminal papillae.
The chest is robust, comprised of the down-thrusting pectoralis and serratus muscles. The articulating regions of the humerus never come into contact with the scapula, which differs from a locking mechanism that occurs in the shoulder joint of other bat groups. The second digit is relatively independent from the third digit and contains a vestigial claw that adorns the leading edge of the wing.
Modifications for hanging include a relocation of the hip socket. The acetabulum is shifted upward and dorsally, and articulates with a large headed femur for a wider range of motion. In contrast to most other mammal orders, the legs cannot be positioned in a straight line under the body. In conjunction with large claws on their feet, pteropodids use a tendon-ratchet system that allows them to hang without prolonged muscular contraction. The legs manipulate a primitive uropatagium during flight. Aside from Notopteris, most species are tailless or with just a spicule of a tail.
Several species of Pteropodidae demonstrate sexual dimorphism. Males of Hypsignathus monstrosus have rather outlandish facial features, while females have the conservative fox-like look. Males of the genus Epomops have distinctive white patches in association with a glandular membrane on their shoulders, whereas females do not. Considering the whole family, males are generally larger than females. The penis of all pteropodids is a pendant and freely movable organ, resembling that of Primates. Juveniles are typically naked or have a velvety coat that is darker than adult pelage.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: sexes alike; male larger; sexes colored or patterned differently; ornamentation

Pteropodids typically occur in primary or maturing secondary forests. A few species inhabit savannah habitats where they roost in bushes and low trees. Over half of the 41 genera are made up of species that roost in trees. Gregarious species roost on the open branches of large, canopy-emergent trees. Pteropodids that roost singly or in small groups can be found in dead palm leaves, aerial roots, and even arboreal termite nests. These bats also tend to have cryptic coloration and wrap themselves with their wings in order to resemble dead leaves. In one species, Cynopterus sphinx, individuals construct tents by chewing folds in palm leaves. Caves, cliff walls, mines, and the eaves of buildings also serve as roosting locations for species in 17 genera. Most cave-dwelling species are limited to the lit areas near the opening, while members of the genus Rousettus are able to navigate the darker regions using crude echolocation.
Flowering plants are essential to the diet of pteropodid species; therefore, flying foxes mostly use woodlands or orchards for food. Canopy emergent fruiting trees, such as fig and baobab trees, are frequently used as a food source. The flowers of baobab trees have a strong fragrance and are located on the crown of the tree, which makes them easily accessible to bats (a flower syndrome known as chiropterophily). Many pteropodid species are found in coastal areas and drink salt water in order to supplement nutrients lacking in their diet.
A few species are migratory. Eidolon helvum individuals gather in large numbers and migrate hundreds of kilometers northward with seasonal rains, only to return to southern Africa at the end of the rainy season. Pteropus scapulatus populations make major, and somewhat erratic movements within Australia, following the flowering periods of Eucalyptus trees. Many species of Pteropus roost on islands and make daily migrations to the mainland for foraging. Some species range from sea level to 2500 m, yet little is known about any significant elevational migrations.
Habitat Regions: tropical ; terrestrial
Terrestrial Biomes: savanna or grassland ; forest ; rainforest
Other Habitat Features: suburban ; agricultural ; riparian ; estuarine
Pteropodids are frugivorous and nectarivorous. Some species also eat flowers of the plants they visit. Foraging habits are not well documented, though many species of the genus Pteropus rely heavily on figs. Many species rely on broad array of resources, though there may be a functional dichotomy between large species that rely heavily on canopy resources and smaller species that can use understory resources. Some larger species can use the claws on their thumbs and second digits to climb into the understory and seek out fruit that is hidden or inaccessible by flight.
Primary Diet: herbivore (Frugivore , Nectarivore )
Pteropodids provide important pollination and seed dispersal services to a wide range of plants. On islands in the south Pacific, pteropodids are the principle pollinators and dispersers of plants. Many plants have adaptations specifically for seed dispersal and pollination by bats, such as fruiting or flowering at the ends of branches and at bat accessible locations in the canopy. Eidolon dupreanum has been shown to likely be the sole pollinator of the baobab tree Adansonia suarezensis in Madagascar.
Ecosystem Impact: disperses seeds; pollinates

Birds of prey and carnivorous mammals, as well as snakes and large lizards may prey on pteropodids. Pteropodids tend to have fewer predators on islands. However, there have been several cases of introductions of non-native, arboreal snakes which have decimated pteropodid populations.

Life History and Behavior
Pteropodids rely heavily on vision and olfaction when navigating and foraging. Intraspecific communication is often vocal. In some species, such as Pteropus poliocephalus, vocal signaling may be associated with specific motor activities which enhance the meaning of the vocal signal. In species such as Eidolon helvum, sexually dimorphic sebaceous glands which are larger in males may provide olfactory behavioral cues.

