Pteropus pelagicus is a species of fruit bat in the family Pteropodidae. It includes two subspecies that were formerly recognized as full species— Pteropus insularis (Chuuk flying fox) and Pteropus phaeocephalus (Mortlock flying fox).[3] It is endemic to Micronesia. It is threatened by habitat loss.
The species was described by German naturalist Heinrich von Kittlitz in 1836. He gave it the species name pelagicus from Ancient Greek πελαγικός 'of the open sea'.[4]
In 2013, a study was published that challenged the status of the Chuuk flying fox and the Mortlock flying fox as species. The study stated that the Chuuk flying fox was not significantly different from the Mortlock flying fox, and that they represent two subspecies of the same species, which should be called Pteropus pelagicus. They proposed that the Chuuk flying fox be referred to as P. p. insularis, and the Mortlock flying fox be referred to as P. p. pelagicus. The study also concluded that the closest relative of P. pelagicus is the Guam flying fox, based on morphology.[3] A 2014 study that used genetics also concluded that the Guam flying fox was the sister taxon to P. pelagicus.[5] There are currently two recognized subspecies of Pteropus pelagicus, both of which were formerly recognized as distinct species.
The authors of the 2013 study suggested that the common name of Chuuk flying fox be retained to refer to Pteropus pelagicus. They recommended it over the name "Mortlock flying fox" because there is a tradition of using geographic-based common names for flying foxes of the Caroline Islands.[3]
According to traditional classification, P. pelagicus is in the P. pselaphon species group.[6] However, more recent genetic analysis places it in the newly-described P. pelagicus species group, consisting of the following species:[5]
The heads of the adults are creamy white, buff, or tawny in adults. The heads of the juveniles are grayish brown, lacking red or yellow highlights. The back and rump are dark brown, with lighter hairs interspersed throughout. Their faces are dark brown to almost black, while the tops of the heads are brown or grayish brown. Their throats and chests are light brown or reddish brown, while their lower abdomen is darker brown. Many individuals have a large white patch on their bellies. Individual hairs are 14.7–16 mm (0.58–0.63 in) long. P. p. pelagicus has more contrast in its coloration than P. p. insularis, and they also tend to have larger abdominal white patches. Their forearms are 101–108.7 mm (3.98–4.28 in) long. They weigh 148–190 g (5.2–6.7 oz).[3]
P. p. pelagicus roosts in small groups of 5-10 individuals, although gatherings as large as 27 have been observed. They eat breadfruit, bananas, papaya, and Pandanus fruits. In July, many of the females have pups, though larger pups have also been observed in April. Copulation has been observed in December.[3]
P. p. insularis roosts in larger groups of up to 100 individuals; they are considered a "strongly colonial" species. Individuals are sometimes found by themselves, though. It is considered at least somewhat diurnal, unlike most flying foxes which are mostly nocturnal.[7]
P. pelagicus is located on the Nomoi Islands, Chuuk Lagoon, and Namonuito Atoll. All three locations are within the Federated States of Micronesia. P. p. pelagicus is found on the Nomoi islands, while P. p. insularis is located on the other two sites. The range of the two subspecies is separated by 171 km (106 mi).[8][6][9][10][11] The entire range of P. p. pelagicus is only 11.9 km2 (4.6 sq mi), with 75% of the population occurring on Satawan and Lukunor atolls.[3]
