Bigfoot (also known as Sasquatch) is a cryptid which supposedly is a simian-like creature of American folklore that is said to inhabit forests, especially in the Pacific Northwest. Bigfoot is usually described as a large, hairy, bipedal humanoid. Scientists discount the existence of Bigfoot and consider it to be a combination of folklore, misidentification, and hoax, rather than a living animal. They note the lack of physical evidence after centuries of investigation, despite the fact that numerous creatures would have to exist in order to maintain a breeding population. A small group of investigators are sustained in their interest by occasional new reports of sightings. Such reports are attributed to persons seeing various animals, particularly black bears.
