Morten Bjørn Larsen When I showed this photo to some non diving friends, they asked if a nudi gets blinded or annoyed by the flash... Do they?
Jongrak Lee They have rhinophores, a sensory organ which is shaped like antena, instead of eyes... they're stimulated both by chemicals n physical touches.
Jongrak Lee With my experience, it seems that they get more relaxed n better narcotized in dark conditions.
João Pedro Silva But they do have eyes (visible in this photo at the base of the left rhinophore). Of course, sight is not their best developed sense and I don't think they see images and in most cases aren't even capable of determine the direction of the light.
João Pedro Silva Some do more than others... and it also depends on what they're doing (simply crawling, "sniffing", spawning, feeding, mating...). There's one particular case which puzzles me: Felimare picta. They sometimes (not always) show a significant depression in the position of the eyes, a process which is part of the evolution of the eye to allow for the detection of the direction.

Jongrak Lee I have not saw nor heard an aeolid nudis having eye spot, yet. Some aplysiomorph do.
João Pedro Silva Jongrak Lee, it's visible in Morten's photo, can't you see it? I can show quite a few from other species.... just a few examples:
- Calma glaucoides: http://www.flickr.com/photos/jpsilva1971/7427839434/
- Calma gobioophaga: http://www.flickr.com/photos/jpsilva1971/7229842190/

etc etc etc
Jongrak Lee Yeah, I'll check it out.:-)
Jongrak Lee I was mistakingly wrong. Got confused with sth else. Thank you for your comment.

João Pedro Silva Nuno, that's Peltodoris atromaculata, a common species in our area. When posting here, as this is a group more oriented towards studying sea slugs and less for sharing pretty pictures, keep in mind it's important to say where it was taken including depth and time of the year as this information may prove useful.
João Pedro Silva If you're interested, go through my blog to meet some other sea slugs in our area and also identify further observations:
http://hypselodoris.blogspot.pt/
João Pedro Silva I went through some of your photos of nudibranchs and spotted a couple of misidentifications (one Felimida purpurea identified as Felimida krohni and a Felimare cantabrica identified as Felimare picta) but I'm unable to comment there.
David Kipling Contrary to what Dawn Watson thinks, I do not have a supply of model nudibranchs that I take with me on dives ;)
These are from the National Museum here in Wales, made of Fimo I think!
Christian Skauge I have a kit like this, bought on eBay from Japan :-)
João Pedro Silva My wife makes bijoux with Fimo professionally and I've been trying (for ages!) to convince her to do these models with the portuguese species.
Christian Skauge http://www.facebook.com/photo.php?fbid=1550708580196&set=a.1157771997027.24269.1609584836&type=3&theater
João Pedro Silva Hurrah! I've shown my wife these models and she asked me to pick 6 species for her to make until June :)
Bernard Picton Tell your wife it's a very noble tradition. These glass models were traded widely and many museums still have some. There was a conference about them in recent years in Dublin.
http://en.wikipedia.org/wiki/Leopold_and_Rudolf_Blaschka
Bernard Picton Christian Skauge, for your contact who wanted Glaucus, NM Wales have a Blaschka one!!
http://www.museumwales.ac.uk/en/rhagor/galleries/blaschka/
Christian Skauge Do you have dates for June? Been away a few days (Nudibranch Safari, of course!) and haven't paid much attn to FB...
Bernard Picton Or July?
Christian Skauge Fantastic glass figures - I want one!!
Bernard Picton I doubt if you can afford one, I'm afraid. But if you visit Ireland we could try and get to see the ones in National Museum of Ireland. It was closed to the public, but I have contacts.
http://www.ucd.ie/blaschka/
Christian Skauge Will do! I think I'll have to steal one, they seem a bit pricy... :-D
Bernard Picton Did you find a price?
João Pedro Silva Sorry, I don't have dates yet :(
João Pedro Silva I've sent a list of 8 species so she can pick 6: Flabellina babai, Hypselodoris villafranca (these are so common they are a "must"), Armina maculata, Marionia blainvillea, Diaphorodoris luteocincta, Dondice banyulensis, Chromodoris luteorosea, Cadlina pellucida. If these turn out ok I'm counting on you to convince her to the all the NE Atlantic species :)
David KiplingOkenia elegans of course!
Christian Skauge @ Bernard: Found no price, just a wild guess :-)
Gonçalo Calado Same with algarvian typical pastery http://www.imagesofportugal.net/media/471cd934-bdc1-11e0-acb5-57e8dc34769b-algarve-s-traditional-pastry-portugal
João Pedro Silva I usually describe Platydoris argo as a pancake orange underneath with sugar on top.
Bernard Picton Now don't go there... Seasearch keep inventing common names for things, Amphilectus fucorum = shredded carrot sponge - trouble is they are always food related...
Bernard Picton Pentapora was widely called ross coral (I think a typo for rose) but they invented potato crisp bryozoan....
Christian Skauge hahaha I always get hungry when finding a sea sausage :)
João Pedro Silva All the nudibranchs here in Portugal share on common name: "nudibranch". Except for Peltodoris atromaculata: "vaquinha suÃça" (literally, "swiss cow", a dairy Holstein breed cow).
Becky Hitchin I have some plastic nudibranchs from Japan :)
David Kipling I have to say that I am disappointed that the National Museum (which tends to focus on welsh natural history) has a display of purely tropical nudibranchs! I think we should get João Pedro Silva's wife to make an extravagant set of NE Atlantic nudibranchs to replace them, to show that the Atlantic has species that can easily rival those in the tropics.
David Kipling Although we might have to make the Dotos a bit larger-than-life!
João Pedro Silva Aqui em Sesimbra são mais comuns do que F. affinis, embora não tão comum como F. pedata, e chegam a ter mais de 2cm.

