Jørn Ari Need help with id. This smal Flabellina was found in Denmark, July 2013, size 6mm, watertemp 10 (celcius), depth 25-30m

Bjørnar Nygård Looks like Flabellina pedata

João Pedro Silva Agree.

John Sexton not Fl Funeka?

João Pedro Silva That's a south african species, John.

John Sexton aha That is the disadvantage of using the ID app. It does not give range. I will be getting your book soon for this reason.

João Pedro Silva Another advantage is that you can get it signed on our next dive :)

John Sexton Lol

Erling Svensen Just another picture from last night. Enjoy.....

Rob Maller Really beautiful

Carissa Shipman Wowsers!

Carlos Fernández-Cid Ramos Thank you.

David Kipling Is this Flabellina pedata with all that purple colour?

Erling Svensen Yes, David

David Kipling Great pic as well, you're very good at this!

Rachel Coppock Weston What an awesome photo!

Bernard Picton Dawn Watson, do you like these face-on ones? Makes you really relate to nudibranchs!

Becky Hitchin I am so in awe of your photography!

Erling Svensen Thanks, Becky! After 35 years I still feel there is much to do and learn.

Becky Hitchin Ah, after only a year of underwater photography, I feel I have more than the universe to learn!

Erling Svensen One must start somewhere. When I started it was with film and flashbulbs, and I had to wait 1 week to see what I did under the dive. Today it is very, very easy compared to in 1978.....

Becky Hitchin I can imagine! Though I still adore my (above water) medium format film camera and still use it. But I'm absolutely fascinated with photography underwater now, and diving seems horribly empty without a camera!

Patryk Uram SORRY for the quality of the foto :) foto was taken with compact camera canon ixus 700 in falmouth cornwall in uk :)

Gary Cobb The closest I can get is Flabellina pedata (Montagu, 1815) Also known as: Coryphella pedata

Ashley Missen Thanks Gary - please send to data@nudibase with the sighting info a I will add it to the database thanks Ash

Manuel Martínez Chacón Muchas veces los juveniles de flabelina son tan ambíguos que parecen de otra especie...

João Pedro Silva A mim parecem ambas Flabellina pedata.

Manuel Martínez Chacón Sí, lo son... pero la coloración es tan ambígua que parecen otra clase de nudibranquio.

Manuel Martínez Chacón Los rinóforos lisos los delatan.

João Pedro Silva Sim, as F. pedata podem variar muito na coloração dos cerata dependendo do que comem.

Tamsyn MAnn Only these two on my dives today where the photo was half decent. Saw a tiny (10mm) Flabellina pedata but pics hopeless after strobe ran out of battery and had surge and torch!! Jorunna tomentosa picture rubbish as well. Nothing to blame for that...!

Manuel Martínez Chacón La que faltaba en la lista... Flabellina pedata.

Gabriela Vergara Sanchez hola, disculpa me encontre este nudibranqui en un estero de Yucatan, México y quisiera saber si me podrias ayudar a identificarla, yo creo que el genero es flabellina pero no se la especie.

João Pedro Silva Porque dizes que o género é Flabellina? A mim parece da família Facelinidae.

Gabriela Vergara Sanchez tiene caracteristicas muy parecidas a flabellina

João Pedro Silva Bom, como muitos Aeolidida...

Gabriela Vergara Sanchez :(

João Pedro Silva Penso que as sugestões de Dondice spp. que o Vinicius Padula fez podem estar mais próximas.

Vinicius Padula Donde estan las otras fotos?

Vinicius Padula Gabriela Vergara Sanchez y João Pedro Silva, no sé donde estan las otras fotos del ejemplar para identificacion :(

João Pedro Silva Não sei se o tópico foi apagado. Mas fiquei aqui com o crop que tinha feito:

Vinicius Padula Dondice occidentalis (Engel, 1925)

Egidio Trainito Jim Anderson, Bernard Picton, and all the people in the group, I would like to have your opinion about the nudibranch I am posting. My opinion is that it is NOT Caloria elegant, but a sibling species: please look at the rhinophores (in C.elegans they're smooth), at the colour pattern of head and tentacles and at colour and assemblage of cerata. Thank you all.

