Bismark Flying Fox, Ahool, Olitiau, or Kongamato
According to mainstream science, the world's largest bat is the Bismark Flying Fox, an animal that never gets larger than a six feet wingspan. According to cryptozoology, mainstream scientists might be wrong. Many sightings from seemingly reliable people suggest that this might not be the case. A number of bat species that are just as big or bigger might be out there, waiting for science to formally recognize them. The island of Java, not very far from the Bismark flying fox's home of New Guinea, is supposed to harbor a bat with a twelve-foot wingspan called the ahool. It cries sound like "A-hool" and it eats fish. It has gray fur and a flattened face with huge black eyes, with its head overall looking like a monkey's head. It is not attributed with supernatural powers, and seems like such a plausible animal that it has drawn the attention of naturalists. If a giant bat lived anywhere, the dense rainforests of Java would be a likely place.
Another plausible place for an undiscovered giant bat to live is Cameroon, a country in Africa where scientists have reported seeing a very similar bat. This creature is apparently called the olitiau by locals. It also has a twelve-foot wingspan and a monkey-like face, but its fur is pure black. It is regarded with a great deal of superstition and fear. It is not improbable that both of these bats might have monkey-like faces. Bats have a notoriously wide variety of head shapes, and many known species have heads resembling different animals such as foxes, dogs, lemurs or even horses!
Another possible African giant bat is the kongamato, which has also been interpreted as a pterosaur by some cryptozoologists. This creature is not quite so large, has reddish fur, and has a long snout instead of a flattened face. Madagascar, a large island just off the coast of Africa, has tales about a bat called the fangalabolo, with a wingspan larger than 5 feet, bigger than any other bat known to live in Madagascar. The Guiafairo of Senegal is described as a giant bat that is very smelly and often manages to terrify people by making its way indoors. It is hated very much, and its name translates to "the fear that flies by night." The mlularuka of Tanzania is perhaps the most tame and ordinary of undiscovered African bats. Like known species of giant bats, it is a fruit-eater and thus is mainly spoken of as a pest to agriculture. It is described as being the size of a dog.
But this was not reported in Africa, New Guinea, or the island of Java. This sighting, and human attack happened in Tora Bora Afghanistan, and happened on film by Marines. These 3 men were in a cave and there was several bat creatures, or Cave Demons. This could also have been An Olitiau, also known as the Death Bat or Night Flyer. The Olitiau is a gigantic humanoid cryptid bat (or flying reptile) hypothesized to exist in Central Africa.
There are many plausable explanations to what exactly attacked these men, and how they managed to get into the caves. The caves were riddled with booby traps, and the one Corporal Wade set off, sent him tumbling 12 - 15 feet, and right into the path of these Cave Demons. Perhaps the Bat people were placed there by the enemy, after the traps were set. After all, animals all over the world can be imported, if you have the right connections.
Whatever it was down in that cave of Afghanistan, Bat People, Cave Demons, or just Giant Bats, it will remain a mystery.
