The walrus is a large seal-like aquatic mammal known to be native to Northrend. They are believed to live as far north as Icecrown Glacier. Tuskarr are described as looking like walrus-men. Bull walruses are often hunted by Ursa Totemics, and they can feed two or three hungry furbolgs. A few penguins, walruses, and other arctic sea creatures might use Icecrown Glacier's shore as a resting place.
