The Rennell flying fox (Pteropus rennelli ) is a species of flying fox found in the Solomon Islands. It is an endangered species risking extinction.
The forearm of the holotype was 121 mm (4.8 in) long.The fur of its back is uniformly brownish, with the fur of its neck and face lighter.
It is only known from Rennell Island, which is part of the Solomon Islands.
Females give birth to one offspring per litter, with the young called a "pup."Its lifespan is estimated at 8–9 years.It is nocturnal, roosting in sheltered places such as trees during the day.Individuals roost by themselves.
The holotype was the only known individual of these species until 1958, when two more were collected.It is currently listed as an endangered species by the IUCN; its 2017 assessment uplisted it from its 2008 status of vulnerable. A 2016 study stated that the Rennell's flying fox is one of the land mammals most threatened by overhunting.Because the species has such a small range, it is susceptible to extinction via natural disaster; a single cyclone could conceivably extinct this species.
