In Inuit mythology, the Tizheruk is a mythical large snake-like creature that is said to inhabit the waters near Key Island, Alaska. This legend was first started by the Inuit. It is said to have a 7-foot head and a tail with a flipper. The local natives claim that it has snatched people off piers without their noticing its presence. It is also called Pal-Rai-Yûk. It is said to be similar to Naitaka of the Okanakanes (Ogopogo) and the Haietlik of the Nootka.
