The Steller sea lion (Eumetopias jubatus), also known as Steller's sea lion or the northern sea lion, is a large, near-threatened species of sea lion, predominantly found in the coastal marine habitats of the northeast Pacific Ocean and the Pacific Northwest regions of North America, from north-central California to Oregon, Washington and British Columbia to Alaska. Its range continues across the Northern Pacific and the Aleutian Islands, all the way to Kamchatka, Magadan Oblast, and the Sea of Okhotsk, south to Honshu's northern coastline. It is the sole member of the genus Eumetopias, and the largest of the so-called eared seals (Otariidae). Among pinnipeds, only the walrus and the two species of elephant seal are bigger. The species is named for the naturalist and explorer Georg Wilhelm Steller, who first described them in 1741. Steller sea lions have attracted considerable attention in recent decades, both from scientists and the general public, due to significant (and largely unexplained) declines in their numbers over an extensive portion of their northern range, notably in Alaska.
Adult animals are lighter in color than most sea lions, ranging from pale yellow... Wikipedia →

Rare
Under 5% of wildlife watchers report a Northern Sea Lion sighting in San Francisco on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 31st most-seen of the 38 mammals we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Northern Sea Lion in San Francisco on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Northern Sea Lion sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Northern Sea Lion sightings, San Francisco ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Seattle (United States, under 5%), Portland (United States, under 5%) and Vancouver (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Northern Sea Lion is recorded against all the mammals logged in San Francisco (13 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
