Berthellina edwardsi

(Vayssière, 1896)

Nadia Chiesi Numana - Adriatic sea - Italy (The Italians Lembeh ) Berthellina Edwardsii Dive Site : Nicole

Eric van Andel Today at Oosterschelde; St Annaland. Found a Aeolidia papillosa that has a orange like color (especcialy the tips of the rinophores). Perhaps getting in the mood for the European Championships Soccer as a fan of the Dutch team??

João Pedro Silva I wonder what you would say about the Doriopsilla or Armina maculata and of course Berthellina edwardsi. Actually, orange is a very common colour in our opistobranchs. I wonder if someone has ever tried to find patterns in the geographic distribution of colour.

Eric van Andel Here in NL you only see white or brownish Aeolidia papillosa that was why I was wondered... Is it Ecotypical Variation?? With other words... do they get the color of the food they eat?

João Pedro Silva I'm really not sure. Some do get their colour from the food (or what we actually see is the colour of the food), even showing some variation along the digestive gland (http://www.flickr.com/photos/jpsilva1971/4784556408/). But what to say about Cratena peregrina's "war paint"? http://www.flickr.com/photos/jpsilva1971/5830432341/

Marco Faasse João, that's an interesting splanchnotrophid parasite in your Cratena photo, any idea which species it belongs to?

João Pedro Silva Marco, I have no idea. But I've been tagging the photos with parasites and assembling a set on Flickr: http://www.flickr.com/photos/jpsilva1971/sets/72157626974078442/

Marco Faasse Very good! There are several species of splanchnotrophids in the NE Atlantic. I noticed that some egg sacs are white and others are purple. I wonder whether different parasites produce eggs in different colours. We have Spanchnotrophus angulatus parasites with purplish eggs in Aeolidiella glauca.

David Kipling Probably will only see these on a dive if you're shallow and turn rocks over.

Cynthia D. Trowbridge I have seen them intertidally under rocks in Ireland (Lough Hyne)

Tony Gilbert Great Berthella shot.

Tony Gilbert I've yet to spot the eggs, very similar to other species in size/shape colouration. If the Pleurobranch wasn't there I'd be mistaken in thinking the eggs were either Hypselodoris or Archidoris. In Lanzarote Canaries, there are also Berthella species, namely B. edwardsi, although I think B.plumula may also be present. http://www.flickr.com/photos/tonyjgilbert-images/7164315073/in/photostream Like yourself, as soon as light is thrown upon them they are quickly off into darkness. So, we only see them during night dives in the darkest of hidden places like caves.

João Pedro Silva I've never seen the eggs of Berthella plumula nor B. stellata, which I suppose have similarly shaped egg masses. Those of Berthellina edwardsii are quite different from those in David's photo: http://www.flickr.com/photos/jpsilva1971/5718907181/

Craig De Wit Ok nudilovers.. help needed!!! :-) I have a 14 year old niece who is doing a school project on nudibranchs and she needs support with video footage or such.. would any of you be able to assist? She lives in Brisbane and I am currently out on charter in Milne Bay so cant help her...SOS Craig.

Kristin Anderson Photos I have accessible but all my video isn't Pm if it will help

Craig De Wit Kristin... that may help too.. thanks..will get back to you! :-)

Terry Farr I have a few videos I am happy to give but the quality from this site is much better than anything I have http://slugsite.tierranet.com/

Craig De Wit Thanks for your input Terry Farr..will get her to check and get back to you

Karen Enayati Here you have one of ours video from South Spain. The footage of Hypselodoris picta is quite short, but maybe it is useful. Also to be seen some Nudi eggs ribbons, Aplysia depilans and some lovely Aplysia fasciata swimming. http://www.youtube.com/watch?v=NHnurhWsayY&feature=channel&list=UL

Craig De Wit Thank you very much Karen!!! Wish I could look at it myself however I have very slow interent here. Will pass you comment onto my neice.. again many thanks.

Gary Cobb Talk to Mike Miller of the Slug Site

João Pedro Silva Karen Kienberger, loved the video as it illustrates some of the species we also find here in Portugal. The eggs appearing after the Hypselodoris picta are from Berthellina sp. (most probably Berthellina edwardsii) and not from a nudibranch.

João Pedro Silva Craig De Wit, I don't shoot video but my photos of nudibranchs are here: http://www.flickr.com/photos/jpsilva1971/collections/72157627467298556/

Karen Enayati Thanks João Pedro Silva for the information. Yes, it could be a Berthelina edwardsii, as they are some in this zone. And I am pleased to here, that you liked our video.
