Cryptozoology is a pseudoscience concerned with the study of alleged animals. That is, creatures which have been attested to exist in folklore or urban legends, but whose real existence has not been confirmed by mainstream zoology. It's a wide-reaching field, with creatures of interest ranging from the down-to-earth bipedal apes like Bigfoot and the Yeti, to the more out-of-this-world Mothman, and even real extinct species like the thylacine, whose survival continues only in anecdotes.

Nearly all of the alleged animals studied by cryptozoologists will, in all likelihood, never be proven real. However, understanding the stories these creatures inhabit can give useful insight into popular culture, folklore, and the cryptozoology subculture - both online and in the wild.
