Hi Jackie,

Interesting submission, but puzzling too. The dorids look a bit shiny for Rostanga which is usually covered with caryophllidia, but maybe these two have secreted slime. The other puzzle is that the two eggs ribbons are quite different morphologically, suggesting that could from different species. The second, whitish ribbon appears to be a wide ribbon attached on edge, whereas the more classical Rostanga ribbon is tighter and flat. I guess we will never know.

Best wishes,
Dave Behrens
