Paula LightfootCuthona caerulea? From the north side of Filey Brigg.
João Pedro Silva Would like to see the rhinophores, but I do think it's C. caerulea.
David Kipling Looks the right colour scheme from what I know, can't think what else it might be. How big?
Erling Svensen This is the caerulea, yes. Very tiny - less then 1 cm?
Paula Lightfoot Thanks everyone! Yes very tiny, less than 1cm. I don't have a photo showing the rhinophores, that's the best photo I got (I need a macro lens!)
Julia Nunn caerulea agreed
Tony Gilbert Tony Gilbert Nice one Paula. Yes, I agree also that it is C. caerulea. I've images from North Sea of this as well, so easy to compare:

Paula Lightfoot Beautiful photo Tony! There are no records of Cuthona caerulea for Eyemouth on the NBN Gateway. Where do you send your records?
Tony Gilbert Hi Paula,
Thanks for the complimen! That's interesting. I haven't recorded this particular one, but usually I record in MarLIN. The distribution is all british coasts, I guess, perhaps under-recorded owing to its small size.
I found these at the end of Nestend Gully, under a small overhang at the base of an isolated rock, passed the slope of pebbles - I know exactly where, so know where to go back to - if the weather allows us (hopefully in 2 weeks time).
Please advise on what you would like me to do re: recording it.
Paula Lightfoot Recording in MarLIN is great, that will get the records onto the NBN Gateway. Alternatively, you could do Seasearch recording and then you can record information on habitats as well as species: www.seasearch.org.uk Hope you have good conditions for your next trip!
Tony Gilbert Ok, thanks Paula. I love Abbs/Eyemouth its a great place, shame about recent weather though. If we can't dive there, we'll jump into a couple of sea lochs on the west coast instead :-)
Erling Svensen A picture from yesterday dive. The Cuthona caerulea is now in the harbour. I got three of them yesterday. One of my favorite nudies....
John de Jong Nice, I only know them from Spain. http://www.jojodive.nl/Nudy%20branches/European%20Sacoglossa%20and%20Nudibranchia%20(Spain)/slides/Cuthona%20caerulea%20(Spain%202008).html
João Pedro Silva Here they're usually very very small. Have you got both variations?

David Kipling I've only seen this once, and "forgot" to show it to Sarah until after the dive. It took a lot of chocolate before I was forgiven!
Erling Svensen It is not easy to see, only 5 millimeter long - and the age do not any good for my eyes, so I dive with a "Sherlockholms"loupe that I can use (plastic one) underwater when looking for really small stuff....
Christian Skauge Fantastic! Thos one I have never seen in Norway... well done :-)
João Pedro Silva For a long time I could only find them as "uninvited guests" in some other species' photos:
http://www.flickr.com/photos/jpsilva1971/5780102291/
PS: the H. cantabrica in the photo was relatively small, no longer than 2cm.
Erling Svensen As I have said before, Christian - you are much velcome to have one in your book - or just come to Egersund for diving on your way to Gulen..... ;-)
Torkild Bakken We see them from time to time in Central Norway, but they are not common. That may relate to thier size though. If I remember correctly I have seen them with hints of red on the cerata.
João Pedro Silva Some have clear body, cerata and rhinophores. But some have a white opaque median line extending to the oral tentacles and two other along each side of the foot. These also have yellowish pigment on the tips of the oral tentacles and rhinophores:

Quique Faure Garcias!!!!! Cierto , pequeña però con colores muy vivos .
Victor Sanchez Que chula Quique! Hoy he visto una muy muy pequeña, he ido a buscar las viridis. Por cierto has estado por Mataró hoy? Con lo de la posidonia no te visto!
Quique Faure Nooo, hoy en Palamós , Boreas y la Roja.
Como a ido lo de la posidonia?????
Victor Sanchez Bien! Primeros metros agua sucia abajo unos 8m de visibilidad. Mucha mata arrancada pero ya sabemos la cobertura que tiene. A segunda hora he vuelto a meterme con el scooter que tienen por allÃ. Un juguete muy chulo jeje. Por cierto el proximo sabado hago el boreas de noche! Un abrazoteee
Kirstie Harris Found this in Pembrokeshire this w/e, any ideas what type it is?
Terry GriffithsCuthona caerulea
Kirstie Harris Hi Terry, thanks for the speedy reply.
David Kipling Very nice!
Kirstie Harris I can't take credit, it was my hubby's spot and photo :)
Sarah Bowen Fab spot - very jealous - only ever seen pics (unless you count the one attached to a hydroid in a dish the other weekend). Can you remember what site? We're down in Martin's Haven this weekend.
Kirstie Harris It was on The Stacks.
Kirstie Harris Sorry, Stack Rock.
David Kipling Sarah, you're supposed to be doing a fish survey, I'll tell Kate you're planning on going off-piste!
Sarah Bowen Who said I was planning any such thing; and stop hijacking this thread about a very tiny, pretty nudibranch!

