Hypselodoris bullockii

(Collingwood, 1881)

Kristin Anderson Group hug | Lembeh Hypselodoris bullockii

Bernard Picton I wonder if they give off a chemical when they are mating which attracts others?

Blogie Robillo Love this shot!! (^^^)

Deb Aston Size doesn't matter with these guys either, often see a larger specimen mating with a much smaller one.

Gary Cobb Another beautiful critter is Hypselodoris bullockii (Collingwood, 1881) found at Flinders Reef, Moreton Island 3rd of March 2012, about 40 mm long posing!

Wil Yu Can this species be different colors? I have one like this but it is orange.

Ex Liao ID please, took this in Punta Engano, Mactan, thanks...

Jun V Lao hypselodoris bullockii nudibranch :)

Ex Liao thanks jun

Carl-Johan Nilsson Color on the bullockii varies a lot. Really like this pale one.

Bob Whorton This is now redesignated H. apolegma.

Ex Liao About 3cm long

Arnico Lumangyao Cartalla "Balancing Act" Lembeh, Indonesia

Jon Chamberlain Looks like Hypselodoris bullockii. I've seen this behaviour in other large species where they find a stick to climb on. Nont sure what possible benefit it could give them, perhaps they just find it amusing?

Arnico Lumangyao Cartalla it was suspended like that for I don't know how long i thought its about to lay eggs or something

Christopher Thorn C species? Coron, 25 m, 25 mm.

Roy Arthur David Lontoh Looks like Hypselodoris bullockii

Erwin Koehler At least very close related to H. bullocki(i). I don't know how many 'i'

Christopher Thorn Mabul, 10 m, 40 mm. Can anyone help id this nudi please? I've looked through nudipixel and nudibase and can't seem to find it.

Gary Cobb This is a blue colourform or Hypselodoris bullockii (Collingwood, 1881) http://www.nudibranch.com.au/pages/4656d.htm

Blogie Robillo Spectacular!

Christopher Thorn Thanks for clearing up the mystery for me Gary. (Am i missing something? is the link relevant?)

Jim Anderson Is this not what Rudman has called Hypselodoris cf bullockii

Gary Cobb Sorry wrong link!!:( LOL for all intent and purposes it still fits the bill for one of the most color varied species. If we call this one 'cf' where do we draw the line?

Jim Anderson We let Bill Rudman do that!

Gary Cobb Bill Rudman is no longer in the world of Opisthobranchs

Jim Anderson So where was this variation upgraded to the full species?

Barbara Caldwell Who me ? Nudi at Lembeh

Ron Silver Hypselodoris bullockii

Barbara Caldwell Thanks - I was looking for the name and got the "bullockii" but it was a tag on someone else's photo and I didn't dare use it ... just in case it was an "in" joke :)

Ron Silver No problem. Pretty informal overall but I do try to get the correct identifications. Thanx for sharing your photo(s).

Chris Cunnold About 8mm long, found in 8 metres in Tulamben, Bali. Any identification ideas?

Franca Wermuth-Vezzoli Hypselodoris bullockii

Daniel Messom Could be "Purple Thorunna"Nev's Encyclo. page 196.

Franca Wermuth-Vezzoli Very interesting, Daniel Messom, I didn't realize the difference.. Now I looked through my nudi pictures and found one with low gills- I will post it to be sure..

Roy Arthur David Lontoh My opinion is similar to Daniel Messom :)

Erwin Koehler Thorunna halourga Johnson & Gosliner, 2001

Chris Cunnold Thanks everyone.

IkeBe Ph 5mm at a depht of 60 ft Anilao, Batangas

Blogie Robillo What a beauty!!

Mark Farrer Thats a stunning little Nudi

PT Hirschfield real purty :-)

IkeBe Ph Thank you Blogie Robillo, Mark Farrer, PT Hirschfield!

Sylvie Omnès is it Hypselodoris bullockii, or another ?

Johny Leffelaer Its not H. bullockii.

Johny Leffelaer I'm not shore,but i think its Durvilledoris similaris.;-)

Jeff Rosenfeld Not Durvilledoris similaris as that species has a line down the midline that the specimen in your photo lacks. Most likely Thorunna halourga - http://www.seaslugforum.net/showall/thorhalo

IkeBe Ph Thank you for the ID Jeff Rosenfeld!

Bunnee Gamboa-Santos I have a funny feeling its not a Thorunna halourga because of its red orange rhinopores and gills. Its the first of its kind that I've seen. I'm not an expert, just my two cents worth.

Sylvie Omnès Bunnee Gamboa-Santos: I think Jeff ID is the right one;look at his link above : at the end of it there's "Thorunna speciosus", very similar ...

Bunnee Gamboa-Santos Yup. Thanks.

Erwin Koehler Thorunna halourga Johnson & Gosliner, 2001, there are specimens with a thinner or a broad white margin are at http://www.philippine-sea-slugs.com/Nudibranchia/Euctenidiacea/Thorunna_halourga.htm

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!

Franca Wermuth-Vezzoli So far I thought this is Hypselodoris bullockii, but now I wonder if it is maybe Thorunna daniellae? Can anybody help?

Erwin Koehler I guess you meant T. halourga Johnson & Gosliner, 2001

Franca Wermuth-Vezzoli Yes, sorry, I meant T. halourga - is my picture T. halourga?

Timothy Nguyen Found this one just beyond Flinders Reef (Gotham City), Moreton Island @ 32m, ~35mm. Hypselodoris bullockii? https://www.facebook.com/photo.php?fbid=10150596092671334&set=a.10150596089821334.377975.562001333&type=3&theater

Roy Arthur David Lontoh Looks like Hypselodoris bullockii

Bob Whorton H. apolegma - 6cm 8m Lighthouse point, Malapascua Philippines

Gary Cobb I think this is Hypselodoris bullockii. "At the edge of the mantle of Risbecia apolegma 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." This photo is a white band. Only an inside view at the anatomy can tell for sure.

Bob Whorton I agree with you on the colour description, but this too differs enormously from the smooth, opaque skinned bullocki. Are we not in fact looking at three completely different species wrongly grouped together? Anotomically, skin make up is a hugely important subject maybe?

Gary Cobb We can only look at a Nudibranch

Gary Cobb It's outside appearance and colour that say "this is what it is" when at the end of the day the internal anatomy will tell. According Yanow she did just that and the anatomy was closer to Risbecia than Hypselodoris. In the case of this colour form we can only guess. The opaque skin would have little in the decision of the species. Life!
