In mythology of Andean civilizations of South America, the amaru or katari (aymara) is a mythical serpent or dragon.

In Inca mythology, Amaru is a huge double-headed serpent that dwells underground, at the bottom of lakes and rivers.

[1] Illustrated with the heads of a bird and a puma, Amaru can be seen emerging from a central element in the center of a stepped mountain or pyramid motif in the Gateway of the Sun at Tiwanaku, Bolivia.

[4] Thus the deity Amaru symbolizes the water that runs through the irrigation canals, rivers and springs and that makes it possible for the seeds of the crop to be transformed into vegetables.

[4] The two Amarus tried to fight the gods but then they tried to escape flying to the skies, but Wayra drag them back to earth with the power of wind and Illapa fought and put the final blow to them.
