Found in coastal waters of the continental shelf and slope (Ref. 1394); and whelp in groups on beaches, sandbars, and rocky reefs (Ref. 1522). Feeds on a wide variety of fish, cephalopods, and crustaceans of surface, mid-water and benthic habitats (Ref. 1394). It is preyed upon by the great white shark (Ref. 32140). Found in coastal waters of the continental shelf and slope (Ref. 1394); and whelp in groups on beaches, sandbars, and rocky reefs (Ref. 1522). Also for resting, moulting and lactation during low tides. Typically perform U-shaped dives. Leave the coast on foraging trips to deeper offshore waters where prey is abundant (Ref. 96347). Feeds on a wide variety of fish, cephalopods, and crustaceans of surface, mid-water and benthic habitats (Ref. 1394).