Pteropodids have been known to live at least 30 years, both in captivity and in the wild.
Mating behavior in pteropodids is highly variable, and much is unknown. The males of one genus (Hypsignathus) set up lekking territories twice a year and draw in females with unique vocalizations and wing-flapping displays. Male epauletted fruit bats (genus Epomophorus) often display their concealed epaulets (hair tufts near the shoulder) and emit courting calls to attract females. Many species form harems consisting of 1 dominant male and up to 37 females, while bachelor males roost separately.
Mating System: polygynous ; polygynandrous (promiscuous)
While most bats have one reproduction event per year, many pteropodids are polyestrous, with two seasonal cycles corresponding to the annual wet and dry seasons. Usually one young is born per pregnancy, but twins are not uncommon. Upon fertilization, ova implantation in the uteri can be immediate or delayed, probably in response to the environment. Development of the embryo (once implanted) may also be delayed, probably to ensure birth at a time when fruit is available during the rainy seasons. One species, Macroglossus minimus, exhibits asynchronous breeding and sperm storage, suggesting the importance of birth during an optimal (rainy) season.
Pregnant females usually leave social roosts to form nursery groups with other pregnant females. Females in nursery roosts form their own social network and take care of each other through mutual grooming. Gestation periods usually lasts 4 to 6 months, but can be longer if implantation is delayed. Birth patterns of pteropodids have been widely studied and usually occur during the wet periods both in the northern latitudes (February to April) and the southern latitudes (August to November). Species that are polyestrous will give birth during both of these rainy seasons. It is predicted that birth during these seasons yields high survival rates because lactation occurs when fruit availability is at a maximum. Birth is followed by postpartum estrous and subsequent mating. After weaning, young may stay with their mothers up to 4 months. Sexual maturity in juveniles is reached by 2 years old or earlier. Female sexual maturity is reached earlier than in males.
Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous ; delayed implantation ; post-partum estrous
Female pteropodids are primarily responsible for rearing the young. Lactation lasts anywhere from 7 weeks to 4 months, and the mother may care for her young slightly longer. In one genus (Dyacopterus), males with functional mammary glands have been reported lactating, which suggests the sharing of juvenile care among both parents.

Many factors threaten pteropodids throughout their range. Human activities have decimated populations of certain species directly through hunting or indirectly through habitat destruction. In Asia and Australia, deforestation is the most important contributor to pteropodid population decline. Some species are vulnerable to typhoons and hurricanes which may destroy roosting habitat on islands. The IUCN Red List of Threatened Species lists 5 species as recently extinct, 10 species as critically endangered, 19 species as endangered, 15 species as near threatened, and 39 species as vulnerable, suggesting that nearly half of all pteropodid species face significant threats to population viability.

