Therianthropy is the ability of human beings to metamorphose into animals by means of shapeshifting. It is possible that cave drawings found at Les Trois Frères, in France, depict ancient beliefs in the concept. The most well known form of therianthropy is found in stories concerning werewolves. They also called were-animals. It can be anything , any animal in the world.
Therianthropy, derived from the Greek therion and anthrōpos refers to beings that are partly human and partly animal, and in this sense is synonymous with the fandom's term furry. It has often been used to describe mythological creatures and deities, and has recently taken on a specialized meaning. Sometimes shortened to "therian," it is today used to describe members of a spiritually oriented subculture.
One way the term therianthropy has been used, as early as 1901, is in reference to transformation folklore of Asia and Europe. Therianthropy was also used to describe spiritual belief in animal transformation in 1915 and one source raises the possibility the term may have been used in the 16th century in criminal trials of suspected werewolves.
