A bandersnatch is a fictional creature in Lewis Carroll's 1871 novel Through the Looking-Glass and his 1874 poem The Hunting of the Snark. Although neither work describes the appearance of a bandersnatch in great detail, in The Hunting of the Snark, it has a long neck and snapping jaws, and both works describe it as ferocious and extraordinarily fast. Through the Looking-Glass implies that bandersnatches may be found in the world behind the looking-glass, and in The Hunting of the Snark, a bandersnatch is found by a party of adventurers after crossing an ocean. Bandersnatches have appeared in various adaptations of Carroll's works; they have also been used in other authors' works and in other forms of media. Source: Wikipedia (en)
