A Camahueto is a mysterious sea creature from the mythology of the Chiloé Archipelago in Chile. It is said to be in the form of a calf or bull and has a single horn protruding from it's head. The creature is said to be born in freshwater but migrates towards the sea as soon as its born. They are also said to be carnivorous, eating fish as well as man.
The Camahueto's horn is said to be valued by many and can be used in medicines that can rejuvenate men. The horn is also said to be able to be planted and from it another Camahueto will be born. A machi (shaman) is said to stalk every newborn Camahueto, hunting for it's horn. If the machi captures the creature with their lassos, they will remove the horn, which the Camahueto can regrow, and sell it or turn it into medicine. One use of the horn is to scrape shavings from it into a mixture of sea water and apple cider until it turns into vinegar and coarse salt. This mixture is said to restore the vitality of older men.