Relevance to Humans and Ecosystems
Many crop species are attractive food sources for pteropodids. Because cultivars are often developed from wild species, these commercial crops have the same characteristics that wild plants evolved to attract bats to their fruit. Fruit growers have experimented with visual, audio, and olfactory deterrents as well as electric wire to keep pteropodids from eating their crops. Pteropodids may also be dispersers of invasive plant species, as they consume crops introduced for cultivation and may disperse the seeds into natural habitat. Pteropodids have been indicated as reservoirs for a variety of viruses such as Ebola and other viruses in the family Paramyxoviridae. Hendra virus, Menangle virus, and Nipah virus have all been linked to pteropodids.
Negative Impacts: injures humans (carries human disease); crop pest
Larger species of pteropodids are hunted for their meat. Both subsistence and commercial hunting of Pteropus species have been reported. Consumer demand for Pteropus species on the island of Guam has been so great that it has resulted in the extinction of at least one species in the Pacific region. Flying foxes are also important in the dispersal and pollination of economically important plants. They attract tourists in some areas and produce accumulations of guano that can be used as fertilizer.
Positive Impacts: food ; ecotourism ; produces fertilizer; pollinates crops
Megabats constitute the suborder Megachiroptera, family Pteropodidae of the order Chiroptera (bats). They are also called fruit bats, Old World fruit bats, or, especially the genera Acerodon and Pteropus, flying foxes. Fruit bats are restricted to the Old World in a tropical and subtropical distribution, ranging no further than the eastern Mediterranean and South Asia, and are absent from northwest Africa and southwest Australia.
Megabats, however contrary to their name, are not always large; the smallest species is 6 cm (2.4 in) long and thus smaller than some microbats. The largest attain a wingspan of 1.7 m (5.6 ft), weighing in at up to 1.6 kg (3.5 lb). Most fruit bats have large eyes, allowing them to orient themselves visually in twilight and inside caves and forests.
Their sense of smell is excellent. In contrast to the microbats, the fruit bats do not use echolocation (with one exception, the Egyptian fruit bat Rousettus egyptiacus, which uses high-pitched tongue clicks to navigate in caves).
Loss of echolocation
Megabats make up the only family (Pteropodidae) in order Chiroptera that is not capable of laryngeal echolocation, unlike the microbat. Echolocation and flight evolved early in the lineage of chiropterans and echolocation was later lost in family Pteropodidae. Both echolocation and flight are energetically expensive processes for bats. The nature of the flight and echolocation mechanism of bats allows for creation of echolocation pulses with minimal energy use. Energetic coupling of these two processes is thought to have allowed for both energetically expensive processes to evolve in bats. The loss of echolocation may be due to the uncoupling of flight and echolocation in megabats. The larger average body size of megabats compared to echolocating bats suggests that a larger body size disrupts the flight-echolocation coupling and made echolocation too energetically expensive to be conserved in megabats.
Behavior and ecology
Megabats mostly roost in trees and shrubs. Only those that possess echolocation venture into the dark recesses of caves. Because they eat fruit, some megabat species are unpopular with orchard owners. Megabats are frugivorous or nectarivorous, i.e., they eat fruits or lick nectar from flowers. Often, the fruits are crushed and only the juices are consumed. The teeth are adapted to bite through hard fruit skins. Large fruit bats must land to eat fruit, while the smaller species are able to hover with flapping wings in front of a flower or fruit.
Frugivorous bats aid the distribution of plants (and therefore forests) by carrying the fruits with them and spitting the seeds or eliminating them elsewhere. Nectarivores actually pollinate visited plants. They bear long tongues that are inserted deep into the flower; pollen passed to the bat is then transported to the next blossom visited, thereby pollinating it. This relationship between plants and bats is a form of mutualism known as chiropterophily. Examples of plants that benefit from this arrangement include the baobabs of the genus Adansonia and the sausage tree (Kigelia).
As disease reservoirs
|This section may need to be rewritten entirely to comply with Wikipedia's quality standards. (December 2014)|
Fruit bats have been found to act as reservoirs for a number of diseases that are fatal to humans and domestic animals, but the bats themselves sometimes have no signs of infection.  A different species has emerged in Ivory Coast, another West African country, just east of Guinea and Liberia. According to a study, the virus in West Africa seems to have diverged from its lineage in Central Africa just within the past decade. It somehow leapfrogged over or around the Ivory Coast ebolavirus to situate itself in southeastern Guinea. That suggests the unnerving prospect that the Central African ebolavirus (the only one strictly known as Ebola virus) is expanding its range, either by infecting new populations of reservoir hosts or by migrations of those host animals.
Three species of bats tested positive for Ebola, but had no symptoms of the virus. This indicates the bats may be acting as a reservoir for the virus. Of the infected animals identified during these field collections, immunoglobulin G (IgG) specific for Ebola virus was detected in hammer-headed bats, Franquet's epauletted fruit bats, and little collared fruit bats.
Other viral diseases which can be carried by fruit bats include Australian bat lyssavirus and Henipavirus (notably Hendra virus and Nipah virus), both of which can prove fatal to humans. These bats have been shown to infect other species (specifically horses) with Hendra virus in Australian regions. Later, humans became infected with Hendra virus after being exposed to horse body fluids and excretions.
Fruit bats are considered a delicacy by South Pacific Islanders, as well as in Micronesia. Consumption has been suggested as a cause of Lytico-Bodig disease on the Micronesian island of Guam, through bioaccumulation of a plant toxin to which the bats are immune.
Bats are usually thought to belong to one of two monophyletic groups, a view that is reflected in their classification into two suborders (Megachiroptera and Microchiroptera). According to this hypothesis, all living megabats and microbats are descendants of a common ancestor species that was already capable of flight.
However, other views have been shared, and a vigorous debate persists to this date. For example, in the 1980s and 1990s, some researchers proposed (based primarily on the similarity of the visual pathways) that the Megachiroptera were in fact more closely affiliated with the primates than the Microchiroptera, with the two groups of bats having therefore evolved flight via convergence (see Flying primates theory). However, a recent flurry of genetic studies confirms the more longstanding notion that all bats are indeed members of the same clade, the Chiroptera. Other studies have recently suggested that certain families of microbats (possibly the horseshoe bats, mouse-tailed bats, and the false vampires) are evolutionarily closer to the fruit bats than to other microbats.
