An amarok, or amaroq, is a gigantic gray wolf in Inuit mythology, said to stalk and devour any person foolish enough to hunt alone at night. Unlike real wolves who hunt in packs, amaroks hunt alone.
Writing in the 19th century, Danish geologist and Greenlandic scholar Hinrich Johannes Rink reported that the Greenlandic Inuit reserve the word amarok exclusively for this legendary wolf, whereas other Arctic peoples use it to refer to any wolf.
