Haietlik
A mythical water serpent of the Nootka, the name Haietlik means Lightning Snake.
According to the legend, the Lightning Snakes were sent off by the Thunderbirds to kill orcas for food. Once he saw a whale, Haietlik attacked it. Haietlik's head was as sharp as a knife and its tongue shot lightning bolts. This would injure the whale enough for Haietlik to carry it as prey.
The Canadian Forces 442 Transport and Rescue Squadron badge features Haietlik.
