The Indian flying fox is one of the largest of all bats and has a wingspan of more than four feet. It does not prey on animals, feeding, instead, almost exclusively on a variety of fruit. The Indian flying fox was named for the shape of its head and its reddish brown fur, which resemble those of a fox. Flying foxes are the largest of all bats and are found widely throughout Asia and Australia.
