Erling Svensen Have any of you ever seen gonads/eggs in the anemones? I have many pictures with this in the anemone Urticina eques and Urticina felina. Very nice.

Meg Daly This is a lovely picture! I have seen eggs in Anthopleura spp. and in a few others, but the color contrast was not so nice as these...

Andy Horton British sea anemones, notably Urticina felina can be seen to inflate, detach themselves and allow themselves to be carried to new locations. This is from aquarium study in response to unsuitable environmental conditions, usually too high water temperatures with the Dahlia Anemone. .

Cynthia D. Trowbridge Anthopleura elegantissima (Pacific) does this all the time as well

Christian Skauge Do you have the Stomphia coccinea in the UK as well? This species swims as well, especially if a spiny starfish comes along...

Bernard Picton We do find them, from Northern Ireland northwards. Haven't seen any in recent years here in Northern Ireland but they were in stony, current swept habitats where we haven't been doing much diving recently. In Scotland I've seen them on shells in more sheltered, sea loch conditions.

Christian Skauge They tend to be in a little more exposed places here as well. Quite small, but very beautiful - and with really interesting behaviour.

Paula Lightfoot Hi, could this be Aeolidiella glauca? Seen at 8.5m depth on Urticina felina. My first thought was the grey sea slug Aeolidia papillosa which is certainly common intertidally in Yorkshire, but this specimen doesn't have the V-shaped marking on the head.

Julia Nunn i think probably glauca - speckling on the back cerata

Brendan Oonk I agree

Andy Horton 4 June 2012 A rockpooling visit to Worthing Pier on a low (0.4 metres) spring tide produced a surprise Brittlestar as well as some infrequent summer occurences like two large Velvet Swimming Crabs, Necora puber, a handful of small Common Hermit Crabs, Pagurus bernhardus, in winkle shells, a single Common Starfish Asterias rubens, one Dahlia Anemone, Urticina felina, one small Long-legged Spider Crab Macropodia rostrata, and one sub-adult 5-Bearded Rockling, Ciliata mustela. A Greater Pipefish, Syngnathus acus, was rescued from the beak of a Herring Gull. Daisy Anemones, Cereus pedunculatus, were frequently found in chocolate brown hues. Snakelocks Anemones, Anemonia viridis, were common as usual with frequent Beadlet Anemones Actinia equina. Full Rockpooling Report http://www.glaucus.org.uk/LancingBeach2008.htm#4June (This came out like a list: I must be a bit tired.)

David Hill David Hill Andy - went on a Bioblitz on Saturday at Cemlyn Bay (north coast of Anglesey) and today rockpooling at Llanddulas (north Wales coast) - lots of interesting new finds (for me anyway, fairly new to marine life). Cemlyn included Eel, 5-Bearded Rockling, Butterfish, Lobster and Great Scallop - a few pics here www.flickr.com/photos/natureseye/sets/72157630042354134/ and list of species here http://www.cofnod.org.uk/BioBlitz?ID=6 At Llanddullas this afternoon lots of Sea Gooseberries and a few Pipefish, pics to follow.

Andy Horton The Greater Pipefish did not look injured when collected, but I do not think it will survive. The gulls catch these pipefish occasionally and drop them in gardens.

Joe Bater that would have been a great UW macro photography day!

Andy Horton Not so good on the photography front. Pier causes shadows and low light. Capture and return. I hope to get a few shots later. I was terrestrial and the critters were under rocks. More though. The young rockpoolers (8 yo) are well informed now.

Cathal McNaughton Found this earlier this evening, it appears to be a juvenile Dahlia anemone (Urticina felina), almost colourless and transparent. I couldnt quite get the focused shot I wanted, this being the best one I managed. Very small, a 5p coin would almost completely hide this.

Cathal McNaughton Just noticed there is a smaller one below it.

Andy Horton Looks more like Sagartia troglodytes

Andy Horton If you poke Sagartia elegans it should discharge acontia. Sagartia troglodytes probably won't. Classic Sagartia troglodytes colouring though.

Cathal McNaughton Thanks for this Andy and Dawn. Those are both new species to me, the 2 youve mentioned. I really thought this showed marking very similar to U felina and that it was a juvenile of that species. I was photographing mature U felina a few minutes before I found this tiny anemone.

Cathal McNaughton I think I'll have to go back tonight, find one of these and give it a poke to see what happens.

