Olive Chan Beautiful !

Gary Cobb When species names are written only the genus (first part of the name) is capped.

Mario Smid A flabellina? What do u think? Bali, 16m 15-25mm long... By the way, is it ok to post that much here? I'm on holiday now and try to identify the nudis as soon as possible, because back home I don't have the time ;) Thank u soo much!

Vie Panyarachun I'm tempted to say Flabellina bilas but this one lacks the "medial blue diamond shaped marking"...

Mario Smid That was my first guess too, but the cerata seem to have a different shape and color and the tops were transparent. I think Also the oral tentacles are different.

Arne Kuilman Very common nudibranch (IMO). Flabellina bilas

Mario Smid Ok thank you ;)

Scott White Sogod Bay sth Leyte ID please

Lindz Warren Probably Flabellina bilas (Gosliner & Willan, 1991)

Gary Cobb Yes it is!

Scott White Thanks

Scott White Sogod Bay sth Leyte ID please

Gary Cobb Flabellina bilas

Scott White Thankyou

Chris Spence Not sure of this one either. Closet I could find was either Cratena or Trtonia or Baeolidia sp?

Chris Spence That should have been Tritonia sp. Milne Bay PNG.

Gary Cobb Easy! This is Flabellina bilas (Gosliner & Willan, 1991)

Chris Spence Could have been more wrong. Wow looking at your specimin in your app it is far more flamboyant probably why I missed it. But the white markings are the same looking closely! Thanks Gary Cobb!

Gary Cobb Its the two white bands on the cerata that give it away!

Chris Spence Got it!

Chris Bergermann found today at Shaab Umm Gamar / hurghada RedSea about 10m / length ca 35mm

Mario Smid Also Bali, around 6 m depth, very tiny ;) Thank u!

Blogie Robillo I guess it's a nudibranch. Do you have a closer shot?

Mario Smid Yes, its a nudie, but i cannot find it in my books. I'll post a 100% crop. Thx

Ruby Ann Balio Looks like a one of the Eubranchus sp.

Mario Smid Thx a lot Ruby!

João Pedro Silva Never tried to bribe my models but will do this week.

João Pedro Silva Just checked the exchange rate and found our nudibranchs may be a lot more expensive to bribe. No wonder we only find ~120 species here.

Mario Smid ;)

João Pedro Silva The close up shows ringed rhinophores so it's not Eubranchus (in spite of the swollen cerata) nor Trinchesia.

Marli Wakeling Eubranchus mandapamensis; it has projections on the rhinophores.

João Pedro Silva These don't seem the somewhat irregular projections on the rhinophores typical of E. mandapamensis, Marli Wakeling. In the closeup they look a lot more like rings/lamellae.

Arne Kuilman Why not a very tiny / young Flabellina bilas? Colors match perfectly, but it's hard to tall when they're so small.

Marli Wakeling João Pedro Silva, I see what you mean. Interesting.

Scott White Sth Leyte any ID

Scott White Very small 10cm or so

Sven Kahlbrock could be a form off Flabellina bilas

Peter Fiechter I do only knwo the german Name: Purpurner Drache

Shane Siers Sorry, Peter Fiechter, what you're thinking of is Pteraeolidia ianthina, the "Dragon Nudibranch"...I agree with Sven, looks like Flabellina bilas.

Scott White Yeah I thought a type of flabellina,,

Scott White Oppps yes mm

Sven Kahlbrock Looks similar to F. bilas from the red sea, but much more light color
