Notes compiled from Brunckhorst, 1993:
Phyllidiopsis shireenae is distinctive, on account of its mid-dorsal crest (i.e., the body is not dorsoventrally flattened as in other phyllidiids), very pale pink coloration with a few black lines, and salmon pink rhinophores.
No other phyllidiid possesses a large dorsal crest and salmon pink rhinophores. Phyllidiopsis gemmata is grey-pink to grey-blue with three tuberculate ridges, black rhinophores. Phyllidiopsis krempfi has multicompound pink tubercles, black and pink rhinophores, and possesses 26-28 lamellae on each rhinophoral clavus (17-20 in P. shireenae). Phyllidiopsis pipeki, Phyllidiopsis burni and Phyllidiopsis fissuratus differ from P. shireenae in having large compound tubercles, black and pink rhinophores and pink to grey ventral coloration (white in P. shireenae).

While identifying the phyllids I shot recently on Lady Musgrave Is as P. rudmani, I noted the widely-ranging forms and attach two images in case they are of use in documenting species variability. Rhinophore in one image shows no black tip, but the angle might obscure this - next time I'll know what to look for.

Thanks for the photos. I'm afraid I can't see the rhinophore you mention. From the general shape and colour of the animals I suspect these are Phyllidiopsis shireenae. Unfortunately, photos of the dorsal surface alone are often not sufficient to identify phyllidiids.

David Brunkhorst, when he described this species, had a specimen from Taiwan, and Scott Johnson has reported it from the Marshall Ids [message #2705] so it would have been strange if it did not occur at Palau, but it is good to get a real record.

The shape of the body, with its high dorsal crest, and the pink rhinophores suggest this is P. shireenae. I think we will just have to add a second transverse black line across the mantle as part of the colour variation of this species.

Here is one of the nudibranchs that Charlotte and I found at Pemba Island, off the coast of Tanzania, western Indian Ocean, in November/December 2001. The species from the west coast of Pemba are from dives we did with the Fundu Lagoon Resort to small nearby islands.
Both animals were photographed on 27 November, 2001, on the west side of Pemba, but it was also seen on the east side

Here is a range extensions to East Africa for Phyllidiopsis shireenae. I found it while diving at Pemba Island in Feb 1999. I saw several, large - 60-70mm - animals and they differed from Indonesian ones in being pink rather than white, but the characteristic high ridged body and markings were as normal for this species. I enclose a scan of an Indonesian one from Bali [UPPER] and the Pemba one [LOWER].

Certainly extending its known range from one side of the Indian ocean to the other is a significant range extension. It is interesting how many of the greeny-grey phyllidiids seem to range in colour to pink, often in the same population. Perhaps with further observations the grey form will be found in east Africa and the pink on the Pacific side - in fact I just note that the lower photo of mine on the species Fact Sheet from Pelorus Island, Nth Queensland, has quite a pink tinge.

Phyllidiopsis shireenae lives in Lembeh Strait too. This one was around 10cm long -- about twice the length of any I have seen in Papua New Guinea or the Solomon Islands. It appeared to be dining on orange sponge. I wanted to see what the gills looked like so I turned it over and photographed the ventral side.

As records accumulate it looks like this species is widespread in the tropical Western Pacific and at least the east side of the Indian Ocean.

Yes this is Phyllidiopsis shireenae. For some reason the back half of its body is a bit twisted. I don't know if its from damage or whether its been a bit slow in straightening out after crawling over something crooked.

I just looked at the details on P. shireenae and noted the sizes reported. Checking through our records for sightings last year in the Tukang Besi Archipelago, SE Sulawesi, Indonesia (Operation Wallacea) the largest we found was a 100 mm specimen at a depth of 65 ft while the smallest was 30 mm. I don't have the picture to hand of the largest one but will post it to you when I can.

I should stop being surprised. I can dive an area for years and years, and still new things pop up. Recently it was Phyllidiopsis shireenae, found by Karen DeGroff on the leeward seaward slope of Kwajalein Atoll at a depth of 35 meters (photo e435-2). I believe this is a considerable range extension. The specimen was a bit moribund by the time I took this photo. At 95mm in length, the Marshall Islands animal is larger than several specimens I saw in the Solomons a few years ago. The other photo (s038-5) is a shot of an individual from Guadalcanal, Solomon Ids.

I thought this species was known only from the southwest Pacific but as I was posting your message I note that Brunckhorst has a record from Taiwan, and Erwin Koehler recently sent a photo to the Forum from the Maldives. The Marshall Ids record really takes P. shireenae out into the Pacific, so it is clearly a widespread Indo-West Pacific species.
About new things popping up all the time. I remember in Tanzania being quite disappointed when something new didn't pop up every two weeks or so. I guess there are many opportunistic species which only grow to visible size at a particular place if larvae happen to coincide with the presence of their food, which is probably as equally unpredictable.

It seems their nasty chemicals don't give them complete protection from damage - though I guess it apparently lived to tell the tale. Your find is, I think, a new record from Indian Ocean. It is also a new size record as well.

This is Phyllidiopsis shireenae. The phyllidiids are a family of dorid nudibranchs which have lost their radular teeth, and feed suctorially. Although they are often common we know very little about their biology and on what sponges they feed. They don't have a circlet of gills on their back but have a row of secondary gills along each side of the of the body beneath the mantle skirt. A few years ago David Brunckhorst greatly advanced our knowledge of the family by publishing a monograph reviewing, with colour photos, all the species of the family. I have put details on how to order it in the Book Review section.... Bill Rudman
