The Aru flying fox (Pteropus aruensis) is a Critically Endangered species of megabat found in the Aru Islands in Indonesia. It was described by Wilhelm Peters in 1867. [1] It was formerly considered a subspecies of the black-bearded flying fox. [2] The species is poorly known, and has not been encountered since the 19th century. It is classified as critically endangered by the IUCN and is listed on CITES appendix II. [1]

Taxonomy

As the Pteropus genus is quite speciose, it is further divided into species groups. The Aru flying fox is placed in the livingstonii species group. Other members of this species group include:

There is ongoing debate about whether the Aru flying fox is a distinct species. [1] Some believe that it is a subspecies of the black-bearded flying fox, [4] while others believe that it is distinct enough to be considered a species. [5]

Description

They are similar in appearance to the black-bearded flying fox. [6] The fronts of their heads are a combination of gray, black, and yellowish-white. The backs of their heads are rust-colored, and their chins are a deep red. Their necks are rust or rust-brown in color, creating the appearance of a chestnut collar. [7] [6] Their backs are glossy, yellowish-white, with some black hairs sprinkled throughout. [7] [6] Their lower ventral sides are variable in color, and can be black and rusty yellow, or black and rusty brown. Their upper ventral sides along the sternum are dark brown to black. [7] Their forearms are 190–191 mm (7.5–7.5 in) long. [5]

Conservation

This species is possibly extinct. In 2017, a statistical model assessed the extinction probability of 23 mammal species that have been missing since the 19th century. The Aru flying fox was one of the five species that the model determined was almost certainly extinct. There has not been a confirmed sighting of this species since 1877. [8] The IUCN currently lists this species as critically endangered on the basis that there are most likely fewer than 50 remaining. Expeditions sponsored by the Western Australia Museum in the 1990s were unsuccessful in locating any individuals. However, a toothless jawbone discovered in 1992 "probably represents this species." It is a large and colorful bat, so it is speculated that hunting played a role in its decline and possible extinction. [1]

The Mariana fruit bat, also known as the Mariana flying fox, and the fanihi in Chamorro, is a megabat found only in the Mariana Islands and Ulithi. Habitat loss has driven it to endangered status, and it is listed as threatened by the US Fish and Wildlife Service. Poaching, habitat loss, and the introduction of invasive species have contributed to the species' decline.

<i>Pteropus</i> Genus of large bats

Pteropus is a genus of megabats which are among the largest bats in the world. They are commonly known as fruit bats or flying foxes, among other colloquial names. They live in South Asia, Southeast Asia, Australia, East Africa, and some oceanic islands in the Indian and Pacific Oceans. There are at least 60 extant species in the genus.

<i>Acerodon</i> Genus of bats

Acerodon is a genus of bats in the family Pteropodidae containing five species, all native to forests in Southeast Asia, and all considered threatened. They are closely related to Pteropus. These bats are considered herbivores(frugivore)and feed on leaves and fruits. They can usually be found in a tropical forest or in a swamp like wetland.

The Banks flying fox is a species of megabat in the family Pteropodidae. It is endemic to Vanuatu. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical swamps. These small fruit bats are about 15 cm. long with grey and brown on its head and back with a yellow-orange neck and yellow-gray bellies. Its diet consists of coconut flowers and Vaveli trees fruit since its home is tropical.

<span class="mw-page-title-main">Gray flying fox</span> Species of mammal

The gray flying fox is a species of flying fox in the family Pteropodidae. It is not to be confused with the grey flying fox. It is found in Indonesia, but not in the Philippines, despite occasional reference to such. Very little is known about this species. The gray flying fox has small size and neutral coloration with a brownish head and an orange abdomen. It probably roosts individually or in small groups. It was listed on appendix II of CITES, and is classified as "Data Deficient" by the IUCN. This species has been decimated by hunting for bushmeat in Indonesia. The hunters use fishing hooks, ropes, and other supplies to hunt the bats. The ropes and hooks are placed along their flight paths, tearing and ensnaring the bats' wings when are flying. In the course of a hunting season, entire colonies can be killed.

<span class="mw-page-title-main">Okinawa flying fox</span> Species of bat

The Okinawa flying fox is a species of megabat in the genus Pteropus. It is endemic to possibly Japan. It was previously listed as extinct by the IUCN, but because the two known specimens are taxonomically uncertain and of unknown provenance, it was changed to 'Data Deficient'. Some place this animal into synonymy under Pteropus mariannus. Two specimens are in the British Natural History Museum, and the whereabouts of the third is unknown. Two of the specimens are believed to have come from Southeast Asia, so the true distribution of the Okinawa flying fox is unknown.

The black-bearded flying fox is an endangered species of megabat in the genus Pteropus. It is endemic to Indonesia, found on the islands of Ambon, Buru, Seram, Banda, and Yamdena. Currently considered monotypic, it formerly included the Aru flying fox and Kei flying fox as subspecies.

<span class="mw-page-title-main">Great flying fox</span> Species of mammal

The great flying fox, also known as the greater flying fox or Bismarck flying fox, is a species of megabat in the genus Pteropus, found throughout lowland areas of New Guinea and in the Bismarck Archipelago. Conflicting evidence suggests that its closest relative is either the spectacled flying fox or, jointly, the Pelew and insular flying foxes. Two subspecies are recognized. At up to 1.6 kg (3.5 lb) in weight, it is among the heaviest bats in the world and the largest bat in Melanesia. It is a gregarious animal which roosts with hundreds or thousands of individuals. In part due to its wide variation in color, it has many taxonomic synonyms, including Pteropus degener, Pteropus papuanus, and Pteropus sepikensis. It may forage during the day or night in search of fruit, including figs or fruits from the family Sapotaceae. It is considered a least-concern species by the IUCN, though its numbers have been negatively impacted by what appeared to be a disease, as well as by hunting for bushmeat that occurs across its range.

<span class="mw-page-title-main">Ceram fruit bat</span> Species of bat

The Ceram fruit bat or Seram flying fox is a species of megabat in the family Pteropodidae. It is endemic to the mountainous forests of two Maluku islands, Buru and Seram, including the Manusela National Park on Seram. They were once present on the nearby Ambon Island, but probably not anymore. The habitat has an area of less than 20,000 km2, and is decreasing due to logging. For this reason, and because of hunting by the local population, these species are listed as vulnerable by the IUCN since 1996.
