Yacuruna

Mythical water people of the Amazon who abduct humans.

The Yacuruna are a mythical water people from the Amazon basin, said to dwell in splendid underwater cities located where rivers meet. The name comes from the Quechua words *yaku* ("water") and *runa* ("man"). This belief is held most strongly by indigenous communities throughout the Amazon.

These beings are depicted as hairy, with feet that are deformed and a head that faces backward. Illustrations often show a man-like Yacuruna riding a crocodile and accompanied by a serpent. Many consider the Yacuruna a god capable of transforming into an attractive human male. At night, they travel through the rainforest on black crocodiles used as canoes. During the day, they sleep at the bottom of rivers and lakes, keeping one eye open. They can talk to and fully control all aquatic animals in the Amazon. Locals believe Yacuruna can change into Amazon river dolphins, which are drawn to the scent of blood from menstruating women. When such a woman is found, the Yacuruna becomes a handsome, charming man and uses aphrodisiacs to kidnap her, taking her to his underwater kingdom.

The underwater cities inhabited by the Yacuruna are said to mirror human cities upside down, sometimes appearing as reflections on the water’s surface. Inside, the Yacuruna live in crystal palaces with walls made of multicolored fish scales and pearl. They recline in hammocks of feathers under mosquito nets of butterfly wings; the hammocks themselves are snakes, and the seats are turtles.

Yacuruna are dangerous spirits that lure people into the water by taking human forms. When fishermen, husbands, or young girls (who later turn up mysteriously pregnant) vanish from Amazonian communities, it is often believed they have been seduced and captured by the Yacuruna. Abducted victims slowly transform into Yacuruna themselves: first their eyes change, then their head and feet turn backward so they cannot find their way home and must continue to the underwater city. This transformation is permanent, and the victim can never return. Don Juan Flores Salazar tells a story of his little sister being taken while swimming. Years later he saw her alive but turned into a mermaid; she had married a Yacuruna and become a healer of the waters. He believed it was her destiny, as he was a healer of the land.

Lore & Background

The Yacuruna is described as hairy with a backward-facing head and deformed feet. Illustrations depict it as a man-like creature accompanied by a serpent and riding a crocodile. It is considered by many to be a god who can change into an attractive man. The Yacuruna roam the Amazon rainforest at night using black crocodiles as canoes, and during the day they sleep at the bottoms of rivers and lakes with one eye open. They can communicate with aquatic animals and maintain ultimate control over them. Locals believe Yacuruna can transform into Amazon river dolphins, which are attracted to the odor of blood in menstruating women. Once such a woman is found, a Yacuruna will transform into a handsome man and use aphrodisiacs to kidnap her, bringing her into his underwater kingdom.

Yacuruna are said to inhabit underwater cities that mirror upside-down human cities, often interpreted as reflections on the water's surface. Within the city, they live in palaces of crystal with multicolored walls of fish scales and pearl, reclining on hammocks of feathers under mosquito nets of butterfly wings. The hammocks are snakes, with turtles for seats.

Yacuruna can be characterized as dangerous spirits who lure humans into the water by taking on human forms. When people of the Amazonian community disappear—such as fishermen, husbands, and young girls who become mysteriously pregnant—it is often assumed they have been seduced and captured by the Yacuruna. Abducted victims gradually transform: first their eyes turn to resemble the Yacuruna, then their head and feet turn backward so they cannot find their way home. Transformation is irreversible. Don Juan Flores Salazar describes a story of how his little sister was taken by a Yacuruna while swimming; years later he saw her alive but transformed into a mermaid, married to a Yacuruna, and she had gained knowledge as a healer of the waters.

Reader's Guide

The Yacuruna hold significance in Amazonian indigenous belief as both dangerous spirits and sources of shamanic power. They explain mysterious disappearances of fishermen, husbands, and young girls, and serve as a cultural framework for understanding events such as unexpected pregnancy or loss. The Yacuruna's ability to be summoned by a shaman as a familiar highlights their dual role: they can pass on healing knowledge to a sick person or shaman, establishing trust, and then turn the person's head forward again, allowing return to the human world. A Yacuruna can be the source of shamanic powers, becoming a powerful ally. This reflects a worldview where the spiritual and natural worlds are intertwined, and where transformation—both physical and social—is possible through contact with these water spirits. The story of Don Juan Flores Salazar's sister illustrates how abduction can be reinterpreted as destiny and the acquisition of healing knowledge. The Yacuruna thus embody both peril and potential for spiritual growth within Amazonian cosmology.