João Pedro Silva I've got several shots of C. elegans, both with lighter cerata and with red cerata. I'm convinced it depends on the diet. The rhinophores arent's completely smooth in neither colour forms I find here in Portugal: http://www.flickr.com/photos/jpsilva1971/7408953742/

João Pedro Silva Same with yellow digestive gland visible inside the cerata: http://www.flickr.com/photos/jpsilva1971/5654832216/

João Pedro Silva But the most striking is this one where the digestive gland colour varies along the length of the cerata: http://www.flickr.com/photos/jpsilva1971/4784556408/

João Pedro Silva All my photos of C. elegans can be found here: http://www.flickr.com/photos/jpsilva1971/tags/caloriaelegans/

O Gajo Dos Olivais I noticed that the rinophores aren't smooth. Maybe the "definition" of smooth is not quite right :) All pictures I've seen from JPSilva and others, showed the rinophores with those "bumps". But they are not lameled...

João Pedro Silva They appear to have small translucent papillae more conspicuous on the anterior side where there's white pigment.

Egidio Trainito Papillae are not lamellae, the first ones are only on the front side the second ones are only on the rear side. Is this in the variability of the species? I don't think so. The original description of C.elegans and following papers such as Schmekl and Portmann say smooth rhinophores. My records of C.elegans are all quite different than this (which appeared in recent years) and all with smooth rhinophores. Is there anybody in the world willing to study some specimen I have collected?

Bernard Picton Egidio, you don't say where the picture was taken? I agree, these rhinophores are not like the animals I've seen in the UK and Ireland, where the rhinophores have rounded papillae. They are not smooth. When I have seen Caloria elegans in the Mediterranean they have been much smaller, so perhaps the papillae develop in larger animals. Your animal seems to have lamellae on the rear side of the rhinophores, which is certainly odd. I just changed the photo on my site to a close-up. http://www.habitas.org.uk/marinelife/photo.asp?item=bep2_8297

Egidio Trainito Bernard, the photo was taken in Sardinia and this form of nudibranch appeared in recent years: while C.elegans is still present but non common, this has become very common in the places where I commonly dive, north east coast of Sardinia. It happened to me to find the two forms in the same dive spot. What looks strange to me are the lamellae on the rear side of the rhinophores, which I have never seen on C.elegans.

Egidio Trainito Bernard, I've looked at your photo and I've never seen in the Mediterranean C.elegans so clear and developed papillae. Quite strange to me.

Bernard Picton Very interesting. If you look at SSF there are quite a few photos, some look as though they may have lamellate rhinophores. It could be that we are dealing with several species here. It should be easily possible to resolve this with DNA sequences. If you have two things in the same place they are "sympatric" which should mean complete genetic isolation. Slightly more tricky if our UK ones are different, because they could be isolated by distance. Even then CO1 (barcoding) sequences in nudibranchs seem to be reliably distinguishing species. http://www.seaslugforum.net/showall/caloeleg

Egidio Trainito Bernard, this is exactly what I am thinking of: I have collected some specimen of the false Caloria and as soon as I am able to collect the true Caloria I will send them for a DNA test to Genoa university. Your opinion conforts me.

João Pedro Silva Re-checked some of my photos and found some of these Caloria elegans with distinctively lamellate rhinophores: http://www.flickr.com/photos/jpsilva1971/6721622707/ http://www.flickr.com/photos/jpsilva1971/6721625063/ All have red digestive gland. However, some with red digestive gland have papillae and not lamellae on the rhinophores.

Bernard Picton I think you need to change the text in the book, this must be a second species. Of course, we already have two names available, Caloria maculata with type locality in Italy (the lamellate-rhinophored one?) and Caloria elegans with type locality South coast of England. As I wrote the paper which synonymised them this is a bit of an embarassment!! :-)

Bernard Picton One thing to remember is that rhinophores do seem to have considerable evolutionary plasticity. Flabellina pedata and F. affinis, Flabellina trilineata and Flabellina lineata... http://californiadiver.com/flabellina-trilineata-nudibranch/

João Pedro Silva The photos we have on the book for Caloria elegans all have papillate rhinophores :)

Bernard Picton I think the text might include these ones a bit?

Bernard Picton I suspect that Aeolids are derived from an ancestor which had lamellate rhinophores, so the smooth state would then be a simplification and likely to happen many times.

Lucas CerCur I agree with this view.

Lucas CerCur So, Caloria elegans....another case of study.

Fabio Russo I was not able to see well the rinofores, "antennae", that make the difference between the F. affinis and F.pedata, but by the ditribution of Cerata I'm pretty sure it's a Flabellina pedata, yuo can read my note on Opistobranch here: https://www.facebook.com/note.php?note_id=254945317914263 For english spoken i'm Sorry it's only in italian!!!

