Brian Sellick Can anyone help with this one.
Sodwana Bay - South Africa, East Coast
35mm
Jane Doherty Chromodoris Elizabeth I think. See a lot in the Red Sea.
Jane Doherty or Elizabthina
Jeff Rosenfeld Looks more like Chromodoris strigata to me.
Jane Doherty Really??? They have broken stripes though surely? I'm no expert though...
Jeff Rosenfeld A good resource is: http://www.nudipixel.net/species/chromodoris_strigata/
Brian Sellick I've been searching on The Seaslug Forum and I agree with Jane, Chromodoris elizabethina. The white band between the black stripe and the orange mantle margin is the key. Very similar to variations of Chromodoris hamiltoni.
Jane Doherty Im still not convinced ;) http://www.nudipixel.net/photo/00032658/.
Brian Sellick Look at the Seaslug forum.
Brian Sellick My apologies Jeff, I have done some more research and I also think it is a Chromodoris strigata.
Dewald Swanepoel I'm going to have to disagree with all of you and call this a Chromodoris africana. All these C. elizabethina and C. strigata slugs are western Indian ocean and pacific ocean critters. On the other hand, C. africana is arguably the most common slug in Southern African waters.
Jane Doherty haha! I've looked at various pictures of all 3 now and they all look the same to me ;-)
Mohamad Izwas Can anyone help me to determine this Chromodoris? There are few similar but not really same with this one.

No color adjustment, just crop little bit and write watermark only.
Blogie Robillo I think this might be Chromodoris strigata.
Blogie Robillo Btw Mohamad, in this forum, it is not necessary to include camera settings. What's more important here when asking for ID are location, depth and size of the creature. :)
Mohamad Izwas Ok, Found in Mabul Island Sabah. Size like normal adult chromodoris magnifica. I'm not sure metric measurement.
Bob Whorton It's not 'strigata' that is much more like the common chromodorids and not as chunky in the body, with a broader mantel.
Bob Whorton Now having looked at it big, it might be strigata - doh!
Erwin Koehler here is a headache species from the Red Sea, it looks like
Chromodoris colemani Rudman, 1982 or like
Hypselodoris regina Marcus & Marcus, 1970
Help!
Gary Cobb According to Yanow I think this can only be Chromodoris strigata
Gary Cobb This species has been known to have brownish streaks on the mantle. Of course DNA will separate them quite nicely!
Erwin Koehler thanks, I will go with C. strigata for now...
Elodie Camprasse Hello Nudibranch Lovers! I am writing an article on nudibranchs in Vietnam and I'd like to be sure of the identification of species on the photos I am going to submit... Is this Chromodoris michaeli or quadricolor?
Jason Jue Is this a Chromodoris strigata? Pattern seems slightly different from what I'm seeing online via Google.
Malapascua, Philippines. 15 meters deep.
Gary Cobb This is Chromodoris cf. colemani. C. strigata has no yellow on the mantle between the black lines.
Bob Whorton Can anyone ID the little guy in this old shot from Wori Bay N. Sulawesi please?
Mike Bartick with the plume in its a tough call,,,Chromodoris magnifica
Deb AstonHypselodoris apolegma
Deb Aston Sorry H apolegma is the big one.
Deb AstonChromodoris strigata for the little one.
Gary Cobb Nice photo!
Gary Cobb The large one is Risbecia apolegma Yanow, 2001 and Chromodoris strigata Rudman, 1982
Jim Anderson It's now Hypselodoris apolegma (Yonow, 2001)
Gary Cobb Jim where did you get that information?
Gary Cobb This was never proven in a scientific paper and Yanow still thinks it is Resbecia. The Sea Slug Forum was only speculating and a paper has never been written that officially changes the Genus.
Gary Cobb Bill Rudman:
"This 'species' has recently been described as Risbecia apolegma. On the Forum it has been considered closely related to Hypselodoris bullocki. Whether it is a colour form of that species or a distinct species is not clear to me. Have a look at the messages on the H. bullocki and H. apolegma pages to see some of the colour variation and discussion. Also look at Phil Slosberg's photo showing typical H. bullocki and H. apolegma mating."
"Hypselodoris apolegma differs from H. bullocki mainly in colour. The background colour is a rich pinkish purple with a white border to the mantle. At the edge of the mantle the border is solid white but inside this is a region of varying width in which the white forms a reticulate pattern gradually merging in to the pinkish purple. The rhinophore stalks and the base of the gills is an intense purple, the rhinophore clubs and the gills are orange yellow. I can find no anatomical grounds to place this 'species' in the genus Risbecia."
Ed. This is Bills thoughts on the species, so you see there was never a paper written proving that the genus is Hypselodoris BUT there a paper by Yanow proving that it is Resbecia. Unlees you know of one we stick with the latest papers finding.
Bob Whorton It's nothing like a Risbecia in reality, and everything about it screams Hypselodoris, Was Yanow sober? H. bullocki is distinctly different from apolegma, and how it was ever associated beats me. Bullocki has a distinctive semi translucent skin over a layer of colouration giving it an opaue effect, with a thin white border around a sharper mantle edge. The behaviour of the two is quite different too.
Jim Anderson I got this from Dave Behrens - seeGosliner, Behrens, and Valdes, Indo-Pacific Nudibranchs and Sea Slugs for reference.
