Jeremy Pierce Going through some old pics from June 2011 at the Breakwater Fort, Plymouth.....are these anemones or small/young spiral Fan worms or ??? Looked through all my books with no luck. I would say, judging by the Clavelina in the picture that they are no more than 2cm tall!! Cheers JAP :-)

Jeremy Pierce Thank you!!

Frances Dipper Yes I agree. Lovely things.

Joanne Porter another one of those amazing creatures that have a lophophore :)

George Brown Does anything have a particular appetite for Phoronis? Anything we can look out for?

David Kipling Some details here on predators, and it's lophophore. http://linnaeus.zoology.gla.ac.uk/~rpage/wiki/index.php/Phoronis_hippocrepia

David Kipling *its

George Brown Thanks David.

Erling Svensen Yes, Phoronis hippocrepia. In Norway I find them only in limestone rocks where they drill holes. There is another species, Phoronis ovalis, that have more oval lophophore and only 20 tentacles.

Erling Svensen David, I can see from your link that this species should not be abundant in Norway - but it is quite common in the South Norway.

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. http://www.flickr.com/photos/jpsilva1971/7256479120/

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 :) http://www.flickr.com/photos/jpsilva1971/5199223378/

David Kipling Yes, we had some Phoronis hippocrepia yesterday Kerry ;)

João Pedro Silva Phoronis australis is occasionally also found here, usually associated with Cerianthus membranaceus: https://www.facebook.com/photo.php?fbid=635444863147974&set=a.635444376481356.1073741836.100000473971278&type=3&theater

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. http://www.biblestudytools.com/lexicons/greek/nas/kampto.html

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