The bowhead, Arctic, or Greenland whale (Balaena mysticetus), from whose mouth the best whalebone is obtained.
Large marine mammals of the order Cetacea. In the past, they were commercially valued for whale oil, for their flesh as human food and in animal feed and fertilizer, and for baleen. The sperm whale produces AMBERGRIS, an intestinal secretion used in perfumery. (From Webster, 3d ed)
