| Remarks | Secwépemc word for "having a bloody mouth". According to a story entitled, "The War with the Sky People" (Ref. 10944), fishes descended from the upper world. Those who tried to throw themselves into a large lake were wounded because in their fall, some missed the lake and dropped on rocks. That is why the redmouth sucker has a bloody mouth. |