When they were still considered separate species, the IUCN assessed that both the Chuuk flying fox and the Mortlock flying fox were critically endangered.[12][13] The IUCN has not yet assessed the status of Pteropus pelagicus, however. P. p. pelagicus is threatened by climate change, as the atolls where they live are only 3–5 m (9.8–16.4 ft) above sea level. Climate change is also projected to increase the frequency and intensity of typhoons, which negatively impact both subspecies. Based on censuses, the population of P. p. pelagicus was estimated at 925–1,200 individuals in 2004. Unlike other species of flying fox, there does not appear to be much of a bushmeat trade in this species. Micronesians reportedly disdain flying foxes as food because they urinate on themselves and Micronesians view them as rat-like vermin. Other threats potentially include introduced predators such as cats, rats, and mangrove monitors.[3]
In 1986, there were an estimated 5,628 P. p. insularis, but a steep decline took place. In two years (1988-1989), 3,723 of them were exported to Guam for human consumption. P. p. insularis is not as threatened by climate change as the pelagicus subspecies, because its range has greater elevation.[12]
P. pelagicus was protected under CITES Appendix II in 1987, which was criticized by bat conservationists for not taking strict enough measures to protect flying foxes. It was protected under CITES Appendix I in 1989, making commercial trade of it illegal. [14]

La volpe volante di Chuuk (Pteropus pelagicus Kittlitz, 1836) è un pipistrello appartenente alla famiglia degli Pteropodidi, endemico della Micronesia.[1][2]
Pipistrello di medie dimensioni, con la lunghezza della testa e del corpo tra 131 e 186 mm, la lunghezza dell'avambraccio tra 101 e 115 mm, la lunghezza delle orecchie tra 20 e 24 mm e un peso fino a 245 g.[3][4]
La pelliccia è di lunghezza media, soffice e setosa. Il colore generale del corpo è bruno-nerastro, leggermente cosparso di peli grigiastri. Al centro dell'addome è presente una grossa macchia giallo-brunastra brillante o bianca. Le spalle variano dal bianco crema o giallo-brunastro dorato al fulvo. La testa è nerastra. Il muso è relativamente corto ed affusolato, gli occhi sono grandi, l'iride è marrone. Le orecchie sono di lunghezza media e con una leggera concavità sul bordo posteriore appena sotto l'estremità arrotondata. La tibia è priva di peli. Nelle femmine, e probabilmente anche nei maschi, sono presenti dei ciuffi di peli giallo-brunastri brillanti intorno a delle ghiandole situate sui lati del collo. È privo di coda, mentre l'uropatagio è ridotto ad una sottile membrana lungo la parte interna degli arti inferiori. La sottospecie P.p.pelagicus è più piccola ed ha le spalle color bianco crema divise da una banda longitudinale più scura.
Si rifugia in gruppi fino ad un centinaio di individui sugli alberi delle foreste. È una specie prevalentemente diurna.[5]
Si nutre di infiorescenze della Palma da cocco.
Femmine con piccoli ben sviluppati sono state osservate tra maggio e luglio.
Questa specie è diffusa sull'Atollo di Chuuk, sull'Atollo di Namonuito e nelle Isole Mortlock nella Micronesia.
Vive nelle foreste native montane.
Sono state riconosciute 2 sottospecie:
La IUCN Red List, considerato che la popolazione si è ridotta al 20% nelle ultime tre generazioni a causa della perdita del proprio habitat, classifica P. pelagicus come specie in grave pericolo (CR).[1]
La CITES ha inserito questa specie nell'appendice I.

De Chuukvleerhond (Pteropus insularis) is een vleermuis uit het geslacht Pteropus die voorkomt in de Micronesische deelstaat Chuuk. De soort is bekend van de atol Chuuk en is gezien op verschillende eilanden in de Mortlock-eilanden, ten zuidoosten van Chuuk zelf. De Chuukvleerhond is aan de rand van de afgrond gebracht door de jacht (er zijn veel exemplaren naar Guam verscheept omdat vleerhonden in de Marianen als een delicatesse worden gezien). Deze handel is echter nu verboden door de CITES.
De Chuukvleerhond is een kleine vleerhond met een donkerbruin lichaam. De borst is licht geelbruin, de bovenrug goud- tot geelbruin. De ondersoort phaeocephalus is wat lichter van kleur. De voorarmlengte bedraagt 101 tot 109 mm, de tibialengte 47,0 tot 48,5 mm en de oorlengte 21 tot 22 mm. De soort eet naar alle waarschijnlijkheid fruit zoals kokosnoten.
Deze vleermuis heeft de volgende ondersoorten:
