The Rise of Therians: Exploring a Growing Identity Movement

In recent years, a unique subculture has gained visibility, particularly among young people in cities like Buenos Aires, and Montevideo. Individuals identifying as “therians” are increasingly appearing in public spaces, sparking both curiosity and debate. This phenomenon, amplified by viral videos on platforms like TikTok and Instagram, raises questions about self-expression, identity, and social boundaries.

What Does It Mean to Be a Therian?

The term “therian” originates from “therianthropy,” a Greek-rooted word combining “beast” and “human being.” Originally used in taxonomy and mythology, the concept evolved within digital communities in the 1990s. Today, it refers to individuals who experience a deep, internal identification – spiritual, psychological, or otherwise – with a non-human animal, known within the community as a “teriotype.” Common animal identifications include mammals like wolves, dogs, foxes, and felines.

How Therian Identity Manifests

Therians emphasize that their identity is not simply a costume or performance. It’s described as a profound, involuntary experience. Public expression often involves simple masks, tails, and “quadrobics” – moving on four limbs, mimicking animal movements. Videos showcasing these practices have gone viral on platforms like TikTok, contributing to the movement’s growing visibility.

The Phenomenon Gains Public Attention

The trend has moved beyond online spaces, with gatherings in public areas. In early February 2026, approximately 100 therians gathered in Plaza Independencia in Montevideo, and similar events occurred in Buenos Aires, Argentina. These gatherings have attracted both participants and media attention. Videos of individuals with animal masks moving on all fours have circulated widely, prompting discussion and debate.

Controversy and Social Debate

The increased visibility of therians has sparked controversy. While some defend the right to self-expression and identity diversity, others question the boundaries when these practices impact public spaces or others. Incidents, such as a reported biting incident in Buenos Aires, have further fueled the debate. The viral nature of the phenomenon has quickly brought a previously niche community into the public spotlight.
