Númhyalikyu, “one chief one”, is an enormous, monstrous halibut of Pacific Northwest Kwakwaka’wakw folklore. Its back looks like a beach, complete with ripples left behind by the waves. It has the head of a seal, with a shining spot that gleams like fire.
If a númhyalikyu is killed, its head can be stabbed and its gleaming ornament extracted, revealing it to be a hard and shiny crystalline object. This is known as tlúgwi, and it is highly valuable. It is hard to pinpoint the location of a númhyalikyu, however, as it makes a deep humming sound that reverberates through water and air and rumbles through the trees, seeming to come from everywhere at once.
Númhyalikyu brings bad weather and storms. When it comes to the surface, it creates treacherous shallows that wreck canoes. Its rippled back, often just below the surface of the water, can be easily mistaken for a small island.
Númhyalikyu’s dance is númkahl, “personification of númhyalikyu”. The initiate playing the part of númhyalikyu wears a face mask, and is caught on the beach after metaphorically leaving the sea.
