Concerning message #21026:

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.

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
