The term "cryptozoology" refers to the search for mythical or hidden animals. Cryptozoologists, both amateurs and professionals, most often search for animals whose existence is denied by mainstream biologists. Additionally, their searches primarily focus on large animals, such as dinosaurs or the creature known as Bigfoot. The Loch Ness monster is one of the most well-known cryptids, and cryptozoologists have been seeking proof of Nessie's existence for years.
Anthonie Cornelis Oudemans' book The Great Sea Serpent, written in 1892, is considered the first scholarly work published on the subject of cryptozoology. However, the practice has been around almost as long as humans have walked the Earth. Due to the availability of technology such as GPS and satellite imaging, cryptozoology seems poised to become a popular new science.
