Unidentified sea slug from South Africa

March 3, 2010
From: Neil Wiltshire

Dear Mr Rudman,

Further to my previous message, here is the second specimen of the unidentified sea slugs (pleurobranch's) I photographed recently.

As mentioned, I am not sure if this is a second species or a variant of the first species. [see message #23283]

Locality: Unnamed reef near Aliwal Shoal, off Umkomaas, south of Durban, 25 metres, KwaZulu-Natal south coast, South Africa, Indian Ocean, 24 January 2010, Flat sandy bottom, next to reef. Length: 150 mm. Photographer: Neil Wiltshire.

Thanks very much!

Best regards,
Neil

Dear Neil,

It certainly looks similar to the pleurobranch in your last message, but I have some doubts. One of the difficulties with identifying from photos is that I can't just turn the animal over and see if it is a pleurobranch or not. It has definite similarities to some dorid nudibranchs such as species of Hoplodoris, but in that group the bases of the tubercles are usually separated. If it is a pleurobranch then there is the possibility it is a large specimen of P. albiguttatus. One distinguishing feature of that species are the scattered tubercles it has, each with a triangular white mark on them. I have ringed two such white marks in the close-up alongside.

Unless you have another photo which shows the head tentacles I'm afraid I will have to leave this as an 'unknown'

Best wishes,
Bill Rudman

Unidentified dorid from Mozambique

May 30, 2008
From: Valda Fraser

Dear Bill
An ugly, brown fellow on the prowl at night. The gills were not visible and I waited and waited. Eventually gave up, but decided to turn it over and photograph the underside. Maybe this will help with identification. Hope you can come up with a name.

Dear Valda,

I thought at first this was very similar to Discodoris sp. 2, but then I noticed the dorsum is covered in large tubercles which appear to have a retractile papilla at the tip. Some of the tubercules appear to have a regular axial symmetry with rings of secondary rounded tubercules and ridges but I would need another photo to be sure. Hopefully one of the Californian group who have been looking at these 'flat' dorids will recognise it. The gills look as though it could be a species of Actinocyclus, but the mouth and head region looks quite different [see #14528].

Best wishes,
Bill Rudman

Striped dorid from South Africa eating what?

Dear Valda,
I am still no closer to a name for this animal. It certainly has some similarities to Paradoris sp 1 and Paradoris sp 2 but that doesn't get us far as I don't really know if they are really species of Paradoris. Perhaps Terry Gosliner's school of dorid experts can give us some comments.

Concerning the pink stuff. My first thought was an octocoral with retracted polyps and on close examination I found what looks like a semi-retracted polyp with 8 tentacles which would support my octocoral idea. If the dorid is eating the pink stuff, and if it is an octocoral, that would be interesting, as dorids don't normally feed on cnidarians

Best wishes,
Bill Rudman

Re: Possible Eubranchus from False Bay

June 11, 2007
From: Guido Zsilavecz


Hi Bill!
On a dive recently I also saw what I think may be a species of Eubranchus which is not in Gosliner, but looks similar to other Eubranchidae shown on this forum.

There were two varieties, one with red digestive tract extensions into the cerata, one with white. I found them close together, and with a number of egg ribbons, as can be seen in the group image. I have a close-up of the egg cases too, which I can send if needed.

Locality: Cape Town, 15 meters, South Africa, Atlantic Ocean, 9-April-2007, Hydroid colony on rock reef wall. Length: 15 mm. Photographer: Guido Zsilavecz.

Could this be a new species or is it familiar to you?
Thanks,
Guido

Dear Guido,
This is an aeolid but I don't think it is a eubranchid. From the way the cerata are arranged in many transverse rows, and the apparent lack of tentacle-like extensions to the anterior corners off the foot, my considered 'guess' is that it is a species of Cuthona.  

I can't find - or recall - it, so perhaps it is an unnamed species. Perhaps Terry Gosliner can give us a comment.

