Dear Bill,
I have attached an image of an anemone I have found on several occasions in the Brunswick River. It is difficult to tell from Jose's picture but the protuberences on the exterior resemble those on this image. I believe it is an Alicia sp but I have only seen images on the web so I can't confirm this as I know very little about anemones.

Cheers
Denis

Dear Denis,

Thanks for the suggestion. The anemones of the family Aliciidae do have compound vesicles like this, full of stinging cells, on the outside of the column. No wonder I couldn't get a clear count for what I thought were the retracted tentacles of a cluster of polyps.

For those who are wondering about the anemone's orientation in Dennis's photo, the anemone is unattached and the attachment disc is at the bottom right corner of the photo. It's nice to get a pretty reliable identification for this aeolid's food, even if we haven't got a name for it. It certainly suggests that it belongs to the family Aeolidiidae.

Best wishes,
Bill Rudman

Unidentified aeolidiid again

We found this slug at Dos Palmas Resort, Honday Bay, Puerto Princesa, Palawan, Philippines. Three of them found at depth of 30-40 ft feeding on an Anemone as shown in the pictures.

Dear Jovic,

This is a nudibranch I have been calling Unknown aeolidiid sp 2 because I am pretty sure from its shape that it belongs to the family Aeolidiidae, but I am also pretty sure it is unnamed.

I am interested in your photo of it feeding. Have you a better photo of the 'anemone' it is on. Why I ask is that its shape looks more like a soft coral than a sea anemone, and when I try and count the number of tentacles on each polyp there seem to be eight, which would make it a soft coral, rather than six, which sea anemones have. It may not seem important to know which, but species of the aeolidiidae usually feed on sea anemones so it would be most unusual to find one on a soft coral

Best wishes,

Dear Dr Rudman,

I'm happy to send you a new pic of this "Mystery slug". A friend (Olivier Julien, Bourail Sud Loisir) has seen it one time in Bourail (New-Caledonia west coast). I'm pretty sure that it's the same as Constantinos Petrinos's photo.

Locality: Bourail, 15 m, New Caledonia, Pacific ocean, 12 December 2007, Sand. Length: 30 mm. Photographer: Olivier Julien.

Thank You

Dear Jean-François,

Thanks for another record of this aeolid. All we need now is someone to have a look at its anatomy so we can decide what it is related to.

Bourail, where it was photographed is a beautiful part of New Caledonia - one of Risbec's collecting spots - and it even has its own slug, Phidiana bourailli.

Bill Rudman

Hi All:

Please look at Mike Miller's "Branch of the Week No. 486" 

This beautiful critter has been observed several times now.

Thanks Dave,

It certainly is a spectacular animal. Have you any idea what the hair-like strands are that it is crawling on? They look like very thin sea anemone tentacles but the aeolid doesn't seem at all concerned. I think this species deserves a page of its own.

Dear Bill and Ken,
This reminds me of Spurilla australis, or the S. major you identified for Takako and Stephen in message #9201.

Just a thought.

Thanks Phil,
Many of the Aeolidiidae have this sort of 'look'. What make this animal so distinctive is the very elongate body and the yellow transverse bands on the foot. Bands on the foot like this remind me of Cerberilla ambonensis, which it clearly is not, but I can't recall another aeolid with similar bands.

Limenandra ? from Indonesia

June 15, 2007
From: Ken Tucker

This photo was taken in the Lembeh Strait, North Sulawesi, Indonesia. Dive site is known as Hairball, and photo was taken 25 Nov 2006. Unrecorded depth, perhaps 6 cm.

The resident dive guide says he has not seen before, other than my photos [approx 45]. Debelius has a photo of Limenandra nodosa, brown/cream, from Western Australia. Primary similarity to my photo is the large somewhat circular back pattern.

Locality: Lembeh Strait, Indonesia, 25 Nov 2006. Length: 6 cm. Photographer: Ken Tucker.

Dear Ken,
This certainly looks like an aeolidiid of some sort although in Limenandra the ceratal rows are usually arranged in pairs. In length it reminds me of Pteraeolidia ianthina and in the way the base of the rhinophores are fused it reminds me of a species of Babakina. On balance I think it is a member of the Aeolidiidae, but I can't say much more.
