Therian identities are diverse and expressed in a wide variety of ways. Therians often identify as one or more animal species that exist in real life, called their theriotype; theriotypes can be extinct or extant species. Those who identify with more than one animal are referred to as "polytherians". The most common species therians identify as are
wolves,
dogs,
foxes, and
felids such as
panthers or housecats, though can include any animal, such as
horses,
deer, other
mammals,
insects,
aquatic life,
avians,
invertebrates,
reptiles, and
dinosaurs. Some identify not as a specific species, but rather a taxonomic
genus or
family; this experience is called "cladotherianthropy", after the word
clade, and those who experience it are called "cladotherians". Unlike
clinical lycanthropy, which is linked to belief in actual physical transformation into an animal, therians consider their identity strictly non-physical. Therians often describe going through an "awakening" where they first discover and accept their identity.
Shifts Many therians experience shifts, which refer to a temporary change, commonly in behavior or mindset, that brings them closer to their identified animal. However, reported shift experiences also include a wide range of other forms beyond these two. Shifts can occur in a range of situations, from everyday play and relaxation to moments of intense emotion such as fear or anger, and individuals differ in how frequently and intensely they experience them. It is reported that mental shifts may be associated with both positive and negative emotions, including feelings of threat or anger as well as comfort or euphoria when acting in animal-like ways.
Instincts Personal accounts from therians commonly describe various species‑related
instincts or urges associated with their theriotype, the origins of which are often reported as difficult to explain in terms of typical human emotions or experiences. These may take different forms and can relate to play, defense, cooperation, display of affection, or predatory impulses (
prey drive). Their expression can include nonverbal expressions such as movements, gestures, or postures. They may also involve lifestyle-related needs or preferences, such as sleeping in ways reminiscent of the theriotype, seeking environments natural to the corresponding species, or expressing a desire to move or vocalize in species-typical ways. == Common activities ==
