After comparing this animal [message #15178] with my earlier message [#6481], I think you are right that this is Aldisa cooperi. The description that I have states that Rostanga pulchra may have brown or black specks, hence the confusion. I have a question regarding the "bumps" that characterise many dorids from British Columbia. What are caryophyllidia tubercles as opposed to "regular" tubercles, and can we tell the difference from a photograph?

I had forgotten you earlier photo of Aldisa cooperi. If you have photos of Aldisa cooperi and its egg ribbon, and Rostanga pulchra - from shallower water -, and its egg ribbon, they would be nice to have for comparison.
Concerning caryophyllidia. Have a look at the photos of Rostanga orientalis and R. calumus on their Fact Sheets, as they show the 'furry' appearance of animals with caryophyllidia very well. A close-up can be seen on the Fact Sheet for Jorunna pardus. Caryophillida are papillae with a circlet of sharp spicules around the tip. The caryophyllidia are usually packed close together so you can't see the mantle surface, unlike the two Aldisa species, where the tubercles are relatively sparse, and the mantle slin clearly visible.
