João Pedro Silva It's the only nudibranch with a truly common name which can be effectively used to identify it. In most of its range it is known as a "cow" (or variations within the theme) in several languages (portuguese, spanish, catalan, italian).
MarÃa Eugenia Suárez Cristina Montes es cierto, parecen oreos!
Cristina Montes ...siiiii.....
João Pedro Silva Não se trata da chamada "vaquita" 0;Peltodoris atromaculata) do Atlântico e Mediterrâneo mas sim de Jorunna funebris, do Indo-PacÃfico.

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.

Krzysiek Ro Gal Beautiful Lady :-)
João Pedro Silva Looks like a sea hare, not a spanish dancer which is a common name associated with a nudibranch (Hexabranchus sanguineus) not occurring in the Mediterranean (at least yet...).
João Pedro Silva It actually a cephalaspidean, a head shield slug: Gastropteron rubrum. More info at the Sea Slug Forum: http://www.seaslugforum.net/gastrubr.htm
João Pedro Silva This goes to show the use of common names in these animals is often misleading. Here's a post by Bill Rudman on the subject of using common names for sea slugs: http://www.seaslugforum.net/find/common
Ron Silver Use of common names period is misleading! Long live binomial nomenclature - even if it is constantly changing. LOL
João Pedro Silva Even then, Ron Silver. While writing the field guide on the Sea Slugs of the Algarve we had to do many changes: the Chromodorididae were all revised a few months before we delivered the manuscript.
Ron Silver I know. The use of genetic testing is basically rewriting the science (art?) of classification and certainly seems to be tolling the death knell of the 'lumpers vs. splitters' arguments of days gone by!
João Pedro Silva But this photo and the consequent comments have shown there are some exceptions. This was not a case of simply using a common name for several unrelated species: no one uses "spanish dancer" for Gastropterum rubrum. It is a case of misidentification. There are 3 or 4 common names in some languages which can be used to positively identify a species. One of those cases is precisely "spanish dancer" as everyone knows it refers to Hexabranchus sanguineus. Other is the Mediterranean and Atlantic Peldororis atromaculata which is called in several latin languages (but not french) "small cow" (and variations on the same theme). When someone tells me he or she has seen a small cow I can be sure they have seen Peltodoris atromaculata. Most of the other names are useless an can be used to refer several unrelated species even within the same distribution range (let alone in different oceans...).
João Pedro Silva I think there are "lumping" and "splitting" periods and even overlapping sometimes. And DNA analysis (actually, some scientists consider the gene loci used so far may not be good enough) may provide information which goes both ways. For instance, the latest revision on Aeolidiidae hints on Aeolidia papillosa actually being a complex of 3 species... and the control specimen used (from other families) hint towards Flabellina confusa and Piseinotecus gaditanus being the same species (I think synonymy was not proposed because it was out of the scope of the paper).

Ron Silver I surrender! :-D
Bülent Kılınç thanks a lot for the information you gave us Joao Pedro Silva and I will inform the local dive guides in Gökçeada Turkey.I was told that this critters have not been seen around there before and a kind of Spanish Dancer.
Bülent Kılınç I change the name of this critter as Gastropteron Rebrum
João Pedro Silva Glad to be of help, Bülent Kılınç!
João Pedro Silva Although this species is also present in the Atlantic, we haven't included it in our field guide. If you're comfortable reading french I recommend you a very comprehensive field guide for the Mediterranean with 171 species of sea slugs: "Des Limaces de Reve", by Sandrine Bielecki, Gilles Cavigneux, Jean Michel Crouzet and Sylvie Grall.
http://www.deslimacesdereve.com/
Although it's only 3 years old there have already been some changes in the nomenclature so it may be worth to check with WoRMS for the current valid names.

Phil Wardle This was taken 4 weeks ago in Malta and was told it is called Disco Doris
Phil Wardle
Phil Wardle if anyone could tell me actual name or is actually called Disco Doris?
Sylvie OmnèsPeltodoris atromaculata ( common name "dalmatian doris" )
Phil Wardle thks
Sylvie Omnès "Discodoris" is the name of another "family" of nudis .
Ken Hawkhead Have you seen one of them Pete
João Pedro SilvaPeltodoris atromaculata (previously was also known as Discodoris atromaculata). As Sylvie Omnès says, this one has common names which really point to a single species. In French, it's the "Doris dalmatien", in Italian it's "vacchetta di mare", in Spanish "vaquita", in Portuguese "vaquinha" (these three mean the same, "little cow"). At least for the species in this area, it's a unique case where I think the common name is useful and effective.
Gavin Bushell Could I have seen this in the Azores as well? I didn't have my camera but I am sure I saw one of these last week diving on the south coast of Pico, in about 20 metres on a vertical wall in very thin algae. About 2 cms long. I made a fairly good note of it on my slate.
João Pedro Silva Yes, they're actually more common in the Azores than in continental Portugal.
Gavin Bushell Brilliant, thanks so much.
João Pedro Silva They grow quite a bit. At 2cm long it was a relatively small individual.

Ab van Lenten According to wiki we are using a synonym, same species?
João Pedro Silva Quite, but you have to understand there are valid, accepted synonyms and unaccepted ones, usually junor (described later). That is why we don't use the invalid synonyms, otherwise we could still use Doris auriculatus, the name Müller gave to Facelina auriculata in 1776.
http://en.wikipedia.org/wiki/Facelina_auriculata
Ab van Lenten Ok, I see I need to read some more about this, thanks
Kirstie Knowles For those of us still getting up to speed with the taxonomy of these beasties, I find using WORMS (World Register of Marine Species) to be very useful (and user friendly to non-specialists). Obviously updates happening all the time but the WORMS editors are specialists themselves and pretty onto it.
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!

Stuart Pearce Beautiful Spotty Doris (thats what we used to call them anyway lol) :)
Claudia Weber-Gebert yes I know ...in spanisch they call them "sea cow" - I like it ;-) Thank you Stuart :)
Stuart Pearce We will both be in trouble later for using nicknames instead of scientific nomenclature LOL :D
Claudia Weber-Gebert I don't like scientific names...for me, those creatures are individuals and I can nearly remember every shot I made... so I really prefer the nicknames ;-)
Tony Strazzari I like sea cow ... they look like Friesians
Claudia Weber-Gebert :D

Antonio ColacinoPeltodoris atromaculata .nice shot,lives on Spongia Petrosia ficiformis wich is his food too.In Italy the common name is "vacchetta di mare" traslated in english "young sea cow" :)
Claudia Weber-Gebert Thank you Antonio Colacino - so I was not so wrong with "the horn of the sea cow" ;)
João Pedro Silva A 12cm long Peltodoris atromaculata from yesterday's dive in Farilhões, Berlengas, Portugal. Fortunately, the good visibility in this spot (~25m) enables us to photograph these "giants" with a 100mm lens.
Enrica TuminoDiscodoris atromaculata (Vacchetta di mare) - Nisida (Napoli)
Enrica Tumino Grazie, Wilson :)
Marlon Delgado Is this a Cow?? :P
Enrica Tumino Sure! A little cow! :) She is so pretty... :D
Gary Cobb This species is now known as Peltodoris atromaculata Bergh, 1880 as per Dayrat 2010
Enrica Tumino Thanks, Gary!!! You're right! "Discodoris" was the traditional scientific genus classification of this species, but recent studies reclassified this mollusk as a "Peltodoris" genus. :D
João Pedro Silva In my talks I usually say that nudibranchs haven't got common names... with the exception of this one in this area. I know for sure when people tell me they've seen a "little cow" they're referring to this species.
