The Large flying fox (Pteropus vampyrus), also known as the greater flying fox, Malaysian flying fox, large fruit bat, kalang or kalong, is a species of megabat in the Pteropodidae family. Like the other members of the genus Pteropus, or the Old World fruit bats, it feeds exclusively on fruits, nectar and flowers. It is noted for being one of the largest bats. It, as with all other Old World fruit bats, lacks the ability to echolocate.