Alessandro Diotallevi Buon giorno, Walter, sei sicuro che si tratti di Flabellina "affinis" ?

Walter Bassi Ciao Alessandro infatti mi sono accorto che ho sbaglisto.Forse e flabellina ischitana,se qualcuno puo aiutarmi

Walter Bassi Sorry,this sobject is flabellina ischitana?

Walter Bassi Ok,she is flabellina pedata sorry for error

Fabio Russo Hi Walter, this is now consider Flabellina pedata, you can read more one my note: https://www.facebook.com/notes/fabio-russo/capo-palinuro-gli-opistobranchi/254945317914263

Walter Bassi Thanks Fabio,you note is very interesting

Walter Bassi Thanks for the"like"

Alessandro Diotallevi Ciao Walter, scusami per il ritargo con cui ti rispondo. Si, è Flabellina pedata, il particolare che guida l'identificazione è la presenza di rinofori lisci, cioè non annulati, caratteristica che la differenzia dalle altre due specie simili (Flabellina affinis e Flabellina ischitana). Per quanto riguarda i cerata, si, potevano essere di Flabellina ischitana sia per il colore che per il fatto che con questa angolazione di scatto sembrano originarsi da un peduncolo comune. :-)

Richie West Bit baffled by this wee trio, can anyone help? I thought the very dark nudi might be Flabellina pedata but both it and the tiny white processed one look like they are munching on red algae, not hydroids. I have other pics which clearly show the larger one has been eating seaweed. And what about the nudi on the right with orange-tipped processes that looks like it's eating Nemertesia?

Sarah Bowen Orange swollen tips to cerata suggests Eubranchus. Now I look again at the dark one with white tips they look that swollen but pointy Eubranchus sort of shape....

Sarah Bowen That nice Mr Picton says that there's a colour morph of Eubranchus farrani where the normal translucent white can be replaced by a purple-black or tawny orange hue. And they eat Obelia geniculata, which often grows on algae. Sound plausible?

Jennifer Jones I agree Sarah, and congrats to you Richie for a brilliant photo showing different colour morphs!

Richie West Thanks Sarah and Jen. Mystery solved!

Kerry Lewis Wowsers!

João Pedro Silva The dark ones are Eubranchus farrani. The smaller one has the characteristics of Eubranchus linensis (white tips of the oral tentacles and rhinophores) but E. farrani is so variable and the one on the left has also white tips of the rhinophores and oral tentacles... but definitely not a Janolus.

David Kipling Just so I'm clear ... there are three nudis here. [1] Biggest, far left, dark with white tips. [2] Middle sized, right hand side, orange tips. [3] Smallest one near middle/bottom, grey with white tips. Which are you saying is which João Pedro?

João Pedro Silva [1] and [2] E. farrani; [3] E. linensis OR E. farrani.

João Pedro Silva Check my latest of E. linensis (much more common than E. farrani here): http://www.flickr.com/photos/jpsilva1971/6919061696/

David Kipling I don't think we've ever had UK records for E linensis (according to NBN and Habitas).

David Kipling To me, [3] has the "feel" of a baby version of [1]. Richie West ... could you post a cropped version so we can see the little one in more detail please?

João Pedro Silva That's why I'm in doubt regarding [3]. I also think it's more likely to be E. farrani. But there are records of E. linensis as far north as The Netherlands.

Jennifer Jones I think all three are E. Farrani

O Gajo Dos Olivais Hello all. I've been reading a lot and trying to learn more from everyone posts and books referred. For what I have read until now, I have never learned that Flabellina pedata eats eggs... But I think I have seen it. The picture annexed shows what I'm saying. The F. pedata on the front is upside down and I think it is eating the eggs instead of placing them. There is another one near (in second plan) and there is also some "eudendrium" near. I thought it was laying the eggs but ... can any one enlighten this please?

Egidio Trainito Both eggs and nudibranch are on the stem of an hydroid and I think that the nudibranch is eating its usual food, the hydroid. Many times things are more simple than what we think.

O Gajo Dos Olivais Yes, I though so as well. But I was in fact unable to see if the eggs were being eaten. All I was able to see was that the eggs disappeared after a while.. but they could just got released and lost. I'm sorry for not having more pictures.. The sea wasn't being very nice to me and my camera :)

João Pedro Silva I agree with Egidio Trainito. Often we see them eating away and it's only natural some other things on the hydroid getting mistaken by food. Nudibranchs feeding on eggs (for instance, Favorinus branchialis) are more obvious on their choice of food source. http://www.flickr.com/photos/jpsilva1971/7551439102/

O Gajo Dos Olivais Ok. You are (as I also thought ) probably right. Even if some eggs were eaten they would be a "collateral damage". Thanks.

