Marcus Scheunemann Location: Hurghada/Egypt, Depth: 10 m, Size: 7 mm. Any ideas?
Ron Silver Could be a juvenile Ssidegill slug, Pleurobranchus peroni?
Lindz Warren Unliely to be a Pleurobranchus - rhinophores are clubs not rolled and not in right position. Also it looks as if there is a dorsal gill plume but it is fully retracted in this photo.
Marli Wakeling Is this your only photo, Marcus Scheunemann? I was wondering if you have one showing the gills?
Marcus Scheunemann Hey Marli Wakeling sorry, I was busy with travelling. There is another macro picture I will support you with, but just after one more day. Thanks for all your help so far!
Marcus Scheunemann Another photo, but the gills are retrcted as well ... what a pitty. I watched this one (by the way, night dive) for some minutes (~10 minutes) and never were able to observe gills at all.
Marli Wakeling I think it may be a Rostanga sp.
Sven Kahlbrock Rostanga sound familiar to me, found one before too, but can´t find pic atm ;-)
Marcus Scheunemann If you have another pic, maybe it becomes clearer
Kieren Curry Hey Guys about half way through the is an orange and brown Nudi anybody can to identify? Enjoy!
Gary Cobb The first Nudibranch at 1.23 is Syphnota geographica, the one at 1.34 (very short footage) is Plocamopherus imperialis and the one at 1.36 is Pleurobranchus peronii.
Kieren Curry wow that was fast Thankxs Gary :)
Gary Cobb Only too glad to help!
Ashley Missen I agree with Gary
Kieren Curry cheers Ash! Will be filming more Nudis soon :)
Nick Hope Thanks Marli Wakeling. But then it's spelt with 1 i in plenty of "authoratitive" places too. Can WoRMS be taken as THE authority on this type of issue?
Jim Anderson I tend to follow WORMS as the authority ....... but!!!
Marli Wakeling I see what you mean. One needs to establish whether Peron is male or female. That will be the definitive answer.
Nick Hope I'll trot off a quick email to Georges Cuvier. I wonder if he's on facebook...
Patrik Good Probably a juvenile Pleurobranchus peronii. Goldcoast Seaway, 29/7/2012, depth 3m, size 11mm. It is good to have this species back at the Seaway. It had gone for a couple of months. Now it is back in all development stages, sizes and colours. This individual was found in between rocks, clinging to the ceiling.
Ryan Pearson Hey all, I'm new to this... thought you all could probably ID a few of these faster than I could :P
Gary Cobb I can't comment on the photos (Doh!) so here I go again....pic 1 and 10 Chromodoris verrieri (Cross, 1875), Pic 3 and 7 and 8 Pleurobranchus peronii Cuvier, 1804, pic 11 correct, pic 15 Syphonota geographica (Adams & Reeve, 1850), pic 16 Chromodoris cf. reticulata or as some say Chromodoris tinctoria but that species has white gills, pic 17 Hydatina physics (Linnaeus, 1758)