Andy Horton If you want to dig them up you would need at least a garden trowel.

Scubashooters Dot Net Hi Bart!!! Nice one! What's that???

Annette Graves Could be urticina eques, only guessing though, definately not my area of expertise!

Annette Graves Beautiful shot though!

Yutaka Takizawa Fantastic Shoot!

Holvoet Bart i'll look for the latin name!!

Yutaka Takizawa Cute Shoot!

Holvoet Bart Urticina felina

Annette Graves Well at least I got the Genus right, as I say not my area of expertise :)

Paula Lightfoot Here is its face (I picked it up and moved it to stop it looking down a hole!) - it's a bit blurry but you can see there are no V-shaped markings, which is why I thought maybe Aeolidiella glauca. It was about 3-4cm long.

Andy Horton Who's eating who?

Paula Lightfoot The slug is eating the anemones. On Arran we saw anemones eating jellyfish, gradually pulling them down by their tentacles!! Even a tug of war between several anemones over the same jellyfish!

Peter H van Bragt Hello Paula, for sure A. glauca. It's known to eat a variety of anemones: Like S. troglodytes and Diadumene cincta in Dutch waters. The latter one gives a nice reddish hue in this nudibranch. This seems to be Sagartia elegans? cheers Peter H van Bragt

Paula Lightfoot Thank you Peter ! I thought the anemones were Urticina felina, dahlia anemones, they just don't have as much debris stuck to the columns as they usually do. I saw a couple of Sagartia elegans at this site, but lots and lots of dahlias.

Bernd Lipsius warty column? dahlia

Steven Barnard Yep Urticina felina

Liz Morris Bernd Lipsius and Shôn Roberts, this could be either ... its a bit suspect that it doesnt have any gravel stuck to its column. Both species have warts, but Urticina felina's are adhesive so usually has gravel attached. One of your other photos looks more like Urticina eques, and I'm sure that both are present in the area. See more info on http://www.habitas.org.uk/marinelife/index.html for both species. If unsure put it down as Urticina sp, or both if you think both were present.

Bernd Lipsius

Liz Morris Nice dahlia - did you have a look to see if it had a sticky column? I think there were two species in the area - Urticina eques doesnt have sticky warts on its column, and is therefore clean compared to Urticina felina.

Erling Svensen Just want you to see how nice it can be in minus 1,7 C at Svalbard, Norway. Lots of Gersemia corals and Gorgonocephalus and many other nice things.

Becky Hitchin gorgeous!

Andy Horton I have changed my computer wallpaper to the top one. Must be a good view.

Penny Martin I have spent some time in Svalbard in 2009 and 2010 but never thought of diving there ... where were you ... near to Longyearbyen ??

Penny Martin and how deep ??

Keith Hiscock So, you know where the good reef diving sites are: will you write the guide please?

Andy Horton Are the anemone-like looking critters the Gersemia corals ? Or are they anemones?

David Kipling Do you mean the basket star in the top pic or those light brown large blobs to the right in the bottom pic, Andy?

Andy Horton Not the Gorgon!

Andy Horton I have got the top picture as my wallpaper. Because of the sea anemones and echinoderm.

David Kipling So the lower blobs then ;)

Andy Horton So what sea anemones are they?

David Kipling I have no idea - some weird and wonderful coldwater species I expect ;)

Andy Horton Urticina eques ?

Cath Waller Fantastic images. Would love to dive there. Out of interest what is the intertidal fauna (if any) like? Be an interesting comparison with southern polar.

Erling Svensen Hi everybody. I have been diving all around Svalbard on cruise with the University. The best diving are at Sagaskjeret in Isfjord and in Hinlopen on the East side. The anemones are Urticina eques, also commen here in Egersund. The Gersemia corals are brown, white, yellow and red and there are two kinds. The best stuff starts at 10 meter and down where the ice not is hard to the biology in the winter. Have you seen my book about the biology in Svalbard? I van make an album one day with cold water stuff from Svalbard if you want.

Andy Horton My guess is intertidal fauna is exiguous because of the meltwater, abrasive nature of ice and the extreme cold. Urticina eques, I have seen and the anemones do not match exactly but close. There is a sea anemone with a generic name beginning with B but that does not match either.

Andy Horton I think the explanation of the difference is that Urticina felina is sometimes identified as Urticina eques. This would certainly be true if these are typical U. eques.

