A beautiful nudibranch for you -- Colorful Dirona (Dirona picta) photographed by Eric a few days ago. I love the green and blue highlights! [You can click on the image for a larger version.]
P.S. I'm not sure about the meaning of the name Dirona? I read that the first part of the word might refer to the Welsh sêr , or "star," hence the name of this post (but more naming research would be needed!).
