These are "kalong" (Javanese brown giant fruit bat), another collection of animals at Bandung Zoo.
"Kalong" (Pteropus Vamvyrus) is classified into the suborder of megabats (megachiroptera) or the giant bats. Because of what they eat and their behavior, megachiroptera is also called fruit bats or flying foxes. An adult "kalong" can reach about 60 centimeters in length (about 23.5 inches) and weigh about 1.5 kilograms (about 3.3 lbs) with wing span of about 1.5 meters (5 feet).
"Kalong" are fruit eaters (frugivores) and like most fruit bats they have big eyes and excellent sense of smell, which help them navigate in the dark - the time when they go out to eat - and find their food. For your information, most fruit-eating bats don't generally use echolocation.
"Kalong" is one of Indonesia's endangered animals and is protected by the law.
