Luzon fruit bat

The Luzon fruit bat (Otopteropus cartilagonodus) is a small megabat of the family Pteropodidae, the only species in the genus Otopteropus and endemic to the island of Luzon in the Philippines. It is dark blackish brown with a lighter, usually grey belly, is nocturnal and has rather large eyes for its size, and it is recognisable by the red thickenings on its ears. The skull shows sexual dimorphism: it is larger in males, while females have a more heightened braincase and a longer total body length. Its natural habitat is subtropical or tropical dry forest. It is one of two species of the family that have radiated in Southeast Asia. The Wikipedia list of pteropodids gives its IUCN status as least concern, with a declining population.
