Cryptids are creatures or beings whose existence is suggested by purported sightings, folklore, or other evidence, but which are not recognized by mainstream science. These creatures often exist in the realm of urban legends, myths, and folklore, with reported sightings typically lacking credible evidence. Some famous examples of cryptids include Bigfoot, the Loch Ness Monster, the Chupacabra, and the Yeti. While many cryptids are associated with supernatural or paranormal phenomena, others may have more mundane explanations, such as misidentified animals or hoaxes. Cryptid research is often conducted by cryptozoologists, who study these creatures and attempt to gather evidence of their existence.
