Blackfish is arguably the most important creature in Haida culture. Blackfish is also highly revered in Tlingit culture because of his apparent affinity with humans. He represents an extremely powerful force of nature, deadly and terrifying to every creature except man, whom he is said to look after. The story describes why this is so. There are many variations to the tale, some considerably more brutal than others, and the exact details vary widely according to the storyteller, but the main theme of the story is always the same.
