Tubularia larynx

David Fenwick Snr Just found what I think are three 2mm Catriona gymnota on a small sample of Tubularia larynx at Sennen Cove, Cornwall, 25.04.13, in an underboulder pool on the lowershore. Can someone confirm the species please.

Peter H van Bragt Hello David, most likely indeed C. gymnota. What's in a name, I believe the current name should be Cuthona gymnota.

David Fenwick Snr Thanks Peter, I tend to follow WoRMS and Conch. Soc. for naming things, this time they don't agree.

Ian Smith Hi Dave, glad to see the hydroid sampling is bringing in results. I'm stuck with the names loaded onto the Conch Soc website when I do descriptions. I've asked for WoRMS to be adopted, but the Society only updates periodically. To try to redress this I put a link to WoRMS under "current taxonomy" on each account. When the title names are eventually updated, it will look like the content of accounts is clinging to old names. My advice is to go with WoRMS. A rose by any name would smell so sweet.

David Fenwick Snr Will send in the record under the WoRMS name just in case it helps. More hydroids and sea mats to go through later Ian.

Bernard Picton Don't worry about the current genus name. Cuthona will be split soon. Latest sequence data suggests that Calma is a Cuthona, so that puts a family inside the genus...

Cynthia D. Trowbridge egad...as bad as sacos...

Erling Svensen Any one that can say something about this hydroid?

Simon Parker Looks like Tubularia indivisa to me.

Erling Svensen Tubularia indivisa is the "big" red one between the small one. It is the small one (close up) that I am interested in.

Simon Parker From the relative scales I'd say the smaller one is Tubularia laryx.

Bernard Picton It doesn't look like Tubularia larynx, nor anything else I've ever seen. Where are you Erling?

Erling Svensen I am out of Bodø close to Lofoten in north Norway on a scientific cruise with Bjørn Gulliksen and many others. Diving from a ship is very nice :-)

Marco Faasse Probably Eudendrium. One ring of tentacles, funnel-shaped proboscis ans shape of the hydranth suggest this genus.

Erling Svensen I agree, Marco. What about Eudendrium annulatum?

Marco Faasse I don't know E. annulatum Erling Svensen, is it a northern species?

Erling Svensen Yes, I think so. I know that Bernard have picture on his Habitas pages.

Marco Faasse Yes Erling Svensen, E. annulatum and E. arbuscula seem likely candidates. Schuchert (2012, Synopsis British Fauna) has a key: E. annulatum is more tree-like, sometimes with bark-like covering of the main stem.

Bernard Picton Can you collect some? Eudendrium arbuscula is tree-like with the polyps on short branches. Peter Schuchert (Museum Geneva) recently revised the European Eudendrium species.

Brendan Oonk Nice pics. By the way: WoRMS uses the name Ectopleura larynx

Becky Hitchin Ectopleura? eeepp!
