White Hawaiian Pleurobranch?

From: Keoki Stender

Hi Bill,

Here's a tiny white slug from a tidepool on the SW tip of Lana'i, Hawaii. Is this Berthella stellata?

Locality: Kaunolu Bay tidepool, SW tip of Lana'i Island, Hawaii, USA. Depth: 0.5 m. Length: 7 mm. 23 March 2003. shallow tidepool with sparse algal turf, boulders, and red silt. Photographer: Keoki Stender

Thanks,

Dear Keoki,
The blue spots on this animal, which seem to have a ligher ring around each spot, look very like the blue 'eye spots' found in some Sea Hares, such as Stylocheilus striatus and Bursatella leachii. I think you photos show a juvenile S. striatus lying on its side, with us looking at the sole of its foot. At the right end of the photo is what I think is the head, the enrolled tentacle you can see, rather than being the enrolled rhinophore of a pleurobranch is the oral tentacle of a Sea Hare. I don't know any pleurobranch with blue spots like this, and B. stellata usually has some sign of an opaque white cross on the mantle. The absence of  dark lines sometimes occurs in juveniles, but the fact that it lying on its side suggests it is dead or dying and so some of the outer colouration may have gone.

Of course I may be quite wrong - its a bit hard with a photo. If I had a specimen I could roll it over or give it a gentle poke and prod. 
Best wishes,
Bill Rudman