Kerry Lewis Here's a Cuthona caerulea.... and a Cuthona somethingelsus maybe? I know they aren't great shots, but any offers?
David Kipling Yes, Cuthona viridis. Bright green ceratal contents give it away (as name hints).
Kerry Lewis I wondered that... I hoped that! Two new ones! :-)
Kerry Lewis Richie West how did your piccies of these two come out?
Richie West I still haven't gone through my pics from Scotland yet, that's how far behind I am with my photos... I'll have a look now xx
David Kipling You do realise that pretty much everyone on the survey saw Cuthona caerulea apart from Sarah? She's not happy!
Kerry Lewis Sarah, if it's any consolation, I have the same relationship with Okenia.
David Kipling Doesn't help that the only time I've seen this species underwater was on the fish survey 4 years ago, and I failed to show it to my buddy at the time :(
Richie WestCuthona caerulea was clear in my pic Kerry but C. viridis was out of focus, your photos were better
David Kipling Oh so Richie saw it as well ... !!!
Kerry Lewis Well... to be fair, I don't think Richie had the foggiest what I was pointing at... he just stuck his camera in vaguely the right direction and got lucky...
Richie West As usual though David I had no idea what I was looking at until Kerry told me on the surface
Richie West (she's always right lol)
David Kipling Even when she's not!
Richie West *gasps!* perish the thought
Kerry Lewis Always when I'm not.
Erin Smyth Pretty.. . . .
Richie West I may yet be able to crochet Sarah her very own Cuthona collection
David Kipling Depends if you want her to fill it with lead shot and chuck it at you!
Richie West I already have a very hush-hush order from Kerry for an Okenia elegans for her bcd pocket, although I think Kate and Aran's plasticine version will take some beating.
Richie West After the crochet blouse with matching headband from my new pattern book that is
Sarah Bowen You lot will get chucked out of this group for hijacking perfectly sensible threads with this sort of craft nonsense!!! But yes please, I'd love a crochet Cuthona!
Richie West I will pay particular attention to the diagnostic features with my crochet to make sure it's on-topic
Kate Lock Well done Kerry Lewis - definate nudibranch queen award. I have just checked the Skomer MNR nudibranch list and neither of these species have been officially recorded in the Reserve before!! (although it looks like David Kipling is claiming to above he did not tell us and obviously did not complete a form!!)..... Would you mind doing an Observer form for the dive so we can have these as official records :)
David Kipling My spot was on the 2009 fish survey on Rye Rocks, and I remember someone who shall remain nameless saying "oh no, I don't want a Seasearch form done for the dive, we've done Rye Rocks to death" or something to that effect ;)
Erin Smyth Do you think if we made the surveys for nudibranchs people would hunt for and photograph fish?! ;-)
Kerry Lewis Here's a Cuthona caerulea.... and a Cuthona somethingelsus maybe? I know they aren't great shots, but any offers?
David Kipling Yes, Cuthona viridis. Bright green ceratal contents give it away (as name hints).

Henrique Nascimento Catarina just a small nudi, Trapania pallida (white), with another one even much more small..... Cuthona ocellata (blue & yellow)...4
Farilhões (Berlengas) - Portugal
20130710
Ron Silver Coloration doesn't seem right for C. ocellata. Looks like C. yamasui except it has not been found in this area to my knowledge.
Henrique Nascimento Catarina Ron, has you know, I'm not an expert...... it was João Pedro Silva who told me the name C. oceliata... maybe he read this post and can see if is OK or Not ? he is the expert not me, I just love diving and photo.... the names :(.... But thank you very much for your advertise.....
Ron Silver No criticism meant, Henrique. Joao is an expert, so let's see if he adds a comment. Thanx for posting your photos.
João Pedro Silva It's Cuthona caerulea :) No C. yamasui in these parts.
João Pedro Silva Ah, now I see it! You can only see the head and the rhinophores and part of the parapodia of this Elysia viridis!
João Pedro Silva Did you spot it while shooting or only after seen the photo on the computer screen? I've gathered a few dozens of what I call "uninvited guest" photos. The most dramatic find was of a Cuthona caerulea on a photo of a Flabellina babai... and it was found two and a half years after the shot was taken :)
João Pedro Silva This is my "uninvited guests" set on Flickr. Many nudibranchs but also parasites, copepods, shrimp, etc:

Christian Skauge Finally found one! I have been looking for the Polycera faeroensis for a long time with no luck until recently.
To many of you this species is not that uncommon, but up here in Norway it is a rare sight. Oddly enough it seems to be occurring quite often in the Kristiansund area.
Torjus Haukvik Congratulations! You are not the only Norwegian looking for that one! ;)
Terry Griffiths And there you go seen so many of these not unless there mating i don't bother taking photo's.
João Pedro Silva After diving here you'll be fed up with P. faeroensis :)
João Pedro Silva (I do say to my buddies "in case you find a pretty blue nudibranch... don't bother me")
Klas Malmberg Aquatilis Congratulations!
Rob Maller Congratz indeed Christian!!
Christian Skauge Thanks guys! It is always fun to see something "new", and it doesn't happen as often as it used to... way cool :-)
Torjus Haukvik You can try to "forget" some of your sightings, then it will happen more often again..! ;p
Eric van Andel the more you dive the lesser are the special sightings.... :-)
Rob Maller @ Torjus...yes, then all of a sudden it's there!!
Christian Skauge Smart move, guys :-D
Torjus Haukvik Exactly!
Helgi Winther Olsen I know a Faroe Islander looking for this small bastard!
Christian Skauge What?? You should have them all over the place - are they not your national animal?
Helgi Winther Olsen I often wonder if they were named by the Faroes because they are so bloody difficult to find there!
Torjus Haukvik Isn't it the normal way to do it? Name it after a place where it's hard to find? ;)
Christian Skauge Polycera inyourfacia :-)
Helgi Winther Olsen Polycera Whereareyouia
David Kipling Well they're releasing European beavers back into the Welsh countryside, so we'll bring some of these to Gulen and release them in return - given you your breeding population ;) Would you like some Tritonia lineata as well? A common as muck round here!
Christian Skauge LOL :-) I would trade you a Berghia norvegica for a Cuthona caerulea though ;-)
David Kipling Which of the two do you get at Gulen?
Christian Skauge The Berghia - and except for the original discovery in 1939 this is the ONLY place it has been found ;-)
Arne Kuilman Congratulations! These are also very rare in the Netherlands. Polycera quadralineata is very prevalent over here.
