Steller Sea Lion Range and Rookeries

map of Steller sea lion range

Steller sea lions (Eumetopias jubatus) live in the North Pacific Ocean and consist of two distinct populations separated at 144 W longitude (near Cape Suckling, just east of Prince William Sound, Alaska). The National Marine Fisheries Service listed the Steller sea lion as threatened rangewide under the Endangered Species Act in April 1990. The decline has continued for the western population in Alaska, which was declared endangered in 1997. The eastern population remains listed as threatened.  (Return to Steller Overview
