Jaw of a walrus
Detailed Description
The lower jawbone of an adult male walrus rests on the sandy shore of St. Matthew Island, Alaska. The Pacific Walrus (Odobenus rosmarus) is a large pinniped that occurs within the Bering and Chukchi Sea regions. Although more commonly observed on the mainland coast of western Alaska, walrus "haulouts" have been observed on St. Matthew and nearby Hall Island.
