Aeolidia papillosa vs Flabellina salmonacea

January 29, 2004
From: Mary Jo Adams

Hi,
We commonly find Aeolidia papillosa at Rosario Beach (Fidalgo Island, Washington, USA). We spotted this 2 inch nudibranch last week and it looked different as the cerata did not cover the anterior tip of the nudibranch. Looking it up, we thought it might be Flabellina salmonacea but weren't sure. Can you tell from the photo which species it is?
Thank you.
Mary Jo

Dear Mary Jo,
From the general shape of the body - very broad with numerous rows of cerata - make me certain that this is Aeolidia. If you look at other photos of Aeolidia papillosa in the attached messages you will see that the cerata don't always cover the front of the animal.
Best wishes
