Comments: North Pacific: eats fishes, krill, calanoid copepods, squid. North Atlantic: primary foods are fishes (e.g., capelin, herring, sand launce), krill, and calanoid copepods. Southern ocean: main diet is krill. Gulf of California: eats euphausiids in winter and spring (Tershy 1992). Newly weaned young eat crustaceans; fine fringing on baleen of young facilitates capture of copepods.
