In Inuit religion, the Tizheruk is a mythical large serpent-like creature that is said to inhabit the waters near Key Island, Alaska.
It is said to have a two-metre (6.6 ft) head and a tail with a flipper.
The local Inuit claim that it has snatched people off piers without their noticing its presence.
It is said to be similar to Naitaka of the Okanakanes (Ogopogo) and the Haietlik of the Nuu-chah-nulth.
