St Brides Haven, St Brides Bay, Pembrokeshire; 5m depth
3m depth - I don't find them this shallow diving my usual spots in Cape Ann
A few tucked in among the Astrangia. Shallow ≈3m. Unusual to see these on a shallow shore dive in my area (northshore MA). Another observation from this location here: https://www.inaturalist.org/observations/146757999
