Nguruvilu
The Nguruvilu or Guruvilu, Guirivilu, Guirivilo, etc., (from Mapudungun: ngürü, "fox" and Mapudungun: filu, "snake";) is a creature originating from the Mapuche religion of the indigenous people inhabiting Chile. It is a lake- or river-dwelling creature that appears in the form with a fox-like head and snake-like body (or a cat-like head with a slender fox-like body and serpent-like tail), which snatches wading people with its (clawed) long tail, and devours or blood-sucks its victim.
