Sonja Ooms Ringed chromodoris (chromodoris annulata) that thinks it is a clam. They are quite common here. I found it at a depth of about 8m and it was about 5 cm big. Beirut, Lebanon - 02/11/2013

Dani Barchana Thanks Ron Silver , I did not know that.

Ron Silver With genetic testing, changes to scientific classification and/or names are coming fast and furious!

Mark Watts Sweet.

Natalia Rifai Great.... See how gorgeous they are? They also love currents. Actually Lebanon are the only waters where I have seen them in the mediterinian up till now.

João Pedro Silva One of the lessepsian migrants coming into the Mediterranean. I guess some more will come. Hope indigenous species are not affected.

Sonja Ooms So far I have only seen this one and an ornate elysia

João Pedro Silva Sandrine Bielecki's "Des Limaces de Reve" shows at least 8 species of opisthobranchs in the Mediterranean which are native to the Indian ocean. It doesn't include Elysia ornata, though. Are you sure of the identification? http://www.deslimacesdereve.com/

Natalia Rifai Don't worry, I have seen lots!

Natalia Rifai All is ok! Those waters are full of excitement, love and beauty. Last year I was interviewed there by a local newspaper and we talked on the matter as well. I believe we are living and witnessing an amazing evolution and adaption in those waters. Imagine a divers emotions once seeing a lion fish at a depth of 30 meters in the mediterinian. Last year, one was spotted at AUB, very close to the site where this nudi was photographed. This summer, more than 3 lion-fish in one dive where spotted around 15 kms away. Who said globalization is only a humanistic characteristic.

João Pedro Silva I'm afraid I don't share your enthusiasm for exotic species. History has shown the introduction of invasive species is often a really bad idea.

Natalia Rifai Sonja Ooms, as I have already said told you back at the dive center all those nudis start to blossom in surge and currents. That's why during bad weather the waters start to blossom particularly during winter.

Sonja Ooms @ João Pedro Silva: E. ornata is very variable in color and markings and found circumtropically (tks Ron Silver). I'm sure about my ID

João Pedro Silva Some species have even wider distributions.... but not this one. The question is not the validity of your ID: it's an ecological issue which seems to be escaping some.

Dani Barchana Chromodoris annulata _ Red Sea, Israel Canon PowerShot G12 Flash Used Sea&SEA YS-01 Focal Length 13.8 mm Exposure Time 1/500 sec Aperture f/8 ISO Equivalent 80

Ron Silver Dani, could these nudis be Risbecia pulchella? C. annulata is very similar, but has large purple circles on the dorsal surface.

Dani Barchana Ron Silver I think you are right, I stand corrected, Thanks.

Ron Silver No problem. Some would say I'm a bit anal about IDs. Thanx for posting your photos. :-D

Dani Barchana I appreciate the correct ID, I wouldn't like to post mistakes,as UI have an album of Nudis, I also corrected it there ( http://www.pbase.com/dani_barchana/sea_slugs ) thank you (Y)

Ron Silver Thanx again. I have been quite surprised at the reactions from some when I have suggested an alternate ID. :-(

Dani Barchana Well, it is the Nudis Ego, not mine :-P :-D

Dani Barchana BTW, Ron Silver , if you find mistakes in the Pbase Album above, fill free to comment

Ron Silver I quickly looked and see you do have some great photos of C. annulata from the Med and just one shot of R. pulchella from the Red Sea. Nice compilation of nudis.

Dani Barchana Thanks, The Annulatas are invaders from the red sea to the Mediterranean sea, it is called Lessepsian migration (after Ferdinand de Lesseps the Suez canal engineer) - But I guess you know that.....

Ron Silver Invasive Biology 401 as I recall, but it was a l-o-n-g time ago! Thanx.

Bunnee Gamboa-Santos ID please. Twin Rocks, Anilao. Canon G9

Ashley Missen Great Picture Do you have any other ones for different angles

Bunnee Gamboa-Santos I do not have any other ones. Is this a chromodoris annulata?

Ashley Missen Probably not as they have purple edging and the only other purple is 2 defined rings on the top of the mantle - hence why I asked about any other pictures as this angle is hard to ID from - Most likely risbecia sp. see link - cheers Ash http://www.nudipixel.net/photo/00026544/location/anilao/

Bunnee Gamboa-Santos Thank you. Yes, it does look like risbecia sp.
