Erling Svensen Anybody that knows these eggs? On a red algae - 10 meters dept, in the harbour of Egersund.

Wilfried Bay-Nouailhat Eggs of Aplysia cf. punctata

Erling Svensen Thanks. Never seen them before.

Bernard Picton You're being cautious there Wilfried, or do you suspect that Aplysia punctata is not a single species in our area? In France you should also have Aplysia fasciata and Aplysia depilans, but in Norway I think just the one Aplysia species. Are the other Aplysia spawn masses any different to these?

Wilfried Bay-Nouailhat Hi Bernard. ALong with the tiny A. parvula, we have 4 Aplysia species in Brittany but I'd prefered be cautious because I didn't check if there were several Aplysia in Norway. Concerning the spawn of the 3 largest ones, all I can say is that more or less compact masses can be seen, maybe depending on the species. As for the colour, eggs of A. depilans and A. fasciata can be white, yellowish or pink or the three colours in the same mass.

Alexander Niedermair Aplysia depilans ? Selce - Kroatia

Bernard Picton I'm pretty sure this is Aplysia punctata, looks just like our ones in UK.

Sylvie Omnès I think Bernard's id is the one !

Athos Mastropierro

Ron Silver Aplysia depilans?

Athos Mastropierro yessssss ;-)

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.

João Pedro Silva These may be common but extremely hard to find. That is if you're not willing to take a few sea hare egg masses home, put them on a tray and wait for the nudibranchs to come out. I like things done the hard way so I just look for them and expect to get lucky.

Christian Skauge Technically, sea hares are not really nudibranchs ;-)

João Pedro Silva I know, Christian. Maybe the text was not clear: Favorinus branchialis (a nudibranch) feeds on opistobranch eggs (but also hydroids). Due to their size, the egg masses from sea hares (especially Aplysia depilans and Aplysia fasciata) is more likely to contain Favorinus branchialis. As it's very difficult to find this species, the easiest way is to collect eggs masses from Aplysia sp., bring them home (or to a lab), place them on a tray and wait for the Favorinus branchialis to appear.

Christian Skauge Ahh, sorry, I didnt' catch your meaning! of course you'll get the F. branchialis with the sea hare eggs - that's what they eat! We see the same with F. blianus and A. punctata in Norway. Thanks João :-)

Christian Skauge We do even get the F. branchialis here north - very rare, but sometimes :)

João Pedro Silva I must have seen it no more than ten times, but I never tried collecting sea hare's eggs. I simply found them crawling on the bottom.

Christian Skauge Me neither - that's just too nerdy ha ha :-)
