Distributed from the tropics to the ice edges in both hemispheres. They can be seen offshore, and more often in coastal and inshore areas. They are rarely seen in some tropical pelagic areas. Minimum depth from the Pacific (Ref. 83490) and maximum depth based from their food in the Atlantic (Ref. 83488). Feeds on krill and small schooling fishes (Ref. 1394). Oceanodromous (Ref. 75906). Distributed from the tropics to the ice edges in both hemispheres. They can be seen offshore, and more often in coastal and inshore areas. They are rarely seen in some tropical pelagic areas (Ref. 1394). They are known to be 'gulpers,' feeding in separate events, often lunging at large schools of fish (Ref. 122680). Also feeds on krill (Ref. 1394). Oceanodromous (Ref. 75906). Also in Ref. 75805 (Ref. 75906).
