Re: Flabellina pedata? from Spain

Hi Bill,

I'm currently spending a short visit to the Chris Todd's lab in Scotland. Nevertheless, I'm checking the Sea Slug Forum.

Concerning Erwin's "Flabellina pedata", it seems to me that is probably an unknown species. According to my knowledge, and considering the size of the specimen, the digestive gland is not visible in F. pedata, since all the surface of the cerata are violet coloured, except an subapical opaque white ring. This is not the situation with Erwin's animal. The other violet Mediterranean Flabellina are F. affinis and F. ischitana. You can see the ceratal digestive gland in these species but they have a different arrangement of the cerata in the anterior groups (they are pedunculate).

It would be necessary to examine the internal anatomy to confirm my suspicion that this is an unnamed species.

Once again, the colour pattern is not enough to determine whether a species is unknown or a variation of a known species.

Dear Lucas,
Thanks for your comments, and give my regards to Chris. It would be nice to have some information on the Forum about the interesting work Chris and his team are doing on opisthobranch ecology.

Best wishes,
Bill Rudman.
