Ancula gibbosa

Paula Lightfoot Ancula gibbosa I think - from the Durham Heritage Coast

Ian Smith agree

João Pedro Silva I too agree.

Erling Svensen Ancula gibbosa from the harbour today.....

Jørn Ari Have a look inside an Ancula gibbosa.

Christian Skauge ha ha weird :-D

Erling Svensen A good friend took this picture which we think is Ancula gibbosa at Bodø in northern Norway. Do you have any other suggestions?

Ian Smith Hi Erling, it looks exactly right to me. Description at http://www.conchsoc.org/spaccount/Ancula-gibbosa

Klas Malmberg Aquatilis Q.E.D

Bernard Picton The two tentacles at the base of each rhinophore are only found in Ancula. This picture shows them very nicely.

David Kipling How big was this? I've only ever seen one, a stray that was climbing over an ascidian that I was photographing (oops).

Vebjørn Karlsen It is about 15 mm long.

David Kipling Wow, big one!

David Kipling This is another "didn't see it on the dive" nudibranch. Very small (as judged by the hydroids alongside and the heavy crop needed!), climbing over a solitary squirt on a north Cornish reef. Only shot I've got and not posed as well as one might wish. I think the head is at the bottom if that helps!

Ian Smith Ancula gibbosa with tail tucked in?

David Kipling That was one thought, yes Ian. It's been recorded in Mount's Bay, and this was round the corner on the north coast (OK a bit of a crawl for it I admit!).

Ian Smith Hi David, I think A. gibbosa isn't uncommon at sizes usually overlooked on the shore/dive. I find it fairly frequently while searching stones or scrapings brought home for examination under stereo microscope. I even scraped a 2mm one from an old sand-bag on the shore of the murky Mersey. It was a frequent find when I lived in Orkney - six of them on NBN.

Jim Anderson Looks like Ancula gibbosa to me.

Bernard Picton Yes, David, Ancula. I wonder if Joanne Porter can tell us if those lophophores are Bryozoan or Kamptozoan? Could be its food...

Joanne Porter Looks like Nolella to me

Marco Faasse The lower left tentacle crown looks different, like an entoproct (=kamptozoan); it seems to have a brown stalk with a bulbous body above it. Slightly higher there is probably a hydrozoan.

David Kipling Thanks Joanne, I see what you mean: http://www.sms.si.edu/irlspec/Nolell_stipat.htm

Mike Bartick Guess who i am and where i live....

Gary Cobb Ancula gibbosa (Risso, 1818) This species can be found in Alaska, Canada, Russia, northeast USA, south Korea, Scotland and north east US. It also has an all white colour form and is a cold water species.

Gary Cobb I must confess Mike I do have an advantage. I am working on the East Pacific Region Nudibranch ID iPhone App. It took me about 15 seconds to find it! I hope to have the App completed by the end of next month. There is as of right now 430 species represented.

Mike Bartick i know, i know....

Mike Bartick That wasnt meant to stump ya....lemme look for a stumper,,,

Ashley Missen Please send to data@nudibase so I can them to the database - with sighting Info - Thank you Ash

Gary Cobb I know I know!

Gary Cobb ...a stumper huh? Bring it on!

Erling Svensen I do not find another name for this one than Ancula gibbosa? From Norway, 8 meters of seawater, 2 degrees in the water - today. The nudi only 5 - 7 millimeter long.

David Kipling Certainly looks like it to me, and easier to identify than David Fenwick's specimen ;)

João Pedro Silva I agree it's Ancula gibbosa.

David Fenwick Snr David you'll be relieved to know I've just been on ebay looking at snorkeling equipment. Hopefully I'll find some larger ones just out of my normal range. LOL.

Erling Svensen Jippiiiii, a new specie for me (number 60 aprox. from Norway)

João Pedro Silva David Fenwick Snr, even at the surface, it's better to shoot the subjects submerged to preserve their shape. For instance, this Roboastra europaea was found during the low tide on the beach and the photo was done without any underwater housing (but with external strobes...) from the surface: http://www.flickr.com/photos/jpsilva1971/6824833932/ Out of the water it looks like a psychedelic blob.

David Kipling Dave and I used a Tic Tac mint container as an impromptu mini aquarium for a Goniodoris castanea on an intertidal fieldtrip earlier in the year ;) http://nachtwinkel-helmond.nl/wp-content/uploads/2012/07/TicTac.jpg I've probably got some pics of the tiny wee thing crawling around inside it - advantage being flat sides.

David Fenwick Snr We take out a number of containers with us on the shore; here it was a case of not seeing the slug because of its small size. A few of my best finds have been quite accidental and seen in images after I've got home. A lot of the time when we find a good rock on the shore we actually submerge it in a pool before taking it out to look at it. On muddy sites we'll take containers to fill with seawater and will look at rocks in the containers in clean water rather than have to wait for the water to clear around the rock.

