From Ainu Folklore
Okikurumi and his henchman Samayungaru went out one day to sea, and speared a large shark, which ran away, up and down the sea, with the line and the boat. The two men grew very tired of pulling at him, and could not prevent the boat from being pulled about in all directions. Their hands were bloody and blistered both on the backs and on the palms, till at last Samayungaru sank dead in the bottom of the boat. At last Okikurumi could hold on no longer, and he cursed the shark, saying: “You bad shark! I will cut the rope. But the tip of the harpoons, made half of iron and half of bone, shall remain sticking in your flesh; and you shall feel in your body the reverberation of the iron and the scraping of the bone; and on your skin shall grow the rasupa-tree and the shiuri-tree of which the spear-handle is made, and the hai-grass by which the tip of the harpoon is tied to the body of it, and the nipesh-tree of which the rope tying the harpoon itself is made, so that, though you are such a mighty fish, you shall not be able to swim in the water; and you shall die, and a last be washed ashore at the river-mouth of Saru; and even the carrier-crows and the dogs and foxes will not eat you, but will only void their feces upon you, and you shall at last rot away on earth.”
The shark laughed, thinking this was merely a human being telling a falsehood. Okikurmui cut the rope, and, after a long time, managed to reach the land. Then he revived Samayunguru, who had been dead. And afterwards the shark died and was washed ashore at the river-mouth of Saru; and the tip of the harpoon made half of iron and half of bone had stuck in its flesh; and it had felt in its body the reverberation of the hammering of the iron and the scraping of the bone; and in its skin were growing the rasupa-tree and the shiuri-tree of which the spear-handle used by Okikurumi was made, and the hai-grass by which the tip of the harpoon was tied to the body of it, and the nipesh-tree of which the rope tying the harpoon itself was made; and even the carrion-crows and the dogs and foxes would not eat the bad shark, and at last he rotted away to earth.
Therefore take warning, oh! Sharks of the present day, lest you die as this shark died!
