Notes compiled from Brunckhorst, 1993:
External features which distinguish F. rueppelii from other species of Fryeria include its white and yellow-orange tubercles, white marginal semicircles, and, in particular, the yellow-orange edge to the mantle. In contrast, Fryeria bayi is white to cream in colour with fine, pale brown markings. Fryeria guamensis differs in having paler yellow coloration, numerous small tubercles around the mantle margin, and in lacking white semicircles or yellow-orange coloration on the mantle edge.

Concerning message #15150:
I'm doing the management plan of Dibba Marine Protected Area in Fujairah Emirate, East coast of UAE (Gulf of Oman). I take a lot of pictures during my dives, and this is a nudibranch I found in March in a sand area near a coral reef.
I think this is a Fryeria rueppelii, but I'm not sure. Can you help me identifying?

You don't give an indication of the size of the animal, but if is quite small, it could well be a juvenile F. rueppelii in which the yelow border is not fully developed.

It is possibly a sponge colony, but I am afraid I can't see enough detail to be sure. Phyllidiids all seem to eat a group of spiculate sponges, and unfortunately even with a photo showing the external structure in great detail they are usually more difficult then non-spicuate sponges to identify from photos alone. That is not to say I don't want photos like this because they give us valuable information which can be used when food sponges are identified from actual sponge specimens.

This is Fryeria rueppelii, a phyllidiid nudibranch which until quite recently was known only from the Red Sea, so it is good to get another record of it from further afield.

Nathalie Yonow, who described this species 20 years ago, was kind enough to identify the attached photos (from a year ago) as Phyllidia multifaria. She also pointed out to me the positioning of the anus, which is quite apparent in these photos, as a good way to distinguish this species from the more abundant and similarly colored Fryeria rueppelii.

I hesitate to disagree with Nathalie but unfortunately I don't think she has correctly identified your animals. In her original description she definitely describes the background colour in P. multifaria to be pink and black, while your animal has a very bluish appearance. The other thing is that unless you actually saw a hole at the end of the 'anal papillae' I am not convinced that the ringed object is an anal papillae. I wouldn't be surprised if it is a yellow tipped tubercle. It is frustrating having only your photos to look at but I would be very surprised if that is an anal papilla.
Unfortunately neither of your photos show the edge of the mantle so I can't see if there is a yellow border which is characteristic of Fryeria rueppelii, but my feeling is that is what this is. If you have photos that show the edge they would be useful. Phyllidia multifaria was considered by Brunckhorst to be a synonym of P. elegans but as your will see on the P. multifaria Fact Sheet its identity is still being debated. However none of the specimens considered to be 'perhaps' P. multifaria have a colour palette or pattern like your animal.

I think this one just decide to pop out and trick us. I am pretty sure it is an uncoloured juvenile of Fryeria rueppelii, which is the Red Sea species you just sent a message about [#15700]. I can'y say I have much proof to back my identification because we know very little about juvenile colour patterns in phyllidiids, but if you compare the shape of the tubercles and arrangement of the black network pattern they match very well. And I don't know of any of the bluish-grey species which have this colour pattern as adults.
I suspect this is further proof that Fryeria rueppelii is alive and well in Western Australia.

I'm very glad you had doubts about this animal's identity. If you hadn't had doubts we would still not know that Fryeria rueppelii, which is supposed to be restricted to the Red Sea, can also be found on the other side of the Indian Ocean. As far as I know there is no other species of phyllidiid with this characteristic colour pattern.
This is an exciting extension of the geographic range of Fryeria rueppelii and may cause us to reconsider some of the species in this groups which have been based on quite retsricted geographic distributions.

Attached is a photo of what I believe to be a Fryeria rueppelii. You mentioned in other posts that it seems to be restricted to the Red Sea, but given your descripton of the species and it's yellow border I think they may be present in the Gulf of Oman also. This shot was taken in Khor Fakkan, UAE last month. I come across this species quite often at depths between 15 and 25 meters.

Until now this species has only been recorded from the Red Sea, so your observation is an additon to our knowledge of the species. Our knowledge on many nudibranch distributions is still very poor so any records you have from along the northern Indian Ocean - Arabian Sea region would be welcome.

Many of the photos you have sent are of the nudibranch family Phyllididae. These are often quite common, or at least very visible during the day, because they retain noxious chemicals from their sponge food in their own tissues, much like the ovulid in your earlier message. This species is Fryeria rueppelii, a species which is only known from the Red Sea.

After sadly ignoring them for some time I am making an effort to identify the phyllidiids I have on slide. I don't find them at all easy to identify and this is one I'm not sure of. Could it be Fryeria rueppelii?
The specimen was photographed on 16 October 1992 at a depth of 5m on a coastal fringe reef at 'Black Mountain', about 550km south of Jeddah [Saudi Arabia, Red Sea]. It was 25mm in length.
Thanks for all your help.

Yes this is Fryeria rueppelii. I am also impressed that you got the spelling correct. Every time I see a species with Rueppel's name in it I have to check the spelling as there have been numerous mispellings in the scientific literature, and I must admit I am never too confident I have it right.

Can you tell why Fryeria rueppelii Bergh, 1869 is spelled with one 'l'? I attach a file with the right spelling, because I think computers all over the world don't work with the German alphabet (my own name is a good example). If it is named in honour of Rueppell it should be spelled with 2 'l's - posthumous he should be glad that the name is not Ruepel - the German meaning of this is boor, rowdy.
Medslugs.Koehler@t-online.deErwin Koehler, 2000 (Mar 1) Spelling of Fryeria rueppelii. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/1998
The apparently incorrect spelling of the name is based on two articles of the International Code of Zoological Nomenclature. Firstly names with marks such as 'ü' have to be transliterated into standard alphabet as you have illustrated above. This Rule existed long before computers but I must admit converting your Köhler to Koehler so that search engines will find your name.
The second point is that the spelling of published names can only be changed in exceptional circumstances. Basically for a mispelling to be corrected there must be evidence within the paper where the name is introduced to show that a mispelling has occurred. For example if an author writes "I name this species Doris morgaretae after my wife Margaret, there would be grounds to change the name to D. margaretae on the grounds of a mispelling or typographical error. However if the author had just said "I name this species after my wife" without mentioning her name, then there would be no grounds for amending the spelling at a later date.
In the case of Fryeria rüppelii there is no indication of a mispelling in the original description. Here is a paraphase of part of a submission to the International Commission to clarify and stabilise the name Fryeria rüppelii as the type species of Fryeria. [Brunckhorst, Rudman & Willan (1989) Case 2682 Bulletin of Zoological Nomenclature 46(3): 161-164], where this question was discussed:
"The name Fryeria rüppelii was proposed by Bergh (1869). The spelling of the specific name has been inconsistent and the following variations have been used: rüppelii, rüppellii, rüppeli, ruppelli, ruppelii, rueppelli. Bergh (1869) spelt the name rüppelii and this name must be corrected to rueppelii according to the International Code of Zoological Nomenclature. The species rüppelii is named after Rüppell, but Bergh consistently misspelt his name 'Rüppel' in his 1869 paper. It is therefor not permitted to amend the name to rueppelli as there is no indication in the paper of a spelling error".
Under the Rules if Bergh had said he was naming the species Fryeria rüppelii in honour of Eduard Rüppell then we could change the spelling. I know it sounds silly but it saves uncertainty and later arguments about spelling of names.
