Bigfoot is described as a large, hairy, muscular, bipedal ape-like creature, roughly 6 inches to 9 inches tall. The top of its head is similar to the male gorilla, with a strong, unpleasant smell. The creature’s footprint is claimed to be as large as 24 inches long and 8 inches wide. Some footprint casts have also contained claw marks. The proponents of Bigfoot’s existence claim that the creature is omnivorous and mainly nocturnal. However scientists discount the existence of Bigfoot and consider it to be a combination of folklore, misidentification, and hoax, rather than a living animal, because of the lack of physical evidence.
