Also known as Cuero, this is a mythological creature from the traditions of southern Chile. It is said of the manta that it inhabits lakes and rivers, appearing as a cowhide floating on the water. Upon reaching its victim, it wraps around them, trapping them with its claws and sucking them in with its suckers. In other versions, it is said that instead of claws it has eyes along its edges. It thus shares some similarities with the myth of the piuchén.
