Pentapora foliacea

Mickey Charteris Greeting fellow nudi-lovers. Anyone out there able to put an ID on this one, even a genus? Only been spotted on sandy slopes, Roatan, Bay Islands, Honduras. Note the white cross between the rhinophores. Thanks

Jacqueline Freeman WoW! Beautiful!

João Pedro Silva Madrella sp.

Vinicius Padula Madrella sp. - There is no Madrella described from the W.Atlantic and much probably this is an undescribed species.

Mickey Charteris Thanks, actually taken by my friend Rino Jackson, his find.

João Pedro Silva This is quite a find. Which bryozoans did you find around it (if any...)?

Mickey Charteris Can't find it ID's anywhere, so yes we were thinking a new species, anyone seen anything like it before in W Atlantic?

Mickey Charteris Are they commensal with bryozoans? Don't know.

Vinicius Padula A few months ago we received photos also from Honduras. Would be good if you can collect 2-3 specimens for study.

Mickey Charteris If Rino finds another one, where can it be sent to be described?

João Pedro Silva From the Atlantic I only know of Madrella aurantiaca... but that's E Atlantic and Mediterranean... and even then, rare. Madrella aurantiaca apparently feeds on Pentapora foliacea inside which it spends most of the time.

Mickey Charteris Will be on the lookout, thanks. Where to send them?

Vinicius Padula I will send you a message.

Mickey Charteris Cheers, Vinicius. Joao, we don't get Pentapora foliacea here, I think, but will look closer into similar Bryozoans now.

Carol D Cox I hope I will see some when I visit Roatan in December!

João Pedro Silva Any idea on what this might be? <1cm long, inside a colony of Pentapora foliacea, Berlengas Portugal, ~27m deep, water temp. 18ºC. Sorry for the bad quality crop. Shot it because it looked like a small Haliotis tuberculata but lighting the photo was hard so after this shot I went looking for other subjects.

Marco Faasse Maybe a pectinid bivalve with a sponge on the upper valve?

Erling Svensen Yes Marco, looks like......

Věra Trávníčková what is the orange stuff down below nudibranch?

João Pedro Silva Looks a bit like Pentapora foliacea.

Věra Trávníčková Bryozoa?

Věra Trávníčková is it the same???

João Pedro Silva Yes, that's Pentapora foliacea, a bryozoan (or ectoproct).

María Eugenia Suárez Věra Trávníčková they are the future nudibranch, they are eggs.

João Pedro Silva That's the egg mass to the right, not the bryozoan underneath.

Věra Trávníčková I know :-)

Věra Trávníčková Clever one, isn!t it? He knows that his eggs and Pentapora are similarly shaped :-D!!!

João Pedro Silva Although I think it's the first time I see it spawning on P. foliacea :) The egg masses are very similar to those of Platydoris argo, too. And colour can vary a lot. http://www.flickr.com/photos/jpsilva1971/7827002902/in/set-72157626720024632

João Pedro Silva Here's an example of Platydoris argo with bright orange spawn: http://www.flickr.com/photos/jpsilva1971/7816743654/in/set-72157626720024632