João Pedro Silva "Seen in images after I've got home" is a familiar occurrence. Even on today's dive. Here are a few dozens: http://www.flickr.com/photos/jpsilva1971/sets/72157625904859297/

David Kipling Only time I've even seen Ancula gibbosa (well, it is small!) is on a picture afterwards.

David Kipling (Nice squirts btw João Pedro!)

David Fenwick Snr Fantastic Joao, glad it happens to others as well. LOL.

David Fenwick Snr Think my best one was accidentally taking a cyst of Myzostoma cirriferum on Antedon bifida http://www.aphotomarine.com/starfish_feather_star_rosy_antedon_bifida.html

David Fenwick Snr Here's a closer image of the slug on the egg mass

Bernard Picton I think David Kipling is correct in saying Ancula gibbosa. The spawn coil looks like Goniodoris nodosa, so the position is just a coincidence...

David Fenwick Snr Thanks Bernard and David

David Fenwick Snr Can anyone explain what's going on here with this sea slug egg. Elysia viridis and Facelina auriculata were on the rock and the egg was similar to others with E. viridis. It's the orange dotted transparent area at the 11 o'clock position that I'm interested in, seems strange for it to have come from an Elysia.

David Fenwick Snr It's almost as if a small Limacia clavigera was caught on the egg as the tide went out but it seems too transparent for that.

David Kipling Semi-transparent blob with yellow dots ... if it's a nudi, how about one of the Polyceras or Ancula gibbosa? Not sure if you get them that shallow.

David Fenwick Snr Yes both recorded shallow here so very possible.

Christian Skauge Colorwise it looks like it could be an Onchidoris luteocincta :-)

David Kipling I see what you mean - there's a little red mark. Is this part of the animal David (as opposed to being underneath or a bit of stray red weed)?

David Fenwick Snr The redness appears to be part of the animal but I cannot be sure; the spotting is on the surface the red below. The surface of the animal appears to be finely granular. Will add another image.

David Kipling Ancula is found close to Bottrylus ascidians according to habitas, so would be right for the sort of things you get under rocks. It also has a circular spawn by the look of it from Bernard's picture. Perhaps those are actually its eggs? http://www.habitas.org.uk/marinelife/photo.asp?item=bep2_3285

David Fenwick Snr There wasn't a lot about on the habitat yesterday, pretty low diversity, the reason I kept an eye open for slugs was that there was quite a bit of Alcyonidium gelatinosum about and I found the Elysia and Facelina soon after discovering it. Just a pity I didn't actually see the small slug on the egg mass to get it in water to photograph. Yes ascidians about but no large masses of them seen. So could we be dealing with a spent slug after it has laid?

Becky Hitchin I've officially given up trying to ID nudibranchs, especially TINY nudibranchs. Is the yellow / white one a small P. faeroensis? But I couldn't see any yellow oral fringey bits.

Marco Faasse It's less common/more special than P. faeroensis in my opinion :-)

Becky Hitchin I think I only know yellow and white nudis that have that yellow oral fringe. Hmm. Goes to look at Scottish Nudibranchs ...

Becky Hitchin Ancula gibbosa?

Marco Faasse I'm sure you'll be able to find what it is ...

Marco Faasse That's quick! I think so ...

Becky Hitchin I'd never even heard of Ancula, but I flicked through Jim's species and it does look right http://www.nudibranch.org/Scottish%20Nudibranchs/html/ancula-gibbosa-06.html

João Pedro Silva Yes, A. gibbosa.

Becky Hitchin A completely new nudibranch for me :D

Peter H van Bragt And Acanthodoris pilosa for the other tint one!

Becky Hitchin it was *so* small. It then occurred to me that I don't know how old that one would have been. Is that from last year? The year before? Has anyone looked at age sequences in nudis / Dorises?

Lucas CerCur Two of them are potos of Ancula gibbosa.

Peter H van Bragt most likely specimen from last years' spawn which developed from larvae to slugs this springbut this spring

Becky Hitchin That's just great :) now I want to look for more, and find it about larval / juvenile acanthodoris

Rachel Shucksmith

Anne Bignall How sweet - I see they have to 'grow in to' their rhinophores!

Terry Griffiths could be Ancula gibbosa ?

Rachel Shucksmith i thought he looked like dumbo the nudibranch...

Terry Griffiths Looks like the one on Habitas

Rachel Shucksmith it think your right terry

Sarah Bowen Great fun - has made me chuckle!

Ingrid Thea Ølberg you sure found out where the easterbunny came from...

Christian Skauge Cool! I think Terry Griffiths is right about the species :-)
