Dear Bill,
I ask your help to identify this nudibranch, photographe last June in the Portuguese west coast (Northeast Atlantic Ocean), in Berlenga Island near the towns Peniche and Baleal, north of Lisbonne.
Locality: Berlenga Island (near Peniche and Baleal), Portugal, NE Atlantic Ocean. Depth: 20 meters. Length: 1,5 cm 25 June 2005. Photographer: Miguel Macedo
Thank You, Best Regards,
Miguel Macedo

Macedo, M, 2005 (Sep 6) Cadlina sp from Portugal. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/14712Dear Miguel,
This is a species of Cadlina. At present only Cadlina laevis is supposed to occur in the NE Atlantic and it usually does not have any yellow markings. But as Bernard Picton and I have discussed [see message #4793] it is possible that there is more than one species involved. As I mentioned earlier, this yellow-bordered animal is probably the 'form' of C. laevis which was reported from southern England to the Mediterranean by Bouchet & Moreteau (1976) who suggest it may be a distinct species. It would be nice to know something about its anatomy and biology, especially what sponge it feeds on and what its eggs look like.
So all I can say is it may be a from of Cadlina laevis, or it may be an unnamed species of Cadlina. We just don't know. There is also a similar problem about what to call the Cadlina on the NW Atlantic coast of North America
