Cryptids are animals or beings claimed to exist but lacking scientific proof, originating from folklore, sightings, or legends, like Bigfoot or the Loch Ness Monster. Studied in cryptozoology, They are unconfirmed biological creatures, not supernatural monsters, potentially undiscovered species, with famous examples including Mothman, Yeti, and Chupacabra, though some creatures once considered cryptids (like the Komodo Dragon or Giant Panda) were later proven real. Key characteristics, Unproven Existence: Their existence isn't scientifically verified, relying on eyewitness accounts, folklore, or anecdotal evidence. Biological Basis: They are generally considered animals, not spirits, ghosts, or purely mythical beings, though some blur the lines.
