El Cuero

El cuero, literally "the hide," is an aquatic monster from the folklore of Chile's southern lake district, described as resembling a flattened, circular animal skin or cowhide floating on the surface of lakes and rivers, edged all around with claws, sharp bone hooks or eyes instead of fur. By the early twentieth century accounts of the creature were widespread enough to be recorded alongside other Chilean lake beings in Julio Vicuña Cifuentes's 1915 survey of oral tradition. It lures swimmers or animals close by appearing harmless, then unfurls itself over the victim like a blanket, gripping with its rim of claws and dragging them underwater to drown and devour them, leaving no trace but ripples. Stories from lakeside communities around Villarrica, Ranco and Panguipulli warned children and travelers never to swim in certain still, dark-watered coves said to be the creature's territory, and disappearances were sometimes attributed to an encounter with el cuero. Folklorists connect the legend to older South American beliefs about lake-dwelling shape-shifting spirits, and see it as a safety myth discouraging risky swimming in dangerous waters, dressing an ordinary danger in monstrous form.