Manuel MartÃnez Chacón Una ischitana preciosa... que suerte que sea allà tan común. Aquà es la affinis la más común y luego la pedata.

João Pedro Silva One of the many (lost count...) large (>5cm... more close to 10cm) Dondice banyulensis we found yesterday in Arrábida, Portugal.
Linda Goldrich Hi,
I'm currently out of the country leading a group dive trip.
I will respond to all emails when I return the end of June.

Ana Karla Araújo Does anybody have any paper about Dondice banyulensis with its radula? Thanks!
Vinicius Padula I need to check but...anyway, take care about radula. Even more it seems to be not so informative (or not informative at all). Good if you have a series of specimens and can check intraspecific variation, including ontogenetic, before conclude to much in comparison to literature and other species.
Ana Karla Araújo Ok Vinicius Padula, I'll take care! =]
Ana Karla Araújo But several studies show a radula for an specie and I find a radula different for supposed same specie, may not mean something?
Lucas CerCur Ana Karla, there is a paper of Francisco Garcia y Jose Carlos Garcia Gomez published in 1984 in Cahiers the Biologie Marine in which it appears the information that you ask.
Lucas CerCur It was published under the name Godiva banyulensis.
Lucas CerCur Nevertheless, Schmekel and Portmann (1982) included this information also.
Ana Karla Araújo Thanks Lucas CerCur
Lucas CerCur Ana Karla, do you have some of these two references?
Ana Karla Araújo I have the first one, but they didn't show a photo or draw of the radula.
Lucas CerCur Ana Karla, the Cahiers de Biologie Marine paper includes the draws of the jaws and one radular tooth of Dondice banyulensis, although the species is named Godiva banyulensis.
Ana Karla Araújo Oh sorry, it's another paper about Godiva banyulensis that I have. It's from Journal of Mollusca Studies. My mistake.
Lucas CerCur So, I infer that you lack the paper that I have referred, isn't it?
Ana Karla Araújo Yes!
Lucas CerCur I'll scan and upload it. OK?
Ana Karla Araújo I do not want to give you work, Lucas CerCur!
Lucas CerCur Don't worry.
Lucas CerCur Ana Karla, I have just to send the paper that you need.
João Pedro Silva Lots of juvenile Dondice banyulensis in last wednesday's dive in Sesimbra.
Yolanda Camacho Hi there,
I will be on vacations from July 11 to July 25. I will get back to you as soon as possible after then. Yolanda
Hola,
Estar� de vacaciones del 11 al 25 de julio. A mi regreso contestar� a su mensaje. Yolanda
João Pedro Silva (2nd time I've seen auto-reply messing around with comments on Facebook and something tells me this will intensify next month)
David Kipling Cute species, very "bad hair day"! Looks very small, yes?
João Pedro Silva Yes, this was just over 1 cm long. They often have their long cerata straightened, even the adults. Juveniles are a lot more transparent and have fewer cerata... adults are huge 7cm long fiery looking beasts: http://www.flickr.com/photos/jpsilva1971/4935784412/
João Pedro Silva Lots of these eggs masses around today, mostly associated with Alcyonium glomeratum (I think...). Don't recall seeing them at this place before. Any idea on the "parents'" ID?
Also found Tritonia hombergii for the first time today, rolling on the sandy bottom. No Alcyonium digitatum in sight, though.
Peter H van Bragt Where these spawn big and fat??? Could very well be T hombergii
João Pedro Silva Not sure how to handle "big" and "fat". They were rather big but the diameter was ~5-6cm. Some were slightly pink.
http://www.flickr.com/photos/jpsilva1971/8448904534/
The single T. hombergii I found there was ~4-5cm long.
João Pedro Silva The size reminded me of the spawn of Dondice banyulensis but these are thinner and very different in shape:
http://www.flickr.com/photos/jpsilva1971/5190093660
Peter H van Bragt Pink is often seen in T hombergii spawn. One can never be sure but it seems to be a candidate.
Jim Anderson These look like Tritonia hombergii spawn to me.
I have a few examples here
Jim Anderson http://www.nudibranch.org/Scottish%20Nudibranchs/tritonia-hombergii.html
João Pedro Silva Thanks! I hope they're still around next week :)
Tony Gilbert Check out Tritonia plebia's spawn, if there are any piks for that.
There maybe a subtle difference between the two. T. plebia likes A. digtatum, not so sure about A. glomeratum though.
Jim Anderson T. plebeia spawn is quite different and considerably smaller - see here
http://www.nudibranch.org/Scottish%20Nudibranchs/html/tritonia-plebeia-spawn.html
Tony Gilbert Thanks Jim, always good to discount what is not.
