David Ennew chromodoris elisabethina 25 mm flynn reef Cairns 8m
Blogie Robillo What are the characteristics of C. elisabethina that can help us differentiate it from C. annae, C. colemani?
David Ennew Gary can you help with this comment , cheers Dave
Ashley Missen It's the black speckles on the C. anne - have a look at the differences C. annae http://www.dragonmouse.com.au/diving/nudibase.php?action=nudidetail&id=363 -- C. elisabethina http://www.dragonmouse.com.au/diving/nudibase.php?action=nudidetail&id=30 -- C. colemani Chromodoris colemani
Ashley Missen C. colemani -- http://www.dragonmouse.com.au/diving/nudibase.php?action=nudidetail&id=214
Blogie Robillo Thanks Ashley Missen!
Gary Cobb OK the main difference between Chromodoris elisabethina and C. annae is the C. annae has "pits" in the blue part of the mantle. C. colemani usually has black lines on the dorsum surrounded in white. This species hardly ever has blue more tan colouration. C. annae has very few black lines on the dorsum in the the blue if any, while C. elisabethina can have several.
David Ennew This Cobb bloke is a genius
Gary Cobb Geeeeez! Thanks David!
Blogie Robillo Gary Cobb - What about C. strigata? What should I look out for to be able to ID it properly? :)
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...
Christopher Thorn Hi, are these all colour variations of C. magnifica? All individuals photographed on 27/5/12 at Water outlet, Kending, Taiwan. 10 m. 30 - 50 mm.
Blogie Robillo The pair on the lower right are Chromodoris annae.
Christopher Thorn Thanks Blogie, I checked that out on theseaslugforum, seems you are right; they exhibit the pitted blue coloration if c.Annae. Do you think the others are C.magnifica?
Blogie Robillo The upper-right photo shows C. magnifica, but the other two...I'm not sure.
Christopher Thorn Ok, thanks for your input as always:-)
Christopher Thorn upper right also resembles C.elisabethina doesn't it?
Blogie Robillo If I'm not mistaken, C. elisabethina does not have a white mantle outline...
Franca Wermuth-Vezzoli Could the one on the upper left be Chromodoris colemani?
Blogie Robillo ID for this Chromodorid pls?
3cm long, in less than 5m of water.
Gena Kokonas Just wondering Blogie, so you dive every day, all day long? ..... I am jealous.
Nice shot.
Shauming Lo Beautiful Nudi Blogie Robillo!
Andre Snoopy Montenegro wow nice one blogie!
Blogie Robillo Thanks guys! No, Gena Kokonas, not everyday -- but I would if I could! :D
Kati Burg Looks like chromodoris colemani: http://www.nudipixel.net/species/chromodoris_colemani/
Blogie Robillo I do tend to agree that this is C. colemani... *sigh* I thought I'd found a new addition to my nudi species list -- I already have C. colemani, but no C. elisabethina yet. Oh well, still quite happy with this one.
Blogie Robillo Maybe for now I'll put it down as Chromodoris cf. colemani, just until I get confirmation from the experts at Nudibase. :)
Arne Kuilman But a very beautiful nudibranch!
Blogie Robillo It certainly is, Arne! And I have a video of it too ;)
Blogie Robillo OK, I got word from Gary of Nudibase that this one is Chromodoris cf. strigata.
Kati Burg Really? C. cf. strigata.? C. strigata looks so different. Check out this photo and the comment by Dr. Richard Willan : http://www.nudipixel.net/photo/00002451/
Blogie Robillo Kathrin - Mine doesn't have fused rhinophores...
Kati Burg This group of nudis is so complicated - I guess there will be a few more species found in this species complex within the next years.
Blogie Robillo They sure are complicated! But I guess that's what keeps us on our toes. ;) Watch out for the video of this critter -- uploading it to youtube now.
Blogie Robillo More photos & video of this nudibranch here: http://www.projectnoah.org/spottings/13899355
Blogie Robillo Is this Chromodoris elisabethina?
Spotted it in abt 7m of water, size 3cm.
Blogie Robillo Hmmm... on 2nd thought, maybe not C. elisabethina. Maybe C. colemani?
Erwin Koehler the first half of your first thought is correct: Chromodoris,
the second thought very close, Chromodoris cf. colemani,
the real Chromodoris colemani has 5 black lines, it might be a variant,
or a distinct species...
Blogie Robillo Erwin - Might you supply the other half? ;)
Erwin Koehler Done!
sorry, I have always the same problem with FACEBOOK, very difficult for an old man (me: 61) who had been working almost half of his life (started 1977, retired 2005) with/on computers (mainframe IBM and Siemens products) to accept-learn that the "enter button" is not the next line button, as it is in ALL editors which I was and am used to....
now, only at facebook suddenly "shift and enter" if you like 'next line', I know it, but forget it again and again, shit when you become OLD!
Blogie Robillo Hmmm... so I'll put this down as Chromodoris sp. for now. Unless Gary Cobb chimes in with something more definite...
Blogie Robillo LOL Erwin!
Gary Cobb This is Chromodoris cf. strigata http://www.seaslugforum.net/chrocfstri.htm
Gary Cobb Glad I could help:)
Blogie Robillo Yehey! A new one indeed for my collection! Thanks Gary :)
Blogie Robillo Pls help ID these two dorids? For the life of me, I still find it difficult to differentiate among Chromodoris magnifica, C. annae, C. elisabethina...
Both nudis were spotted at a depth of 5m, and each measured roughly 3cm long.
Blogie Robillo No takers?
Deb Aston I would guess either Chromodoris michaeli or Chromodoris colemani
Roy Arthur David Lontoh I think the one on the left is Chromodoris mihaeli and the one on the right is Chromodoris hamiltoni?
Blogie Robillo Thanks for your input, guys, but I think C. michaeli is out of the question. Accdg to existing descriptions, C. michaeli's dorsum should have a "fine speckling of white' on a translucent bluish or brownish ground color. Neither of the two above has such.
Blogie Robillo I'm still confused what the one on the left could be, but the one on the right just might be Chromodoris hamiltoni....... Anyone?
Blogie Robillo OK, based on the message in this link, the one on the right could very well be C. hamiltoni: http://www.seaslugforum.net/message/22337
Blogie Robillo Hey Gary Cobb, any thoughts? :)
Gary Cobb Where we're these found? Chromodoris hamiltoni is a west Indo pacific species and other species may aquire pigmentation.
Blogie Robillo Gary Cobb - Both were found off the eastern coast of Samal Island, south of the Philippines.
Franca Wermuth-Vezzoli I had the same problem: http://www.seaslugforum.net/find/23081 and http://www.seaslugforum.net/find/20173. I file my nudi as a Chromodoris magnifica.
Gary Cobb Yes these Nudibranchs can be quite a problem. I would say the two photos above are Chromodoris magnifica (Quoy & Gaimard, 1832). This species can have brown smudges. C. annae has "pits" in the blue region of the mantle. C. hamiltoni is from the Western Indian Ocean i.e.. Africa.
Roxanne Fea I find identifying these types of nudibranches can be maddening...
Blogie Robillo yeah maddening, but like a drug :D
Gary Cobb Fairly simple if you know what morphology separates the species. Also don't forget that DNA will give a positive result, we can only hazard a guess based on "time in the saddle"!
Blogie Robillo I'll settle for "time in the saddle" ;)
