The sisiutl is a legendary creature found in many cultures of the Indigenous peoples of the Pacific Northwest Coast, notably the Kwakwakaʼwakw.
The Tlingit "grubworm" or "woodworm" (caterpillar) is a "peculiarly northern" variation that lacks the central head, and has an insatiable appetite.
[2] The sisiutl also sometimes takes the form of a canoe, as in a myth where it returns a woman from Qomoqua's spiritual realm to her home village, or a squirrel.
Warriors similarly believed that its blood would make them invincible in battle, and they would often accessorize their cultural garb with images of the sisiutl for this magical protection.
For some tribes, the beach mineral mica was believed to be the scales of the sisiutl, and as such would be incorporated into these aforementioned traditions accordingly.
