Cryptozoology

Cryptozoology (from Greek κρυπτός, kryptos, "hidden" + zoology; literally, "study of hidden animals") refers to the search for animals which are considered to be legendary or otherwise nonexistent by mainstream biology. This includes looking for living examples of animals which are extinct, such as dinosaurs; animals whose existence lacks physical support but which appear in myths, legends, or are reported, such as Bigfoot and Chupacabra; and wild animals dramatically outside of their normal geographic ranges, such as phantom cats or "ABC"s (an acronym commonly used by cryptozoologists that stands for Alien Big Cats).
