Flabellina borealis

Jørn Ari OLYMPUS E-420 Jorn Ari

Jim Anderson Looks like Flabellina verrucosa to me.

Bernard Picton The broad white bands at the tips of the cerata are more typical of Flabellina browni. The rhinophores and oral tentacles both look robust. We must not forget Flabellina borealis in your region; as far as I know it has not been photographed, but looks a bit like this.

Bernard Picton How big was it, Jorn?

Jørn Ari I guess it´s 15-20 mm Its two years ago and before I started recording my observations.

Jørn Ari Can anyone help me finding information and pictures of Flabellina borealis? I have searched the net but haven´t found anything usefull. Best regards Jorn Ari

Christian Skauge Try searching for 'coryphella borealis' ;-)

Bernard Picton Jorn, I think there is just the original description. A belgian girl dredged some in the North Sea, lots of them, but they were preserved when I got them and I identified them from the radula. I suspect that we will easily mistake them for another of the Flabellina in the area and could be misidentifying them.

Christian Skauge Interesting, I wonder if we can find any at the Nudibranch Safari ;-)

Jørn Ari @ Christian. I did try with coryphella, but same same. We have to find some in Gulen..

Christian Skauge I think we do! I searched a bit too, it roused my interest - but alas, nothing.

Bernard Picton This seems to be the original description, but I think there may be a later reference with a drawing of the radula. I'll certainly check that next week when I'm back at work... http://www.biodiversitylibrary.org/item/109307#page/39/mode/1up

Christian Skauge It seems to have been found in many places all along the Norwegian coast?

Jørn Ari Thanks guys
