This is the animal I am calling Flabellina sp. 1 . It has a very distinctive colour pattern.

I found these in the Egyptian Red Sea. I wondered if they are Flabellina exoptata, but the body is not that small and the typical rhinophores are missing. Do you have any idea what it is?

I think this specimen is an undescribed species of Flabellina, and it looks similar to the Flabellina sp. 1 in the list.

I agree that this is probably Flabellina sp. 1

I can't find this one in any of my books, but to me it looks like Flabellina sp.1, what do you think?

Yes this is the animal I have been calling Flabellina sp.1, however I am leaning towards the idea Philip Cromwell and others suggested 5 years ago [#8281] that this is Cuthona sibogae. A look at the radular teeth would quickly solve the puzzle.
Your lower photo though has a strange feature. In the inset I have included you will see a pair of short tentacles at the front of the foot. These are the sort of tentacular foot corners you would find in a species of Flabellina, but species of Cuthona don't have them. Perhaps there is a cuthonid and a flabellinid with very similar colour patterns?

This animal seems to fit Flabellina exoptata, but I am not convinced. There are loads of these in the Northern Red Sea, mainly around 30, 40 metres and living and feeding on hydroids. Is this a colour variation of F. exoptata or is it another species?
Locality: Northern Red Sea, El Gouna, 25 to 40 with exeptions, Egypt, Red Sea, 2006, 2007, Deeper, on Hydroids, shady areas like in and around wrecks. Length: 2 to 5 cm. Photographer: Darja Tjioe.

You were right to be doubtful. F. exoptata has quite distinctive papillate orange rhinophores while in your photo alongside, you can see they are smooth and purple. This is a species I am calling Flabellina sp.1. At one stage I thought it might be a form of F. rubrolineata. which sometimes lacks red lines, but again the rhinophores are wrong.

Could you please help me with the identification of this nudibranch. To me it looks like Flabellina sp. 1.

Yes this looks like the animal I have called Flabellina sp. 1. I wobndered if it was a Cuthona, but your photos show it has tentacular anterior foot corners, which are not found in that genus, so I think we can be pretty certain that it is a species of Flabellina, but it appears to be an unnamed species.

I'm not too sure about this one. It looks a bit like the one which I have called Flabellina sp. 1 , but the photo is a bit unclear.

I just had a look at the Forum and saw your posting of OWN67 - Flabellina sp. This is in fact a different specimen from the one sent to you by Adam Powell. OWN67 was found in 14.1 m of water along the island of Kaledupa which is opposite Pulau Hoga where the Operation Wallacea marine base is
located and is also a long way from Komodo where Adam found 'his'.
All the best

Thanks for the confirmation. I had realised the two specimens were different - just quite a coincidence that the two messages arrived almost simultaneously. I have more of your interesting material almost ready to put on the Forum.

Here is a photo (by Adam Powell) and a sketch (by Richard Smith) of OWN67. Dave Behrens has seen the photo and suggested that it
might be a new Flabellina. Have you seen one like this before? Length: 9-10 mm. Found at a depth of 14.1 m on a smooth black sponge with randomly dispersed oscula and it appeared to be feeding on it. The rhinophores are papillate, non-retractile and held high with a small eye spot at the base. Oral tentacles 'frosted' with magenta. The notum is a frosted white with magenta tip to the tail. Two thirds of the cerata from the base are a lighter magenta, followed by a band of pale orange, a band of magenta and
orange tips. The foot is pale orange.

I'm pretty sure this is another specimen of the species Adam Powell just sent a message about. As I said before it does look like an undescribed species of Flabellina.

I'M ADAM POWELL PHOTOGRAPHER WITH OPERATION WALLACEA. I RECENTLY SPOTTED THIS CRITTER WHILE AWAY ON A BALI TO DARWIN CHARTER ONBOARD MV EMPRESS IN THE KOMODO AREA. ANY IDEAS? IT APPEARS FAMILIAR BUT COULDN'T SPOT IT IN OUR LITERATURE, A PAIR WERE FOUND ON A HYDROID . WE MANAGED TO ID ABOUT 50 SPECIES ON THE TRIP 3 OF WHICH ARE A PUZZLE ,INCLUDING THIS ONE , ALSO A NEMBROTHA FOUND BY PETE VOGT WHICH HE'S FORWARDING AND A HYPSELODORIS ? WHICH I,VE SENT THE IMAGES BACK TO THE UK AND WILL SEND ON ASAP.
MANY THANKS FOR THE EXCELLENT SLUG FORUM

Thanks for the message. Peter Vogt's Nembrotha message has arrived and solved. Unfortunately I can't be so quick at identifying your species, which is probably, as you suggest, a species of Flabellina. If you can send a larger scan it might be possible to see some more details, like shape of the rhinophores etc. Look forward to the Hypselodoris pics.
Anyone else got ideas on this species?
