David Serrano A mi plÃÂn, yo duermo en picolÃÂn :P, yo buceo siempre con el seco, pero por comodidad, lo cierto es que siempre buceo con el seco, da igual canarias, que el cantábrico. el agua se mueve entre los 13º del invierno y los 19º del verano. Lo que si te puedo asegurar es que cuando se deja en cantábrico es espectacular.
Christian Skauge Dorid nudibranch - it has gill bush at the back ;-)
João Pedro Silva This one is fairly common here and it varies a lot. I've seen some almost white and other almost orange, but always with the characteristic reticulate white lines.
Sven Kahlbrock Just found @ Thistlegorm, 23m approx 1,5 cm
Sven Kahlbrock does anyone have a clue?
Jim Anderson It's a dorid but that's the best I can do
Sven Kahlbrock will go the long trip to Wales anyhow ;-)
Mc Hamada ya sven ya gaaaaaaaaaaamed :)
O Gajo Dos Olivais Looks a lot like the Northern Atlantic's Doriopsilla areolata... But I don't know if that species exists at Red Sea.
João Pedro Silva It doesn't, Fernando, although it is hardly distinguishable from the Indo-Pacific Doriopsilla miniata:

However, I'm not convinced this is D. miniata.

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:

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.
João Pedro Silva 3 in 1: what was supposed to be a photo of Doriopsilla areolata + spawn turned out to be also a photo of Favorinus branchialis feeding. Shot in Berlengas, Portugal.
John Sexton Haha, nice shot. I just bought myself a magnifying glass to dive with just to be able to see this small stuff! Do you have your micro lens ready?
João Pedro Silva John Sexton, without a magnifying lens you've pointed me a tiny Tritonia plebeia (I had to shoot it and playback the image to make sure it was indeed a nudibranch). I guess I'll have to get myself a portable underwater electron microscope.
David Kipling That's almost wide-angle though. (Not to mention you need a vacuum for SEM or TEM). What you need is a cantilever AFM, that'll work fine provided you can control your buoyancy enough to hold it stilll ...
Gary Cobb Nice shot Joao!
João Pedro Silva I'll ask for one of Howard Hall's IMAX 3D housings.

O Gajo Dos Olivais To see them INSIDE the spawn is quite a tricky mission :)
João Pedro Silva Some say it's in fact the easiest way to find Favorinus branchialis. However, I've only found them feeding on very few occasions. Coincidentally, another time was also on the spawn of Doriopsilla sp.

O Gajo Dos Olivais That 3D housing for w3d is out for some time now. But the quality is not good and the camera will not do macro stereo pictures... the paralax is way too distant for macro. Loreo has one "Macro Lens in a Cap (9006)" wich I have and it's quite fine. I will take it next dive and get some nudi pics shot with it.
Tha good thing is that they will com out with SLR quality.. AND we can actually use a diopter from subsee or whatever one we have, like usually. The "counterpart" for me it's it builds an image in parallel eye vision (to use qith their viewer) and I see better (without viewers) in crossed-eye vision, so i will always have to edit the picture.
Henrique Nascimento CatarinaDoriopsilla areolata
Portugal - Cascais (201.07.07)
Henrique Nascimento Catarina Gary Cobb, the ohter shot is from this Nudi......
Gary Cobb Nice! I would like to call the animal I found intertidally Doriopsilla cf. areolata. At what depth did you find this one?
Gary Cobb I am building an iPhone App called Nudibranch ID Eastern Atlantic and want to know if I may use your photos in it? Full credit will given. Do you have many photos from this area?
João Pedro Silva D. areolata is found here at a wide range of depths. At least I've seen from -3 to -30m. Largest density in a particular spot between -8 and -11m.
Henrique Nascimento Catarina Thanks João Pedro Silva, this one, like the others I shot in this dive were at a depth of +/- 10 / 11 meters.....
Gary Cobb Quite a striking species, thanks for sharing!
João Pedro Silva Quite variable, too. Some brownish (http://www.flickr.com/photos/jpsilva1971/5893916479/), some more yellow (http://www.flickr.com/photos/jpsilva1971/4884974502/), some more orange (http://www.flickr.com/photos/jpsilva1971/6181370175/), some very pale, almost transparent (http://www.flickr.com/photos/jpsilva1971/4897130684/)
João Pedro Silva D. pelseneeri also varies in tone with paler individuals more frequent in the north of the distribution range.
João Pedro Silva It's funny that in spite of being hermafrodites most species have feminine names. Actually, the masculine names are the exception (Janolus, Eubranchus are masculine). I know I've only mentioned the genus but it's easy to see the specific epithet usually agrees on gender (sometimes it's even changed for that reason).
Gary Cobb Hey Joao nice thread and quite true! Do the rules state that when a species is described and named, no one can change it unless they prove it is another species? Genus changes don't change the species name.
Gary Cobb You're referring to genus right? It also seems that most species names are named after men.
João Pedro Silva The species named after men have the possessive form (like Aeolidiella alderi, which translates to "Alder's Aeolidiella") but most have actually attributes in the feminine form (for instance, Jorunna tomentosa, Doriopsilla areolata, Diaphorodoris papillata, etc).
João Pedro SilvaJanolus cristatus has the specific epithet in the masculine form to agree with the genus (otherwise it would be "cristata").
