Securiflustra securifrons

(Pallas, 1766)


Klas Malmberg Aquatilis Found this Crimora papillata last year in Swedish waters and it´s new by us. Has anybody found it i Norway?

Erling Svensen .... and the sice? What does it eat? I hve never seen it (as I know).

João Pedro Silva Not very common here but we see it now and then. Last summer in Algarve there were lots of them.

Claire Goodwin It's normally on the bryozoans Chartella papyracea, Flustra foliacea or Securiflustra securifrons. It's a southern species (from Med but I'm not certain of its Northern limits - it is restricted to south and west of Britain and Ireland) but might be increasing with climate change - one of a few things that are increasing in abundance/widening distribution in our study area (Northern Ireland). I'd think your Swedish record would be interesting Klas - but maybe other people on here can say if it is a new record.

Klas Malmberg Aquatilis Size around 2 cm and it was feeding on Flustra. Found it on "Väderöarna", 25 meters, at an exposed area. Cheching whith Natural history museums has said that this was the first finding in Sweden, but I wouldn´t be surprised if some underwaterphotographer has pictures of it. And if we see it here I think it´s likely to be around Norway too.

Bernard Picton Deirdre, I was very excited when I first found it in the west coast of Ireland so it's interesting to hear that you have it commonly in Dublin Bay. When we did the BioMar survey of Ireland (1993-96) we recorded it from scattered sites all round the west coast. As Claire says we've found it quite frequently in Northern Ireland in the last 7 years, but in the 1980's we only found it once, so I think it has become more common. Jim Anderson found it in Scotland in 2008 (Sea Slug Forum), but Sweden is quite a surprise for me, Klas.

João Pedro Silva Not sure if this photo is useful to identify the bryozoan it's feeding on: http://www.flickr.com/photos/jpsilva1971/5830668102/

Christian Skauge Hi guys, I was wondering if anyone could say what species or at least genus this might be? I have it down as a Crisia sp. Would be good to know, as I plan to use the image in a book... :-)

Bernard Picton A Bugula?

Christian Skauge Sorry, completely forgot data in my haste to be the first to post here :-) Found off the coast of Haugesund, Norwegian west coast, 31.07.2004. Depth approaching 20 meters as far as I can recall.

Bernard Picton We need Jo Porter to find some helpers, so be patient.

Christian Skauge No rush, they're probably still there :-)

Joanne Porter I'd agree with Bernard, definitely a Bugula.

Bernard Picton I was hoping you'd say which one Jo.

Bernard Picton Need a closer picture?

Christian Skauge I can enlarge if necessary... Hmm genus Bugula... the nudi in question (Diaphorodoris luteocincta) doesn't eat those, apparently... *dammit, must find new image for book*

Bernard Picton It might eat those, never trust anything written in a book.

Bernard Picton Crisia is similar looking, but only a single row of zooids I think? Several sorts here.

Christian Skauge True, they'll probbaly eat anything if hungry enough ;-) But since I'm not dwelving too deep into the biology stuff (I leave that to you!) I'll have to sift through my images to find something that matches my sources... Thanks, this is actually a great help!

Erling Svensen Are you sure that this not might be Securiflustra securifrons? I have a feeling for this one.... ;-)

Liz Morris Looks like Bugula flabellata to me, but I'm no expert. Id be interested to see the answer

Leandro Vieira Looks like Bugula flabellata or Bugula fulva.
