The large flying fox (Pteropus vampyrus), also known as the greater flying fox, Malaysian flying fox, large fruit bat, kalang or kalong, is a southeast Asian species of megabat in the family Pteropodidae. 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.
The large flying fox is among the largest species of bat. It weighs 0.65–1.1 kg (1.4–2.4 lb) and has a wingspan of up to 1.5 m (4 ft 11 in). As with all megabats, it has a fox-like face, hence its name. It lacks a tail and has pointed ears. The hairs on much of its body are long and wooly, but are shorter and more erect on the upper back.The mantle hairs tend to be the longest. The color and texture of the coat differ between sexes and age classes.Males tend to have slightly stiffer and thicker coats than females. Immature individuals are almost all dull gray-brown.Young have a dark-colored mantle that becomes lighter in males when they mature. The head has hairs that range in color from mahogany-red and orange-ochreous to blackish. The ventral areas are brown or blackish, tinged with chocolate, gray or silver. The mantle can vary from pale dirty-buff to orange-yellow, while the chest is usually dark-golden brown or dark russet. The large flying fox has a large and robust skull. The dental formula is 18.104.22.168.3.2.3. It has a total of 34 teeth.[dubious ] The large flying fox’s wings are short and somewhat rounded at the tips. This allows them to fly slowly, but with great maneuverability. The wing membranes are only haired near the body.
