large flying fox

The world's largest bat species, large flying foxes have wingspans reaching 1.5 meters and inhabit tropical forests from Southeast Asia to the Philippines and Indonesia. Despite the alarming name, they feed exclusively on fruit and nectar, making them vital pollinators and seed dispersers for tropical forest trees. Roost in massive colonies of thousands. Listed as Vulnerable due to hunting for bushmeat and habitat destruction.
