About the Steller Sea Lion#
The Steller sea lion (Eumetopias jubatus), also known as the northern sea lion and Steller's sea lion, is a near-threatened species of sea lion in the northern Pacific. It is the sole member of the genus Eumetopias and the largest of the eared seals (Otariidae) and is also the largest species of sea lion. Among pinnipeds, it is inferior in size only to the walrus and the two species of elephant seals.

Field-craft tips#
- Harbours and piers give close but legal views.
- Boat motion adds blur — keep 1/1000 s minimum and use stabilisation.
- Sightings peak in June, July and August, which is when you'll have the most chances.
Ethics#
- The welfare of the animal comes first: if it changes its behaviour because of you, you are too close.
- Stay on trails, respect closures around nests, leks, dens and haul-outs.
- Avoid playback and baiting in sensitive seasons; never bait predators.
- Don't share precise locations of rare, nesting or roosting animals publicly.
