Ron Silver Where was this photo taken was there any Halimeda green algae in the area? I can just make out the Ascidian, Didemnum molle in the background.

Ellen Cuylaerts Really love this picture, I wanna see it again and again!

Iyad Suleyman Thanks Ron and Ellen for comments. @ Ron: This picture was taken in Manado-Indonesia. yes it was there also Halimeda green algae.

William EL Lim Damar Island, Indonesia.

Ron Silver Didemnum molle. An attractive tunicate.

Esther Chan A kind of soft coral in beautiful Lime Green color Bunaken, Indonesia

Ron Silver After closer inspection and more thought, appears to be a tunicate (ascidian), Didemnum molle

Ryanskiy Andrey ID this flatworm, please! Lembeh, 15 mm

Ron Silver Here's a photo from the Philippines by Jim Anderson of the same flatworm: http://www.nudibranch.org/Flatworms/philippines/html/Unidentified-04.html

Boomer William Wing Ascidiophilla sp. on Didemnum molle http://blog.livedoor.jp/akane__satetu/archives/cat_50045189.html

Boomer William Wing ^way down near the bottom of the page.

Ron Silver Thanx, Boomer

Ryanskiy Andrey Thank you all, livedoor blog link is very interesting. I was trying to find one more confirmation. Looks like it is the only one picture with a worm like this one, identified as Ascidiophilla.

Boomer William Wing That was all I could find Ryanskiy Andrey par the small pic of one in the book Marine Flatworms of the World but a different species. The name does tell you something "ascid " is from Ascidians, which is were these species are only found.

Ryanskiy Andrey Thank you, Boomer William Wing, I have to look on this book once more (I have it in Kindle-iPad version)

Boomer William Wing You will find that pic of the actually flatworm is rather small. I will run another check for you tomorrow to see if I can find another of the same. One must remember many marine creatures are un-ID.

Ryanskiy Andrey I see picture in the book, looks like it is our suspected flatworm - I attach it - and in the book it is Ascidiophilla alba

Ryanskiy Andrey But all other pics in the web of Ascidiophilla alba are showing another creature - now it is my picture. May be both are just Ascidiophilla sp1,2 :)

Boomer William Wing Yes, the A alba does not look like yours. It is hard to tell in the book pic. So, the best we can say is yours is Ascidiophilla sp,

Ryanskiy Andrey I agree, we are more or less sure they are Ascidiophilla, let the one with specles be Ascidiophilla alba. And I like the idiom from marine life ID books - "Identification tentative" :)

Ryanskiy Andrey But Alba is White in Latin - and the Ascidiophilla on my 1st picture is really White!

Boomer William Wing Yes, here is the full description of A alba, which fits yours and not the others. It may be the other A alba on the net are incorrectly ID and you have the real deal. But the other issue is A alba is only ID from the Great Barrier Reef but Ron's pics which are no doubt the same as yours are the same and in the Phillipines. And the pic in the PDF also sucks. Then there is the Ascidians D molle. It is found through the Indo. So, we are good there. http://qm.qld.gov.au/~/media/Documents/QM/About%20Us/Publications/Memoirs%20-%20Nature/N48-1/n48-1-newman.pdf

Ryanskiy Andrey Boomer William Wing, thank you for description. Looks really like our worm (I mean 1st picture - White one) The only problem is host - our's is not D.molle but Nephtheis thompsoni

Boomer William Wing Yes it is, never even thought to check it out let alone even really look at it. I should no better Ascidians are my favorite group. Guess I was tunnel vision on the flatworm. I will see what I can find for us on it. With that said, there is no ruling that A alba is found ONLY on D molle par maybe the GBR clan. And with that said, comparing the two ascidians, being alike, is like comparing apples to oranges. Many symbionts are very, very picky, to the point where it has to be the exact species. But I do not see that here with this flatworm.

Boomer William Wing You give me Nephtheus thompsoni and in 5 sec I find this :( http://www.flickr.com/photos/brianmayes/8323407410/

Ryanskiy Andrey Ues, I saw this photo too, I took tunicate's name from it :) (By the way, I liked very much "Shells" set of this photographer)

Boomer William Wing And one more note. That Ascidian on the Japanese website is NOT a D a Molle at all but a lollipop Ascidian like yours and probably a Nephtheus sp.

Ryanskiy Andrey Ues, looks like our A.alba is rather unscrupulous in hosts ))

Boomer William Wing The flatworm on my link above on the Nephtheis that looks just like yours and Ron's is Cycloporus sp not A alba.

Boomer William Wing Just checking, was your Ascidian a stalked Ascidian like this http://upload.wikimedia.org/wikipedia/commons/2/24/Oxycorynia_fascicularis_(Tunicates).jpg

Boomer William Wing This is D molle http://www.ryanphotographic.com/images/JPEGS/Didemnum%20molle.jpg

Ryanskiy Andrey It was a colonial tunicate - with common stem I think - here is uncropped picture

Ron Silver Appears to be Clavelina sp.

Ilan Lubitz any idea we be appreciated

Arne Kuilman The green is Didemnum molle and the other a colonial ascidian. Looks interesting.

Arne Kuilman Like Botryllus schlosseri

Ilan Lubitz tnx Arne Kuilman tnx so practically both are sea squirt ? ;-)

Arne Kuilman Yep, but the starry one is uncommon and a colony of many smaller ones.
