Therianthropy refers to a person who identifies as a non-human animal on a non-physical level. They fall under the umbrella of Otherkin or people with alterhuman identities.

This is not a belief they are an animal or can transform in to one; rather a mental, psychological or spiritual identity as the animal (known as the theriotype).

The symbol is made up of two Greek characters the delta which is a triangle (symbolizing change and the shift in mentality from humanoid to animalistic) and the theta which is a circle with a line in the middle (referring to the ‘Th’ in therian, the name given to one with this identity).
