Dr. Rudman -
I thought you might like this image of Berthella strongi - it shows the texture of it's skin. I came across the slug at San Miguel Island, California, at about 35ft.

Thanks Ken,
One of the main external differences between this and Berthella californica is that this species has a smooth mantle while in B. californica the larger white spots are on raised tubercles. The smooth nature of the skin can be seen clearly in your photos.

The presence of sea anemones in the photo make me wonder just what this species eats. Dave Behrens (1980) reports it being associated with compound ascidians, which may well be its food, but I don't know of any sightings of it actually feeding
Best wishes
