Ahool
The island of Java is rumored to be the home of a giant bat-like creature named after its strange blood-curdling howl. The Ahool is said to be roughly the size of a human toddler with a wing-span of nearly 12 feet. With sharp claws and powerful, leathery wings, this terrifying beast is able to snatch its prey from above. It was first sighted in 1925. Some theories regarding what the animal might be range from a large owl to a possible pterosaur.
