Manuel Martínez Chacón Un ejemplar que me costó encontrar... Flabellina ischitana

Mabel Garcia Que bonita !!! El nudi y la foto :)

Manuel Martínez Chacón Gracias, fué una especie que buscaba durante meses y el día que menos esperaba... ¡apareció!

Mabel Garcia Pues de rara es preciosa ! Por curiosidad, cuánto mide esta ???

Manuel Martínez Chacón Pues era bastante pequeñaja, 1 centímetro quizás.

Mabel Garcia Ufff... me lo estaba imaginado ! Sois unos cracks los fotosub , unos cracks ! :)

Manuel Martínez Chacón No creas... sólo soy un aficionado con suerte. Por ahí rondan auténticos cracks que le hace un macro a los piojillos del bigote de una gamba.

Mabel Garcia Si, lo sé lo sé ! Tienen una paciencia inagotable ! :)

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. http://www.flickr.com/photos/jpsilva1971/5967063105/

Manuel Martínez Chacón Una ischitana preciosa... que suerte que sea allí tan común. Aquí es la affinis la más común y luego la pedata.

João Pedro Silva No Algarve encontramos as "3 Flabellina púrpura", por vezes todas juntas uma vez que se alimentam dos mesmos hidrozoários. Por vezes até junto com Cratena peregrina e Dondice banyulensis. http://www.flickr.com/photos/jpsilva1971/7791123034/

Manuel Martínez Chacón Que buen momento captado...

João Pedro Silva Nesse mergulho houve uma de F. affinis que suplantou todas :) http://www.flickr.com/photos/jpsilva1971/7790595020/

João Pedro Silva Cratena peregrina

Henk van Dijk ?

João Pedro Silva It's not Flabellina affinis, it's Cratena peregrina.

João Pedro Silva Here's an example of Flabellina affinis: http://www.flickr.com/photos/jpsilva1971/7790595020/

João Pedro Silva And here's an example of Cratena peregrina: http://www.flickr.com/photos/jpsilva1971/6081910869/

Henk van Dijk thanks.

João Pedro Silva You're welcome. The two orange bands on the head plus the orange tipped smooth rhinophores are a dead give away for C. peregrina.

Henk van Dijk Flabellina affinis ?

João Pedro Silva Yes, that's Flabellina affinis. But be aware there are two other purple Flabellina in the area and one of them is very likely to be mistaken for F. affinis: Flabellina ischitana, which lacks the purple superficial pigment on the top of the cerata. http://www.flickr.com/photos/jpsilva1971/5967063105/

Marco Maccarelli Buona Walter!!!!

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, à 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. :-)

João Pedro Silva Not much detail but the arrangement of the cerata makes me think it's probably Flabellina ischitana: https://www.facebook.com/photo.php?fbid=10152911938905641&set=a.10152911481660641.1073741835.589765640&type=3&theater

Ian Smith I hope Joao gets those kisses now for his effort ;-0

João Pedro Silva I decided not to identify those from "Africa" because I don't know if they're from the Mediterranean, the Atlantic or the Indian ocean.

Samantha Varns Xxx kisses an thank you xxx

João Pedro Silva Samantha Varns, next time you could allow comments on the album as it makes it a lot easier :)

Samantha Varns Sorry didn't realised it was blocked

Bernard Picton Could you add countries to the African ones?

Samantha Varns Easy they were all in Kenya diving off from mombassa the beach was Diana beach :-) xxx

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.
