Francesco TuranoCerianthus membranaceus longevo...
Tullio Foti .................come prima...............silenzio,anzi mi dedico ai compiti per casa ,ricerca del bianco e nero !ciao Francesco ,ad maiora non si può ! dopo questi spettacoli,ma attenzione che un super critico killer in costante agguato potrebbe trovare il pelo nell'uovo di seppia !!!????
Alessandro Diotallevi Longevo quanto ? :-))))))
Angelo Mojetta Ciao Francesco, ti ho inviato un email. L'hai vista?
Angelo
Ilse Merz WOW!
Alessandro Diotallevi Nel senso da quanto lo conosci, da quanto fotografi questo esemplare ? :-))))
Francesco Turano Alessandro: io lo fotografo da sempre, ma dai racconti di chi mi ha preceduto nulla esclude che questi animali potrebbero avere quasi un secolo...

Stuart Pearce Tube Anemone (Cerianthus membranaceus)...
Altinkum, Turkey 2008.
Michael Sterken I think I have seen a similar species. But what I saw was very dark, and much smaller. The tentacles seemed to have suckers on them like an octopus. They were constantly wiggling. one that I saw was under a rock so I could not get a close pic, and then the crazy DM in St. Lucia actually picked one up to show, but I could not get near him to photograph. it seemed to be one organism. Do you know the species?
Michael Sterken this is a photo my dive buddy shot - SeaLife camera
Stuart Pearce Is this it? http://stevenwsmeltzer.photoshelter.com/gallery-image/Coral-Reefs/G00007HdqcXifCa4/I0000IPqTBNf2Kl8
Michael Sterken no. the "branches" were smooth except for the suckers, and wiggled around very freely. not rigid at all. to me, it looked more like an animal rather than coral. I actually would have been afraid to touch it for fear of a sting.
Stuart Pearce Will have a better look later Michael, need to go out now :)
Ron Silver Giant Basket Star, Astrophyton muricatum (juvenile)
Stuart Pearce Thanks Ron, here is an image http://simonsen.photoshelter.com/image/I00002fHcZmdIHdA
Michael Sterken That's it! I could not find it, but I was looking at the anemone family. Thanks! (kind of a funny side-note: I was at a local aquarium where they let the kids touch various creatures. My daughter called the starfish a starfish, but they vehemently corrected her - they said "that is not a fish, so we have renamed it "Sea Star". I told them they would have about as much luck as the USA did trying to convert to the metric system.) thanks Ron Silver & Stuart Pearce.
Vasco Ferreira Anyone knows this little Polychaeta? It´s very small, notice the Jewel anemone in the lower part of the photo. Thanks.
Vasco Ferreira A Phoronida... Thanks Dawn, i was kinda lost here!
João Pedro Silva These are very common here in Portugal: http://www.flickr.com/photos/49844432@N08/8872398378/
João Pedro Silva But we also have Phoronis australis usually next to Cerianthus membranaceus:

Vasco Ferreira I must have been distracted João! First time i saw them, here in North Portugal Marine Park (i´m always looking at the fishes tough).
João Pedro Silva When I'm asked how I spot small animals I usually say it's all a matter of "tuning". I'm usually tuned to small stuff so I miss the big stuff :)
Erling Svensen Very comon in the fjords in Norway too.
David Kipling Lovely little crown of tentacles - is this a hydroid? ~ 10-12m, Pembrokeshire, tideswept reef.
João Pedro Silva Or Entoprocta?
David Kipling How would I tell the difference?
Marco Faasse João Pedro Silva is correct, these are certainly Entprocta. Pedicellina sp.
David Kipling Thanks! I hope Bernard's hydroid course will include "stuff that sort-of looks like a hydroid but isn't" ;)
Marco Faasse The shape of body and tentacle crown is characteristic.
João Pedro Silva At first the crown looked more similar to a bryozoan's but the long stalk hinted to Entoprocta. I know very little about them but the association of Trapania spp. with these animals triggered my attention.

Kerry Lewis Oh god, that's a whole new phylum! I'm ignoring this post.
João Pedro Silva There are more phyla which are usually overlooked :)

David Kipling Yes, we had some Phoronis hippocrepia yesterday Kerry ;)
João Pedro SilvaPhoronis australis is occasionally also found here, usually associated with Cerianthus membranaceus:

Liz Morris These are the best Enctoproct photos I've seen... but get them a lot in my petri dish when in the Cleddau. Nice :)
Cynthia D. Trowbridge David Kipling, theoretically you should be able see both the mouth and anus within the crown of tentacles (hence ento-procta); hydroids just have a mouth and no anus; ectoprocts have anus outside circle of tentacles....so it all depends on whether you can find an anus...
Marco Faasse And for the less anus-oriented people: the stalk of entoprocts is regularly bent to the substrate, probably some stimulation will help.
David Kipling So if I get this right: entoprocta (poo inside tentacles), ectoprocta (poo outside tentacles), and hydroids ... er how do they get away with not having an anus, do they have a funny diet or something?
Marco Faasse In Dutch: mondje=kontje (mouth=anus). Not exactly to be jealous of.
David Kipling Entoprocta aka kamptozoa ... "bowing animals" apparently, good way to remember the bent bit Marco! This is why a classical education is (or in my case, would have been ...) useful.

Marco Faasse There you go ... I never knew what kamptozoa meant. How a lack of biblical education makes one a handicapped person ...
