Remarks	Found in shallow water, most often nearshore, although they occasionally travel over deeper offshore waters (Ref. 1394). Uses echo-location for orientation and foraging by emitting high frequency click sounds (Ref. 96345). Feeds on a wide variety of fish and cephalopods; small, non-spiny schooling fish (such as herring and mackerel) (Ref. 1394).
