Main Ref. Jefferson, T.A., S. Leatherwood and M.A. Webber, 1993
Remarks 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).
