Steller Sea Lions (Eumetopias jubatus)

Steller sea lions (Eumetopias jubatus) range along the north Pacific rim from northern Japan to California. Pupping and breeding occur late May to early July throughout their range. Males set up territories on rookeries in late May; females arrive shortly thereafter and give birth to a single pup. A mother alternates between nursing her pup and feeding trips; most pups are weaned by the end of their first year. The species is not known to migrate, but individuals disperse widely outside of the breeding season, particularly adult males and juveniles.

Two separate stocks of Steller sea lions are recognized within U. S. waters: an eastern and western stock. The increasing eastern population segment, in southeast Alaska, British Columbia, and down the West Coast into California, is listed under the Endangered Species Act (ESA) as threatened.

NOAA Fisheries' Alaska Region manages Steller sea lions. The Alaska Fisheries Science Center's Marine Mammal Laboratory does research on Steller sea lions. These animals occur in the Northwest Region, so ESA critical habitat is designated in some areas. See the links to the left for more details.
