Cuthona concinna

Arie Vreugdenhil Cuthona concinna at 7m at Zeelandbrug Oosterschelde 10-15mm large animal

Arie Vreugdenhil Cuthona concinna, at 7m, at Zeelandbrug Oosterschelde, temp, 3 degrees Celsius Animal was about 10-15mm

Henk van Dijk Erg mooi!!!!!!

Liz Morris Can somebody please tell me whether this is Cuthona cocinna please? It's not been recorded in our area since 1996 according to NBN Gateway so I'd like to be sure! It will be a nice spot if it is, but I'm not holding my breath!

Bernard Picton Yes, Liz, this is Cuthona concinna and the normal food for it, Serrtularia argentea..

Liz Morris Hurrah!! Thank you Bernard :) It was teaming with Sertularia as usual and there were a few of this little critter around. Brilliant. Worth a record then.

Paula Lightfoot Maybe Coryphella? Not sure if the photo has enough detail for an ID and it's the only shot I got...

David Kipling Don't think so - from this angle the cerata look too stubby (as opposed to pointy-ended). A Cuthona perhaps?

Peter H van Bragt Cuthona concinna most likely! Cheers Peter H van Bragt

Paula Lightfoot Thank you very much. That sounds likely, I've seen Cuthona concinna on the east coast before, that was on silty hydroids too.

Julia Nunn i also would guess Cuthona concinna

Klas Malmberg Aquatilis At Väderöarna in Sweden we right now have an explotion of Cuthona concinna. So could somebody tell me what to use; cuthona or trinchesia?

Bernard Picton I think it is better for stability to use Cuthona until we get a real (DNA) tree for these Tergipedidae. Bill Rudman argued for this, there should probably be several genera. I'm not certain that Cuthona nana and Precuthona peachii are really the same thing, which would make things even more complicated. Cuthona nana was described from the North Sea coast of England if I remember rightly, under a stone. It would be great if specimens matching that description could be found by someone in the Northern part of our area (Norway, Sweden, Netherlands??). http://www.seaslugforum.net/showall/cuthonadisc

Jørn Ari Is this a Cuthona concinna or a Cuthona nana? Size 8 mm, from Denmark

Bernard Picton Cuthona concinna, Jorn. The digestive gland inside the cerata is usually this grey colour.

Jørn Ari Thanks Bernard

Jørn Ari Thanks Bernard

Bernard Picton Cuthona concinna. I've only ever seen two or three of these at one time.

Klas Malmberg Aquatilis I had a wonderful dive today att Väderöarna and collected 10 Cuthona concinna to our natural history museum today. I could have collected hundreds of them if I wanted, and this is quite normal in mars at väderöarna in Sweden. It was a lovely day and we counted to 20 different species on two dives so we were really happy. Pictures will follow tomorrow.
