Cryptozoology

Cryptozoology is a pseudoscience involving the search for animals whose existence has not been proven. This includes looking for living examples of animals that are considered extinct, such as non-avian dinosaurs; animals whose existence lacks physical evidence but which appear in myths, legends, or are reported, such as Bigfoot, Chupacabra, Sasquatch, and Yeti; and wild animals dramatically outside their normal geographic ranges, such as phantom cats (also known as Alien Big Cats). Cryptozoology is not a recognized branch of zoology or a discipline of science. It is an example of pseudoscience because it relies heavily upon anecdotal evidence, stories and alleged sightings.
