Chromodoris elisabethina is one of a group of chromodorids with a blue or bluish-white background colour and black or dark blue longitudinal lines. Often they have orange or yellow gills and rhinophores and a similarly coloured mantle border. The upper photo could be considered the "typical" colour pattern, but the orange border can be somewhat faint, (and apparently submarginal), and the median black line can be replaced by an irregular group of shorter lines. Chromodoris annae is one of the most similarly coloured species. It usually does not have a median black line and the blue areas of the mantle are not the uniform blue of C. elisabethina but have scattered darker specks, almost pits, throughout the blue areas.
See Scott Johnson's message describing its flattened egg ribbon.

Dear Bill,
Here are some darker coloured Chromodoris elisabethina from Vanuata neither seems to be in the process of feeding. The first paler one is from Olly's Lolly on Mele Reef at Hideaway Island Vanuatu and the darker coloured one in the other photos is from White Rock, Moso Island Vanuatu. Hope they are of interest.

Dear Bill,
Following on from the discussion of Chromodoris elisabethina colouration and food here are some photos from North Solitary Island of one with strong colours near a red sponge. As it moved on the surge pushed its rhinophores so you can clearly see the anus amongst the gills. There was also a Chromodoris magnifica about a metre away. Hope this is of interest you didn't have one from the Solitary Islands and this is the second time we have seen one in this area.

Dear David and Leanne,
Thanks for the photos. Red backgrounds can be deceptive as they are often coralline algae, but this is one of those mixed bottoms with sponge colonies as well. Very tantalising. The only sign of feeding I can see are the whitish tangled grooves on the pink coralline algae which I suspect are the feeding tracks of some herbivorous snail.
If you have a photo of your C. magnifica from Solitary Islands it would be an interesting addition because I can't recall a record from that far south.

Chromodoris from Yap

Dear Bill,
Here two pictures of the same species of Chromodoris, I guess.
They look like C. strigata, but I am not sure because of the unbroken external black line. In the 2nd picture, we can see a part of the sponge, probably eaten by the slug.

Dear Sylvain,
Thanks for these photos. They help to build up a picture of what this species feeds on. The slug is Chromodoris elisabethina and it is interesting to see that one of your animals has a much paler orange colour than the other. I have often wondered why this difference occurrs in a number of these similarly coloured species, and your photos may give us a clue ... but I must emphasise the 'may give us a clue'. C. elisabethina is one of a group of black-lined species which feed on both orange-red sponges of the genus Negombata and blackish or brownish species of the family Thorectidae. I can't be sure if the animal in the upper photo has been eating the orange-red sponge, because there are other sponges present in your photo as well, but I can definitely agree the animal in the other photo has been feeding on the pale brownish sponge which I am pretty sure is a species of thorectid. It is certainly suggestive that the nudibranch with the pale watery orange colour in the mantle is eating a sponge without any red-orange colouration. We don't have enough photos of this animal on their food to see if there is any correlation between animals with bright orange colouration and orange-red sponges but it would be worth looking out for.
In an earlier message [#20951] there is an animal on a similar sponge which I suggested may be a dysideid. On reflection, I am pretty sure it is also a thorectid.

It does have the three characteristic black lines but it has a couple of extra thin ones. If you look at other photos on the Fact Sheet and attached messages you will see that there can be traces of these extra lines as spots and broken lines. The orange-yellow and blue colour can also be somewhat variable.
By the way I have changed your spelling of the name from eli[z]abethina to the correct eli[s]abethina. In these days of digital searching a mispelling like this can mean you miss a lot.

Dear Gary,
This is an interesting feeding record. So far we have only records of this species feeding in thorectid sponges but I suspect this is a species of Dysidea. I will of course have to get its identity checked, but if you have any other photos of it apparently feeding on this, or any other sponge, they would - as I am sure you realise - be very welcome.

Bullen, A., 2006 (Apr 8) Re: Chromodoris elisabethina feeding. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/16266Dear Alex,
Have a look at the Lifespan Fact Sheet and the messages attached on that page for some background information. As to how long a chromodorid would live, I'm afraid we have little concrete information although from population fluctuations during the year it seems that they, like many sea slugs, live for about a year.
If you were wondering about keeping them in aquaria my advice would be not to unless you know precisely what sponge your particular species feeds on and have an inexhaustible supply of that sponge in a healthy condition. Sponges are very difficult to transplant and keep in aquaria, and the problems greatly increase if while you are trying to keep your sponge healthy, the nuidbranch is doing what it is supposed to - biting chunks off the sponge.

Dear Guido & Philippe,
Thanks for these valauable photos which show the food sponge of this species. I am pretty sure the juvemile in the lower photo is C. elisabethina. I suspect the apparent punctate pattern in the blue area, which makes it looks like C. annae, is a juvenile feature with the mantle still not completely pigmented. The sponge is a I think a species of Petrosaspongia on which the species is often found feeding. I suspect the large hole in the top of the colony has been greatly enlarged by the large spider crab which seems to be protecting it rather fiercely.

