Concerning message #16336:

Dear Bill and David,
In this animal the rhinophores are plain blue, so it couldn't be H. bilineata (nor H. cantabrica ).

According to the mantle and foot pattern and hidden gills, I think this animal is Hypselodoris tricolor. H. tricolor is more sensible than other blue dorid species. At any disturbance, it tends to hide its gills and sometimes it takes up to 5 minutes to see the gills again. Of course, it doesn't mean all blue dorids with hidden gills are H. tricolor, but it could be an additional clue...

Best regards,
Marina.

Thanks Marina,
Familiarity with local populations often gives us valuable little behavioural clues like this.
Best wishes,
