Not to be confused with the cryptid Chilean manatee or the water cow.
La Vaca Marina is a wekufe — a malevolent spirit from southern Chilean (Mapuche and Chilote) folklore. According to oral tradition, her origin lies in the mythic battle between Kai Kai Vilú and Trentren Vilú, the serpent gods of sea and land. During the great flood sent by Kai Kai, a helpless cow drowned, and the sea deity, moved by pity or twisted amusement, transformed her soul into a vengeful aquatic spirit.
La Vaca Marina appears at first glance as a healthy, fat, and content cow — seemingly mundane, yet unmistakably unnatural upon closer inspection. Some say she has flippers instead of legs, while others claim she walks beneath the waves using supernatural force. Some fishermen whisper that she can alter her limbs at will, adapting to land, sea, or river.
Her mission is clear: undo terrestrial fertility, starting with bulls.
La Vaca Marina is said to seduce bulls near the shore, calling them with mournful bellows or strange beauty. The mating is described as so ecstatically unnatural that bulls become obsessed. They refuse to breed with ordinary cows, stop eating, and try to flee their pens to return to the sea — often leading to their sacrifice at the hands of desperate farmers.
From these unholy unions, La Vaca Marina gives birth to camahuetos in rivers — monstrous one-horned bovine-like beings associated with destruction and fertility, mirroring the chaos she brings.

But her seduction is not limited to beasts, la Vaca Marina is a shapeshifter. She can appear as a voluptuous, busty woman — alluring and unnaturally charismatic. As a woman, she targets lonely fishermen, seducing them with promises of warmth, sex, and mystic pleasure. Those who lie with her are said to abandon their families, wander the shores in a daze, and lose all desire to reproduce. They become infertile men of the sea, spiritually tethered to her, Though few dare to hunt her, it is said her presence is marked by dead fish, missing bulls, and pale, moonstruck men seen staring toward the ocean.
Theories:[]
Some believe La Vaca Marina may be a misidentified sea cow (like a manatee or dugong), known for their vaguely cow-like faces. Given that Chile's waters are too cold for known sirenians, any such animal would be undocumented or extinct. A cold-water-adapted sirenian could be the basis — an aquatic mammal with flipper-like limbs, rare and elusive, rarely surfacing.