Hi Bill,
After reading about C. willani feeding I remembered a photo I took while at Hideaway Island in Vanuatu. It clearly shows C. willani and C.elisabethina feeding.

gary@cobb.com.au
Thanks Gary,
I could be wrong, but I suspect all these slugs are Chromodoris elisabethina. If you look at other photos on this page you will see that this species ranges in colour from the spectacular blue and orange form to a quite dull colour form in which the colour looks very 'faded'.
Hopefully the sponge should be identifiable. Just as a general remark for contributors looking for sponge photos to send, the ideal set of photos for identifying sponges should include one showing the whole sponge colony, as here, and a closeup to show surface texture. Ideally we also need a sample of the sponge colony as well but that is usually not practical, unless the collector is part of an institutionally supported expedition.
Thanks again,

Chromodoris elisabethina - spelling
May 17, 2003
From: Roberto Sozzani
Dear Bill,
What's the exact spelling for Chromodoris elisabethina? I found often 'elizabethina', also in your forum sometimes is spelled with 'z' instead of 's'.
A Google search gives lot of results with both names, so I don't know which one is the right one.
Thanks in advance.
Roberto Sozzani
roberto.sozzani@fastwebnet.it
Dear Roberto,
I discussed this is an earlier message. On checking back through the Forum I see 3 mispellings have crept through in incoming messages - which I've now corrected. The correct spelling is with an s.
Bergh first used the name Chromodoris elisabethina in 1875, but as it was just in a list with no description it is considered a nomen nudum - 'nude name'. We date the name from 1877, when it is used by Bergh with a description. Russell's very useful Index Nudibranchia (1971) lists the spelling of the name in 1875 as 'elizabethina' but in my copy of Bergh 1875 it is definitely an 's'.
Doris elizabethina Kelaart 1859, is the only possible source of confusion but the description is so poor that we can't be sure what it is - perhaps a dendrodorid.

Dear Dr Rudman,
I am a dive instructor and nudibranch fancier living in Cairns. I love reading your internet info in the Slug Site; trying to learn more about local critters.
I never expected to have any info of my own worth emailing. I read, however, about a Chromodoris lochi travelling solo with an everted penis. I've seen penile stylets sticking out on the bodies of solo nudibranchs from time to time. The most dazzling ones are the bright blue penile stylets of Chromodoris elisabethina; quite striking against an orange mantle. I've seen this in the Cairns to Osprey Reef area & once on a 5 day holiday at Heron Island [Great Barrier Reef, Queensland].

I'm afraid there is nothing more to say. The only possibility is that if you live near the sea and there is a species of sponge living there that is related to its normal food sponge (Dysidea sp perhaps?) then there there is an extremely slight chance that your Chromodoris would eat it. But I do not know what C. elisabethina eats naturally, and am not an expert on your local sponge fauna, so I can't give you any sensible advice.

From: Cody Mott
Dr Bill Rudman had recently answered a question I had on the ID of a nudibranch I now know to be called Chromodoris elisabethina. He mentioned that they aren't suited well for the home aquaria since they eat sponges. Is this definitely true or could I have a related species that eats something else. If not, what can I feed him/her? I'm going to talk to the person which I bought it off of, but I figured it would be good to get an answer from you also.

No I'm not insulted. It's very sensible of you to check what you read on the web as there is an awful lot of rubbish published without any quality control. All I can say is that I am a professional biologist who has spent all his career studying these animals. The Forum is published by the Australian Museum and contrary views are welcomed and published. With about 450 people visiting the Forum each day, if anyone disagrees with what I say then I usually get a message to that effect within a day or so.
The only way to really check is to either consult another expert or have a look at some books or scientific journals. If you go to the Species List and look at some of the pages on chromodorids you will find references to various scientific publications. Also have a look at the Book Review section for some books which may be of value to you.
Basically all nudibranchs are carnivores, and most are very specialised feeders. All chromodorids (including Chromodoris, Hypselodoris, Glossodoris) are sponge feeders, each species having its own preferred sponges. As I said in answer to your last message, have a look at the discusssion on the Hypselodoris bullocki pages where this very problem of what to feed them has been going on for a couple of years.
Basically your aquarium shop owner just doesn't know what they eat or has been misled by his supplier. Either way, there is no easy answer to your problem. As far as I know there is no artificial substitute.

The animal at the top of the page is Chromodoris elisabethina. If you go to that page, by clicking on the underlined name, you will find some information about it.
All chromodorids feed on sponges, and in particular those that are without siliceous spicules. Unfortunately I can't tell you which species C. elisabethina prefers although it is most probably a species of Dysidea, Darwinella or Aplysilla. As you will see from the on-going discussion on the Hypselodoris bullocki pages, keeping tropical nudibranchs in aquaria is usually a case of slowly starving them to death. If the shop owner tells you they eat algae he either doesn't know what he is talking about or is lying. If tropical fish were very specialised feeders and impossible to feed in captivity there would be a public outcry against their sale to aquarium hobbyists. I think it is the responsibility of the aquarium trade to find a substitute food for these animals before they start profitting from their sale and ultimate starvation.

Seems like you had an interestng visit to the Great Barrier Reef. In any chromodorid beauty contest Chromodoris elisabethina would certainly be amongst the medals.
At the risk of sounding pedantic, I have corrected your spelling of the name 'elizabethina' to 'elisabethina'. Bergh used the 'z' version invalidly in 1875, but in the first valid description (1877) he spelt it with an 's'. To any English speaker, where Elizabeth is usually spelt with a 'z' it is a trap.
