Yesterday we have found, what we believe is a new species of Nudi for the Netherlands (number 46, our nudi list is still not so very big). I have enclosed a digital image from a video recording. The quality is not so good but I am working on slides that should be available by the end of this week.
I believe it is a Eubranchus species. It is not likely to be of any help, but at the moment I only have the following information:
It was found on a species of seaweed.
At approx. 5 meters depth.
It is approx. 12 mm in length.
This message was also send to Michael Miller and other nudi experts. So far we have no idea what it is! Can you help???
I am still working on completing the Dutch list for the Forum. But I can find little time to do so. Perhaps I am just diving too much. Sorry for the delay.
With best regards

I think this is probably a sacoglossan rather than a nudibranch. There only seem to be one set of obvious head tentacles, and they seem to be enrolled. At a guess I would say it is probably Hermaea bifida (Montagu, 1815), which is usually found on red algae. According to various authors (see Thompson, 1976) it has a strange smell likened to a Geranium plant, and sulphuric acid.
But perhaps I should wait until you can send some slides.
