Limenandra sp. 2
Order: NUDIBRANCHIA
Suborder: AEOLIDINA
Family: Aeolidiidae
DISTRIBUTION
Known only from Colombia
Almost certainly a member of the Family Aeolidiiddae it is tentatively considered a Limenandra because of its general shape and the description below of its rhythmically waving cerata.

Limenandra? from Colombia
October 6, 2001

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.

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,

Funny nudibranch from Colombia
June 3, 2001
From: Elianny Domínguez
Dear Bill,
This is the first nudibranch I´ve seen that can move it´s cerata constantly from left to right, like a little clock machine.
We found it under a rock without any fauna or flora associated (supralitoral), and has 3cm of lenght. [found on rocky bottom, Bay of Chengue, Tayrona National Park, Santa Marta, Colombia - Caribbean coast]
Do you have any information on this behavior?
Or the species?
Kind regards,
Elianny Domínguez.

Domínguez, E., 2001 (Jun 3) Funny nudibranch from Colombia. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/4426Dear Elianny,
This is almost certainly Limenandra nodosa which is also found in the Indo-West Pacific. I can't see the characteristic rings on the back in your photo. Have a look at my photos at the top of the page. Did your animal look like that? I am glad to read of your description of the cerata moving like clockwork. As I have described at the top of the page this is to me the most fascinating character of this species. Whenever I see it jerking along as it waves its cerata in unison I have to call people over and show them. I don't know why it does it, I don't know why no-one else has mentioned this behaviour in publications, but it certainly links your animal from the Carribbean with the ones I have seen in the Indian and Pacific Oceans.
Best wishes,
Bill Rudman
