Cryptozoologists aim to prove the existence of organisms from folk lore like big foot, chupacabra, Loch Ness monster etc. These organisms are referred to as cryptids. This branch of science falls under the category of pseudoscience because the usual scientific methods are not used here. It neither falls under the category of zoology nor under the category of folkloristics. Rather on depending on facts and true evidence, it usually depends on word of mouth anecdotal information. Hence, it is also criticized sometimes for not being a true science field.
Because though it is a field of study aimed at proving the existence of mystery animals these animals have never been seen by the human eye and they also are superstitious in existence, unlike other animals we know 100% exist. Therefore this cannot be considered true science.
