The body is translucent clear. The cerata have a broad orange to yellow terminal band, the cerata some times being tipped with white. The upper half of the lamellate rhinophores are also yellowish orange, sometimes with a white tip. Both the oral tentacles and the tentacular anterior foot corners have and orange midregion and a white tip. The oral tentacles also have a white or cream line which runs along the dorsal side and then across the head to the base of the rhnophores. Sometimes parts of this line, on the head, have red, orange or yellow pigmentation. Grows to about 25mm.

If I look very carefully I think I can see a trace of a whitish/orange line running from the oral tentacles back to the first cerata. The line seems to be characteristic of this species.

I've been in withdrawal for the past three weeks and am eagerly anticipating the return of my daily slug fix!
FYI: In Dave Behrens' newest book on Eastern Pacific Nudibranchs, he lists Facelina stearnsi as Austraeolis stearnsi (Cockerell, 1901). The fact sheet for this branch should be updated with the new (old?) name.
Glad to know that your mornings will be calm again - I hope you aren't one of those people who kicks the dog when things go wrong! Concerning Facelina stearnsi. I had noticed Austraeolis starting to creep in but I could find no published reference and after checking with Dave Behrens I find the relevant paper - from the Perth conference is still 'in press'. So at present there is no published evidence to support the genus change. I guess I should keep the status quo until I get a chance to read - and agree with - the arguments presented by the authors.

Roger Carlson spotted this nudibranch that we have tentatively identified as Facelina stearnsi based on the description in Behrens (2nd Edition). The branch was found on the bow of the wreck of the Avalon, off Palos Verdes, Southern California. The depth was 70 feet and the temperature was in the low fifies. This was the only individual that we found. We did not see any egg masses.

Here is another California species that is absent from the Forum, Facelina stearnsi. These animals were photographed on the wreck of the El Ray off Mission Bay in San Diego.
