Limenandra? from Colombia

October 6, 2001
From: Elianny Dominguez

Dear Bill,
Here are some close-up photos of the 'funny nudibranch'. You can see the shape of the cerata and the rhinophores.

We don't think it is Limenandra nodosa and have sent separately photos of what we think is Limenandra nodosa. The 'funny nudibranch' didn't have any kind of circles. The cerates are arranged just like in Austraeolis ornata and Austraeolis catina. The cerata form little crowns (in the dorsal region) with longer cerates towards the head of the animal. The crowns are smaller and with shorter cerates towards the posterior end of the body. The color pattern is also similar to the one on Austraeolis ornata, only lighter. I have more pictures but the one I sent you was the clearer one.

Kind regards,
Elianny Dominguez.

Dear Elianny,
Thanks for the photos of what you think is Limenandra nodosa. The rings you describe on the back are certainly characteristic of that species. Which leaves this species, which I originally thought might be Limenandra nodosa because of your description of the cerata moving like 'clockwork', as a bit of a mystery.

All I can say is that it is probably in the family Aeolidiidae and is possibly a species of Limenandra, but that is only a guess.
Best wishes,
Bill Rudman
