The Ahool has an ape-like face, large dark eyes, red-skinned wings, large claws on its forearms, and is covered in grey fur. It is said to have a wingspan of 12 feet, or 3 meters, twice the size of the largest bat known to man, the flying fox. One scientist theorized that the creature may be related to another cryptid, the Kongamato.
Female Ahools are very social, while the males live on their own. Living in groups, the females and their young remain together until the young are fully mature and capable of breeding. Ahools are omnivorous creatures, feeding on a large range of food sources, but will consume large amounts of flesh as they are very successful predators, preying on a range of large animals ranging from small cats to full grown humans. Ahools allegedly hunt their prey by upside-down stalking throughout the forest as the creature's large size proved to be easily noticeable if it were to stalk from the skies. Stalking usually lasts for several minutes before the Ahool drops down from the treetops to its victim, jaws open wide, and "engulf" their victim with their large wings while delivering a fatal bite with their massive fangs to the victim's neck, cracking the spine and usually kills the victim instantly.
