Hypselodoris sp. from New Caledonia

November 3, 2006
From: Jean-François Hervé


Dear Bill,

Attached are photos of another Hypselodoris I found last month.

Locality: Noumea, 15 m, New caledonia, Pacific Ocean, August 06. Length: 20 mm. Photographer: Jean-François Hervé.

It seems to look like Hypselodoris peasei with the white lines but it's endemic to Hawaï and there are some differences.
Thank you.
Best Regards.
Jean-François

Dear Jean-François,
This is a species I am at present calling Hypselodoris cf carnea, not because I think its closely related to Hypselodoris carnea but simply because it looks quite like it.

Best wishes,
Bill Rudman

Dear Bill
I can't identify this nudibranch. I found it at Surin Island and photo by Dr. Thon Thamrongnawasawat. I don't record date and depth.
Thank you

Dear Narongpon,
Sorry it has taken me a while to reply to this message. This is a species I am temporarily calling Hypselodoris cf. carnea.

Hypselodoris cf. carnea feeding

January 19, 2001
From: Nerida Wilson

Hi Bill,
These pictures of a Hypselodoris sp. feeding were taken in the Dampier Archipelago in August 2000. Jane Fromont is in the process of identifying the sponge, so I will let you know what is it in the near future
Cheers

Thanks Nerida,
The sponge looks like a Dysidea, but from experience, I know it's better to wait for the experts to decide.
Best wishes,

Hypselodoris cf. carnea from Taiwan

January 19, 2001
From: Bernard E. Picton

Hi Bill,

Here is a picture of an animal which I collected in Taiwan in April 1983,
(North Coast - my no. BEPTA/14). I've never been able to name it, but I think it is identical to Clay Bryce's 'Hypselodoris carnea' from Western Australia (Forum: Feb 13th 1999).

Thanks Bernard,
With the information now available it is clearly not the South African H. carnea. Although it lacks the white lines, I would agree they are probably the same.

Hypselodoris carnea? from Western Australia

February 13, 1999
From: Clay Bryce

Bill,

A little extra info on Hypselodoris carnea. The attached image is from the Dampier Archipelago (The Kimberley, NW Australia). Station 33; the site is in Flying Foam Passage which has a fine silty substrate with a sparse sponge, soft coral and Turbinaria (hard coral) garden. The animal was found on a rock between possible food sources - as usual! Size: 3cm.: Depth 11m.: Collection date: Oct. 1998: Reg. No. 12054.

I have it down as H. cf. carnea due to the excess of brown lines (or is it brown dots that have joined?). But it does make a nice merge with the true H. carnea from S. Africa and those from E Aust. Some of the images in the Forum seem to look a bit like H. capensis as figured in Terry Gosliner's Nudibranchs of S.Africa.

Thanks Clay,
It will be interesting to see if anyone can help close the gap across the Indian Ocean.

Hypselodoris carnea? from New South Wales

February 12, 1999
From: Carol Buchanan


Hi Bill
It's a good feeling to be able get involved in nudibranchs again, even though it is from above the water at this stage! I've been wandering about in the Sea Slug forum and
found a message from the Atkinsons re Hypselodoris carnea & your reply. I have found and photographed these little beasts quite a few times in the Solitary Islands, (northern new South Wales, Australia) although their colour is a bit variable. Anyway, here are photos of different specimens.
    
I'm more than happy to help out in the Forum, as I said , its good to be involved again. I'm currently off work until 1st July so have at least a bit of spare time on my hands.

Regards,
Carol Buchanan

Dear Carol,
I'm glad to hear from you and any help with the Forum will be greatly appreciated. As you will have seen, quite a few people have questions about keeping nudibranchs in aquaria. I'm sure your expertise in that area will be of great value, as will any photos of interesting animals and even of boring ones doing interesting things.

Thanks for the photos of this Hypselodoris carnea lookalike. If it is indeed H. carnea the species has a strange disjunct distribution, being known only from the western Indian Ocean and eastern Australia. I would very much like some specimens if you find any.
Best wishes,
Bill Rudman.

Hypselodoris carnea at Fly Point

March 19, 1998
From: David & Leanne Atkinson

Bill,

I found Hypselodoris carnea at the weekend at Fly Point, Port Stephens in 8M. My book (Nudibranchs and Sea Snails by Helmut Debelius) says that they are East Indian Ocean dwellers. The first I have seen. Are many found here?

It certainly looks quite like photos I have seen of Hypselodoris carnea. The main colour difference appears to be that the orange-brown lines in your photo are distinct spots in Indian Ocean specimens. Also the border around the anterior end of the mantle in Indian Ocean specimens is an unbroken bluish line, while in your Port Stephens animal there is a row of purplish spots around the mantle edge. These differences may not necessarily be of significance but I would need to have a look at the anatomy of a specimen, including its reproductive system and the shape of its radular teeth, before I could confirm its identity. From the photo I can't even be sure it is a species of Hypselodoris. It could equally be a Chromodoris. Whatever it is it is very interesting and something I have not seen in eastern Australia before...Bill Rudman
