Shelled veliger of Facelina bilineata PHOTO: Yoshi Hirano.
This is one of a series of photos Yoshi Hirano has sent me illustrating larval development in two species of Facelina in Japan. I have put this photo up to illustrate my answer to Jennifer's message below. When I return from Menfi I will have time to put up all of Yoshi's photos.Authorship details