Erling Svensen The u. eques at Svalbard grow to 30cm+ in diameter, and I have nice pictures with eggs inside the arms. Also the Urticina felina grows very big in the cold water, and the Cyanea capillata can be 2 meter in disk diameter and they lives for at least 3 years. So svalbard is special and a nice place to dive.

Erling Svensen If you want high res. pictures for desktop or what ever, just mail me and I can send some.

Andy Horton Erling Svenson: thanks. My computer equipment does not need a better picture right now. It is a bit late at night for me right now. Thinking though about the differences between A eques and U felina apart from size. The tentacles in the photograph are not so stubby and thick in dimension as I would normally expect from Urticina. The eggs U eques picture would be most interesting. I do not have a record of the reproduction in U felina. I think I read somewhere it is noted as probably sexual.

Andy Horton I have seen Urticina of 20 cm diameter at the Dove Laboratory Aquarium at Cullercoats, Newcastle-upon-Tyne. Rare colour schemes. And no warts on the column.

Andy Horton The group photograph shows the U felina I normally see with tubercules (if that is the right term?) on the column that attach gravel. But I do not know if this is definitive? I have got an older book (British Anthozoa by Dick Manuel) but my eyes get tired late at night.

Erling Svensen Erling Svensen 3 years at least for Cyanea, and more than 30 cm for eques. In Svalbard the armes are more slim than the ones we have here, and they looks quite different. I better go to sleep to, quite late in Norway now.

Andy Horton Dark even in Svalbard?

Erling Svensen 3 months with complete darkness and 3 months in summer with midnithg sun. Right now very nice with midnight sun and fine conditions. Even in Egersund it do not get dark - really dark in the nights.

Andy Horton Urticina felina

Becky Hitchin This seems a mix between a dahlia and a beadlet!

Becky Hitchin I thought they were on rocks mainly?

Becky Hitchin true true! it's just very different to where I'd exoected to see one down there, ours are mostly often white and stuck on wrecks / hard substrates rather than as per above

Erling Svensen This one must be Urticina felina. Ask Bernard Picton

Becky Hitchin Thanks Erling. I'd never realised how strange and different U. felina looks just as a column - incredible anemone!

Bernard Picton I think you are right Erling. It does look strange and hard to get a scale on it...

Becky Hitchin It was about 10-12cm across, in a sandy gully between chalk boulders

Becky Hitchin Sorry, Dawn, I should have said that at the start too

Andy Horton There are some very low equinoctial spring tides beginning today.

Becky Hitchin I'm all ready for a 5am start tomorrow!

Andy Horton I was going to go tonight, but from past experience March in Sussex is not very good. I have just cleaned the front glass of my aquarium.

Becky Hitchin I went out at lunchtime just for a walk and looked along a local strandline, found a live sea mouse, nudis and all sorts of unusual things (photos to come!)

Cathal McNaughton I hope they are low here too, great chance to see things usually out of reach.

David Hill Took your advice and went rockpooling this evening <a href="http://www.flickr.com/photos/natureseye/6821737734/" title="Dahlia Anemone (Urticina felina) by duckinwales, on Flickr"><img src="http://farm8.staticflickr.com/7204/6821737734_a455687997_m.jpg" width="240" height="180" alt="Dahlia Anemone (Urticina felina)"></a>

David Hill sorry - not got the hang of posting pictures yet!

David Hill Don't know if anyone can help with ID? www.flickr.com/photos/natureseye/6823178984/

Becky Hitchin Yep, it's sponge. I'd take a guess at Hymeniacidon purleve, but only due to that being what shape of sponge normally is in Kent. Sponges are very hard to identify, most of the time, without microscope!

Victoria Anne Coshall whats a sea mouse??

Becky Hitchin A sea mouse is *cool*. It's a strange looking worm - http://www.lancashiremcs.org.uk/gallery/sea_mouse.html - that only really looks like a worm underneath. On the top is a mass of iridescent hairs

Victoria Anne Coshall wow that definatly is cool

Becky Hitchin I love them, I've only ever found 2 on the shore. Utterly gorgeous

Victoria Anne Coshall are they irridescent out of the water?

Becky Hitchin yep, especially if you get them in the sunshine. hang on, hmmm, I have a photo ... http://www.flickr.com/photos/elegaer/6970620755/in/photostream - looking a bit bedraggled there, but you can see the iridescent bits at the bottom