Possible Eubranchus from False Bay

May 25, 2007
From: Georgina Jones


Dear Bill,
I found this small nudibranch the other day -- the photographs aren't fantastic, but I think it is a species of Eubranchus which doesn't appear in Gosliner's reference book. What do you think?
I have included a picture of the egg ribbon which were next to the nudis -- they weren't actually laying them, but I thought the proximity suggestive.

Dear Andrew,
In future can you split messages with 3 different species into 3 separate messages. It saves me a lot of time and allows me to arrange species more logically on the Forum.

I must say the egg ribbon on the bottom left of your photo is interesting, although we can't be sure it belongs to your animal. The eggs in it are quite big, suggesting the larvae may hatch out as crawling young slugs, rather than as swimming planktonic larvae, which is the fate of most nudibranch young.. Having said that, I'm afraid I haven't an answer for any of your 3 species! In the past  I have put messages such as yours to one side until I can check them out or ask other experts for help. But in this case I think I'll try posting them and see if I anyone recognises them. We are building quite a pile of unidentified Sth African species, which is I guess not surprising, considering the the mix of animals from the tropical Indian Ocean, and the cooler Atlantic, as well as an endemic cool temperate fauna - and so little work being done on the fauna - despite the sterling efforts of Terry Gosliner.

Hopefully in can give us some clues

There have many a number of black-spotted dorids reported from South Africa [see #14763] but none seem to fit this animal.

Unknown dorid - Gargamella? - from Sth Africa

Hi Bill,
Here is a nudi from our wreck in Algoa Bay. This one makes 5 different nudis from a very small site indeed! This one was spotted on the sand next to the wreck in about 20 metres on its own. It was about 40 mm long.

Since buying my new camera an Olympus 7070 I have been able to enlarge my shots quite a bit more and in doing so I am amazed to see that some nudis are bumpy! That is to say the epidermis is not smooth but almost warty. Very interesting.

Dear Charles,
Thanks for this. We already have a message about this from Valda Fraser [#4866]. There are a number of whitish dorids with blackish or dark brown spots from Sth Africa, including a new species of Gargamella. However, none of them seem to have the distinctive opaque white submarginal line around the mantle border which is so distinctive in both your photos and Valda Fraser's. There is also Aphelodoris sp. 4 but it is an opaque white and the rhinophores are black. May be Terry Gosliner will recognise it for us

Armina from South Africa

October 1, 2002
From: Valda Fraser


Dear Bill,
A friend at the Oceanographic Research Institute in Durban knows of my love of nudibranchs and called to tell me about some horrid beasts that had eaten all five sea pens (Virgularia sp.) that were being carefully nurtured. The sea pens died one after the other, and only when the tank was cleaned out, were the culprits found in the sand – alive and probably hungry! No one ever noticed the arminids feeding on the sea pens, so it seems that these animals are able to live permanently in the sand. Can you help with identification?
I am sending two images to illustrate colour variation. I especially chose the one photo as the animal has a “piece” missing.

Dear Valda,
This is definitely a species of Armina, and eating sea pens is what they do. Species tend to be nocturnal so it is possible they did their damage after the people at the Oceanographic Institute had gone home for the night. I'm afraid the few species of Armina reported from South Africa were described from preserved animals so a name is not possible at present.

Dear Valda,
I suspect these may be juveniles of two different species. The fact they are small and white and appeared suddenly at the same time suggests they are the result of late winter / early spring breeding. We get a similar influx of juveniles in August here is southeastern Australia.

Juvenile tritoniids have proved tricky to identify and in Europe the juveniles of the large common Tritonia hombergi were for many years considered to be a distinct species, the animal not getting its adult colouration until quite late in its development.

Dear Valda,
It could be Cratena capensis Barnard, 1927 but it is more likely to be Gosliner's Cratena sp. 1 which has rhinophores and oral tentacles of about equal length.

I can't see the 'black gland' below the tip of the cerata which Terry says is characteristic but then I can't see it in the photo in his book either. There is a darker region at the top of the digestive gland as in your photo. Another point si that Barnard says the rhinophores and oral tenatcles are white in Cratena capensis while in your animal (& Gosliner's) the rhinophores are orange.

Best wishes,
