The Steller sea lion, Eumetopias jubatus, also known as the Northern Sea Lion, is a sea lion of the northern Pacific. It is the sole member of the genus Eumetopias and the largest of the eared seals (Otariidae). Among pinnipeds, it is inferior in size only to the walrus and the elephant seal. The species is named for the naturalist Georg Wilhelm Steller who first described them in 1741. The Steller sea lion has attracted considerable attention in recent decades due to significant, unexplained declines in their numbers over a large portion of their range in Alaska.
