According to folk beliefs from Shetland Islands, Wulver is a creature in the form of a man with wolf’s head and a body covered in short brown hair. A formidable-looking but harmless and even benevolent creature described by Jessie Saxby in "Shetland Traditional Lore":

The Wulver was a creature like a man with a wolf's head. He had short brown hair all over him. His home was a cave dug out of the side of a steep knowe, half-way up a hill. He didn't molest folk if folk didn't molest him. He was fond of fishing, and had a small rock in the deep water which is known to this day as the "Wulver's Stane". There he would sit fishing sillaks and piltaks for hour after hour. He was reported to have frequently left a few fish on the window-sill of some poor body (1457: Ch.9; 1290: p.445-446).
