The Ahool – A Mysterious Giant Bat of Indonesia

Have you ever heard of the Ahool? It’s a giant bat that dwells in the rainforests of Java, Indonesia. With its 10 foot (3 meters) wingspan and large claws at the end of its forearms, this creature has been sighted several times but still remains shrouded in mystery.

It was first discovered in 1925 by Dr. Ernest Bartels, who watched it emerge from behind a waterfall towards dusk and heard its distinctive cry—a long “Ahoooool” as it flew overhead. Let’s take a look at what we do know about this mysterious creature.

Physical Characteristics & Habitat

The Ahool is similar to the Olitau, another huge bat with a 10-foot wingspan that inhabits Southeast Asia. But compared to other species of bats, the Ahool stands out for its unique physical features like its long tail and unusually large claws on its forearms which are believed to help it cling to rocks or tree trunks. It also appears to have longer fur than other bats, which helps keep it warm during cold nights in the Java rainforest where it makes its home.

Diet & Behavior

As for diet, there is speculation that Ahools feed mainly on fish or small aquatic animals found near rivers and lakes in their habitat area. They may also feed on insects or even larger animals such as birds and rodents; however, this has yet to be confirmed since there is still very limited information about their behavior and habits in the wild. What we do know is that they are active mostly during twilight hours when they come out of their caves and roosting spots to hunt for food.

Conservation Status

Unfortunately, due to deforestation and human encroachment into their habitat areas, the population size of these mysterious creatures is unknown but likely decreasing rapidly each year due to the loss of food sources and suitable living space. As such, conservation efforts must be taken soon if we want future generations of humans to be able to experience these majestic creatures firsthand!


The Ahool has remained an enigma for almost 100 years since Dr Ernest Bartels first observed it emerging from behind a waterfall with its distinctive cry ringing through the air—a long “Ahoooool” as it flew overhead. From what we know so far about this mysterious creature—its massive size, unique physical features like large claws on its forearms which help them cling onto rocks or tree trunks, preferred time of activity during twilight hours etc—it seems clear that more research must be done if we’re going to prevent further population decline due to human encroachment into their habitat areas.
