Cryptids are animals not recognised by science, or considered extinct but could still be alive. Cryptids are for the most part creatures of myth and legend, creatures thought to be extinct but may still exist, or animals that may have taken new evolutionary paths and evolved into something new.
Cryptozoology is the study of cryptids. For the most part cryptozoology is the study of mythical creatures but in a scientific fashion. Cryptozoologists are those that study cryptids and cryptozoology. Although crpytozoology is not an official proffesion.
