Limenandra nodosa from Caribbean

From: Linda Ianniello

Hi, Dr. Bill,
Here is another unknown from the Caribbean. It was found in a depth of about 12', during the day, in sand and rubble off the coast of Deerfield Beach, Florida. It was very small, about 1/2 inch. I am sorry, the pictures are not very clear and it is tough to see the identifying features except for the red rings down its back, which I hope will be a clue. I can't find anything like it in my Caribbean references. As usual, thanks very much for your help and the forum is an excellent source of information!
Linda I.

Dear Linda,
The red rings are indeed a distinguishing feature for this species. There are usually a pair of concentric rings, usually red and yellow, and sometimes a central red spot as well. This is Limenandra nodosa, an interesting aeolid with its cerata arranged in double rows. As you will see from my other comments on this page, it has a unique way of 'jerking' its cerata as it crawls along.
Best wishes,
Bill Rudman
