The Nguruvilu "fox snake" (also: Guirivilo, Guruvilu, Ñuruvilu, Ñirivilu, Ñivivilu, Ñirivilo o Nirivilo; from Mapudungun ngürü "fox" and filu "snake") is a creature found in the Mapuche religion of Chile.
The serpopard is a mythical animal known from ancient Egyptian and Mesopotamian art. The word "serpopard" is a modern coinage. It is a portmanteau of "serpent" and "leopard", derived from the interpretation that the creature represents an animal with the body of a leopard and the long neck and head of a serpent. However, they have also been interpreted as "serpent-necked lions". There is no known name for the creature in any ancient texts.
