HERE THERE WERE DRAGONS
As isolated as they are, the Hawaiian Islands share one curious feature with Europe and Asia: all of them have legends of dragons. Like their European and Asian counterparts, Hawaiian dragons are lizard-like, have magical powers, can be good or bad, and often live in caves. Unlike the others, however, Hawaiian dragons do not have wings, do not fly, and do not belch fire. Dragon stories are among the oldest in the islands.
The key word in Hawaiian is mo'o, which can mean a lizard, a reptile of any kind, a water spirit, and even a scorpion. When describing a dragon, the form is usually mo'o nui, meaning "big lizard." Interestingly, mo'o nui is also the word for crocodile. An alternate word for dragon is kiha, which also means "sneeze" and could be translated as "life force." Hawaiian dragons are almost always associated with water, usually near to or in the ocean.
One theory has it that mo'o nui originally referred to saltwater crocodiles. Although there are currently no saltwater crocodiles in Polynesia (nor any snakes, either, for that matter), that may not have always been the case. Saltwater crocodiles normally are found in India and Southeast Asia, but they are known to be able to travel in the ocean for great distances and some have been found outside their normal range as far into the South Pacific as Fiji. Hawaiian historian Samuel Kamakau, writing in the 1800s, said that the guardian mo'o of fishponds were twelve to thirty feet long, which is also the reported size range for saltwater crocodiles.
Nothing related to dragons is simple, however. In Europe, dragons are associated with Druids, and the Druidic religion. In Hawaii, the legends associate dragons with sorcerers, and there were temples dedicated to their worship.
Here are a few kinds of Hawaiian legends about mo'o nui:
Another tale from Kauai in which a beautiful half-dragon half-woman named Palai ("to hide away") lives in the lower wet cave at Ha'ena and lures a local chief into the cave, has a baby by him, kills him, and then disappears into the water of the cave forever when confronted by the local people.
A famous and complicated story from Puna on Big Island about a woman named Laieikawai (difficult to translate, but carries the idea of living in the water) who is raised by a dragon relative called Waka <"serrated, spiky") and guarded by another dragon relative called Kihanuilulumoku ("forest protector dragon").
Kihawahine ("female dragon") is a famous dragon of Maui and Kauai. On Oahu, Laniwahine ("royal or heavenly female") was a prophesying dragon of Waialua, Kanekuaana ("man-carrying one") brought prosperity to Ewa, and Hauwahine ("female to whom one prays") protected the poor and warded off illness in the Ko'olau district, to name a few good dragons. Pi'ikalalau ("the one who goes astray in the mountains") of Kauai, Laniloa ("large royal or heavenly one") of Oahu, and Panaewa ("the famous unjust one") of Big Island were evil ones. Almost all dragons in all legends were female.
Many stories are told about the rivalry and conflict between Pele the volcano goddess, her sister Hi'iaka, and various dragons on the different islands. Some authors consider this as a family rivalry and others as a religious conflict. Perhaps the most famous instance is when Pele has manifested in human form on Kauai to win the affections of the chief Lohiau. During her stay, Pele is challenged by Lohiau's mo'o nui sister, Kilinoe ("misty rain"), to a wind-naming contest which includes the ability to call up each wind named. Pele wins the contest and Kilinoe is later turned into a stone by Hi'iaka. We know the story is true, because you can still see the stone of Kilinoe near Ke'e Beach on Kauai's North Shore.
