Field context

Low intertidal shores and kelp forests, particularly wave-exposed, well-aerated water.

Observing responsibly

Look in rock crevices and pools. Depths describe common viewing habitat, not the species’ full depth range.

When to look

The available records do not establish a reliable local viewing season. Use the map’s month filter to inspect dated observations; it does not predict an encounter.