Gary Cobb Collateral damage is right...dont get your finger in the way!

Tony Gilbert Interesting colouration for a Flabellina pedata, found on West coasts of Scotland, usually most I've seen have a more distinct purple colouration (as can be seen by the other two in the album). This is much more like an F. affinis (which has a more southerly distribution). The key id features for this UK F. pedata are the annulate rhinophores are less lamellate, and more importantly the cerata are less pedunculate - from the body. The length was more like 30mm, rather than average 20mm. At first glance you could be mistaken in thinking it was F. affinis - so was lucky as I've seen many F. affinis in Canary Islands. https://www.facebook.com/media/set/?set=a.236433703157387.57884.100003722780643&type=3#!/photo.php?fbid=236433903157367&set=a.236433703157387.57884.100003722780643&type=3&theater

João Pedro Silva F. affinis has opaque purple pigment near the tip of the cerata.

Bernard Picton The rhinophores in F. pedata are not annulate at all, Tony, not less.. The way things are moving about these days we'll have to start collecting and checking when we get something like this which seems to be off the edge of the normal range of variation....

Lucas CerCur I'm uploading a short paper that can help to thid issue.

Jim Anderson You can see the range of colours I've recorded here http://www.nudibranch.org/Scottish%20Nudibranchs/flabellina-pedata.html

Lucas CerCur Jim, this is the same tale that A. papillosa. We have discover that in Europe are more than one species under this name because we are studying the family around the Word. But the same can happens with violet Flabellina in Europe.

Lucas CerCur In fact, Flabellina ischitana (fron the Gulf of Naples) was considered by all people as F. affinis.

Lucas CerCur In fact, Schmekel and Portmann (1982) called as "aberrant F. affinis", beacuse, its reproductive system was different from the typical of F. affinis.

Lucas CerCur It is included in the Doctoral Thesis of a Moroccan student that I'm advicing.

Lucas CerCur The description is not published yet.

Jim Anderson Lucas - do you want samples of any of these purple Flabellina I come across?

Tony Gilbert Thanks Bernard Picton for the clarification... as always :-) Jim Anderson, I photographed a similar one on Inish Is (the wall), Firth of Lorne, May 2012, depth 15-22m. This maybe more accessible. https://www.facebook.com/media/set/?set=a.236433703157387.57884.100003722780643&type=1#!/photo.php?fbid=237742786359812&set=a.236433703157387.57884.100003722780643&type=3&theater It is interesting to see these variations, and can send images on request.

Bernard Picton Great observation Tony, I'm sure we need to take another look at these... I note too that the radula of Coryphella lineata in the Mediterranean was a bit different to ones from Ireland. At the time I put it down to the range of variation, but it's another one we should look carefully at...

João Pedro Silva Very few F. pedata here right now but still I found one today: http://www.flickr.com/photos/jpsilva1971/8386696607/

Tony Gilbert I'll be looking out for the purple opaque tips then, is this diagnostic for F. affinis - all variations of, or just Portugal Joao?

João Pedro Silva The purple opaque tips of the cerata are characteristic of F. affinis alone, at least in this area.

João Pedro Silva Here you can see it in more detail: http://www.flickr.com/photos/jpsilva1971/5830437031/ In F. pedata, the cerata haven't got this superficial pigmentation.

Tony Gilbert Btw, has anyone seen this colouration (my original post image) south of West Scotland or north of? (is it a northern variation, only on West Atlantic coasts).

Tony Gilbert Thanks João Pedro Silva, sorry I meant F. affinis and not F. pedata (that doesn't have the purple tips). Purple tips maybe diagnostic for your area, F. affinis (Lanzarote) doesn't seem to have them. http://www.flickr.com/photos/tonyjgilbert-images/7102523395/in/set-72157629775715919/

João Pedro Silva The purple superficial pigment on the cerata spreads over a larger area of the cerata, not as concentrated near the tip as in the individuals we find here, but it's still present.

O Gajo Dos Olivais This specimen have a bifurcated ceras. But besides that, and considering no suspension or sensor dust, it looks like having two eyes on the same side. Any other cases? Unfortunately I only saw it when processing and it is the only picture I have of this specimen... Flabellina pedata, at Baleeira, Sesimbra, Portugal, 8 meters depth, 2012 July 28.
