The Biak naked-backed fruit bat (Dobsonia emersa) is a species of megabat in the family Pteropodidae. It is endemic to Indonesia.
The Biak naked-backed fruit bat was first described as a species in 1985. Its species name "emersa" is from Latin " emergere ," meaning "to emerge." Bergmans and Sarbini selected this name because zoologists such as Fredericus Anna Jentink had written about Dobsonia species from this area long ago, but had overlooked this taxon. [2]
It has a curved snout and relatively large eyes. Its teeth are small and narrow. Adults have a forearm length of approximately 114 mm (4.5 in) and weigh 169–180 g (6.0–6.3 oz). [2]
It is endemic to Indonesia. It is a lowland species, found at 0–30 m (0–98 ft) above sea level. It occupies both primary and secondary forests. [1]
As of 2020, it is evaluated as a vulnerable species by the IUCN. It meets the criteria for this classification because it is known from fewer than five locations. It is susceptible to population decline via overhunting and disturbance of its roost sites. [1]
The Schouten Islands are an island group of Papua province, eastern Indonesia in the Cenderawasih Bay 50 km off the north-western coast of the island of New Guinea. The group consists of the main islands of Biak, Supiori and Numfor, and numerous smaller islands, mostly covered in rain forest.
The Philippine naked-backed fruit bat or Philippine bare-backed fruit bat is a megabat that mostly lives on Negros Island. Two small populations were also found on Cebu Island in the Philippines. Like other bare-backed fruit bats, its wings meet along the midline of their bodies, making it a very agile flier. It roosted in caves, in areas where little light penetrated the gloom. It was so abundant once that it left piles of guano, which were used by miners as fertilizer.
The bare-backed fruit bat or Moluccan naked-backed fruit bat is a fruit bat in the family Pteropodidae.
Beaufort's naked-backed fruit bat is a species of megabat in the family Pteropodidae. Its natural habitat is in caves.

The Panniet naked-backed fruit bat, also known as the De Vis's Bare-backed Fruit Bat and Panaeati Bare-backed Fruit Bat, is a species of megabat in the family Pteropodidae. It roosts in groups, within caves and tree hollows.
The western naked-backed fruit bat is a species of megabat in the family Pteropodidae. It is endemic to Indonesia. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.
The New Britain naked-backed fruit bat is a species of megabat in the family Pteropodidae. It is endemic to New Britain island in northern Papua New Guinea.
The greenish naked-backed fruit bat is a species of megabat in the family Pteropodidae.
The Biak roundleaf bat or Geelvinck Bay leaf-nosed bat is a species of bat in the family Hipposideridae. It is endemic to the Biak Islands and Cenderawasih Bay area of Papua Province, located in Western New Guinea, Indonesia.
The demonic tube-nosed fruit bat is a species of bat in the family Pteropodidae. It is endemic to Papua New Guinea. The holotype specimen was collected in 1979 on New Ireland, in the Bismarck Archipelago. It was described as a new species in 1983. The range of the species may extend to other islands, however the extent of the range is not presently known.

Andersen's naked-backed fruit bat or Andersen's bare-backed fruit bat is a large cave-dwelling species of megabat in the family Pteropodidae. It is endemic to the Bismarck Archipelago including the Admiralty Islands in Papua New Guinea.
The Halmahera naked-backed fruit bat is a common and widespread species of megabat in the family Pteropodidae. It is endemic to Indonesia. It is assessed as least-concern by the IUCN as it has a wide range and seems to have no significant threats.
