Arantxa Di Mare Hi Sven, I think it could be Hypselodoris apolegma...:)

Sven Kahlbrock possible

Roy Arthur David Lontoh Possibly apologema....I think bulloki has solid thin white line

Penn Dls Mating. What are these called?

Penn Dls from Anilao, Philippines

Sylvie Omnès Hypselodoris Bullockii 1881

Gary Cobb These are Risbecia apolegma Yonow, 2001 and I am not aware of any papers saying it was changed to Hypselodoris! The Forum assumed it was that genus but it was never proved.

Sylvie Omnès apologize Penn and Gary for the mistake ... I didn't saw the details of the mantel . Those are given like Hypselodoris Apolegma Yonow 2001 in "Nudibranch of the World"Deblius/Kuitter...

Blogie Robillo For reference (and for my peace of mind), is this H. bullockii? http://www.projectnoah.org/spottings/7876388

Sylvie Omnès Joker ... ;-)

Christopher Thorn Chromodoris what sp? Sand Island, Taiwan. 13m. 40mm.

Christian Skauge Hypselodoris bullocki, isn't it?

Christopher Thorn Not a Chromadorididae at all :-) Thanks.

Patrik Good spelling would be bullockii :-)

Christian Skauge Not according to WoRMS ;-) http://www.marinespecies.org/aphia.php?p=taxdetails&id=560043

Patrik Good Sorry, Christian Skauge. Glad I posted though. The master has to do some explaining then if he is not too busy :-)

Christian Skauge haha there's always controversy regarding i or ii at the end of species' names - think nothing of it ;-)

Andy Gray Maybe it's Hypselodoris apolegma or a Giant hypselodoris. Chromodorididae sp. I think there are colour differences in the H. bullockii anyhow. H.Bullockii are very similar.

Christian Skauge I'm no expert on these species, I just suggested the name so you might well be right Andy :-)

Roy Arthur David Lontoh In my humble opinion, this is Hypselodoris apolegma, Hypselodoris bullockii has a solid white line along the mantle.

Bernard Picton Hypselodoris apolegma. I think H. bullocki may be several things so keep photographing purple things with white edges...

Gary Cobb This is Risbecia apolegma Yonow, 2001

Gary Cobb By the way WoRMS is very unreliable and out of date!!

Blogie Robillo Gary Cobb - What's the best way to tell R. apolegma and H. bullockii apart?

Bernard Picton There is a lot of information on these pink-purple, white edged, species on the Sea Slug Forum.

Bernard Picton http://www.seaslugforum.net/find/hypsapol

Blogie Robillo This is getting more & more confusing...

Bernard Picton The interesting ones are the ones where the experts can't agree yet.... Note Bill R says "I can find no anatomical grounds to place this 'species' in the genus Risbecia" and note the ' ' around species. Because these Chromodorids mimic each other for protection from predators there are often "mimicry rings" which may involve several genera, and flatworms, even ovulid snails which mimic Phyllidia.

Blogie Robillo I guess that's what keeps us fascinated with these critters!

Ron Silver Appears to be Hypselodoris apolegma.

Goh Diving Thanks Ron...you are absolutely correct.

Ron Silver No problem. I'm sure you were just checking to see if we were paying attention! Thanx for posting your photos.

Goh Diving I have to disagree with you this time :) You are welcome.

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 Aston Hypselodoris apolegma

Deb Aston Sorry H apolegma is the big one.

Deb Aston Chromodoris 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.

João Pedro Silva Hypselodoris apolegma. A faixa branca ao redor do manto tem uma transição típica com pontos, diferente em Hypselodoris bullockii em que essa faixa é claramente delimitada. http://www.nudipixel.net/species/risbecia_apolegma/

Carol Roldan Martin Jo tb crec q es la hyposelodoris apolegma...testas pegant unes capbussades guapis guapis...
