Ngalyod (Rainbow Serpent)
Ngalyod (Rainbow Serpent) is a most important ancestor spirit in western Arnhem Land and appears in various manifestations in Kunwinjku mythology. It is believed that as a serpent she tunnels underground using barbed extensions from her head and the bony protuberance from her neck as aids. She is generally feared as she may swallow Aboriginals who break traditional laws. Ngalyod dwells also in various billabongs in Arnhem Land. In the Dreamtime Ngalyod assumed a range of animal forms, including snake, kangaroo and crocodile and at times transformed herself from one to the other, or into a combination of each.
