Tropical Indo-West Pacific
Coffs Harbour Region, New South Wales, December 1990, C164622. PHOTO: Bill Rudman.
The mantle is a pale pink with a broad cream-white or yellowish band at the edge. There is an elongate white streak in the midline between the rhinophores and another in front of the gills. Around the anterior and posterior ends and twice down each side of the mantle, the inside edge of creamy yellow border is excavated out and replaced by a washy purple patch. The gills and rhinophores are tinged with orange.
See the Noumea purpurea Colour Group Page to compare this species with others of similar colour.

Yes this is D. pusilla. As you will have seen on the Noumea purpurea Colour Group Page there are a number of other species which can be confused with this species. Compared with Hugues Flodrops animal, the gills of yours are the typical colour pattern.

As the page on the Noumea purpurea Colour Group illlustrates, there are a number of species with very similar colour patterns. The only way to resolve some identification puzzles is to look at their internal anatomy. Certainly the gill colour in your specimens, with an orange base and a purple tip is unusual for Durvilledoris pusilla, but I know of no other species with the same pattern of pink 'tongues' with purple edging extending out into the yellow mantle margin. It would be valuable if anyone with photos of this species could check to see if they have a photo of an animal showing an 'intermediate' gill colour.
Interestingly, this gill colour reminds me of that found in Durvilledoris lemniscata. I am pretty sure Scott Johnson's animal which I have on the Forum as Durvilledoris cf pusilla, is an extreme form of your animal.

When I first saw this small animal I didi not notice the rhinophores, but when I looked more carefully I noticed their strange Y-shape.

I particulalry wanted to share the photos with you.

Thanks for these photos. It is a strange abnormality. I wonder if it is twice as efficient at smelling its food?

Found this little one last weekend. Is it a Durvilledoris pusilla?

Dear Dr Rudman,
I would appreciate your help in identifying this tiny nudibranch (about 1 cm in length) found at the Fan Garden divesite near Wakatobi in about 18 m of water. Its shape looks similar to that of Chromodoris fidelis, it even has the blue fringe between the two colour areas, but of course the colours are inverted, with the reddish tone inside and the creamy tone in the outer part of the mantle and in the foot.
The picture was taken on 15 September 2005.
Thank you so much.

This is Durvilledoris pusilla. If you have a look at the Noumea purpurea colour group Fact Sheet you will see this colourful animal is just one of a group of similarly coloured species

Thanks Nishina & Chikako,
One good thing about studying opisthobranchs, is that we will never run out of beautiful and amzing things to look at

I found this Durvilledoris pusilla yesterday. It was very small at about 15mm. it was on algae covered dead coral at about 8 meters.
Is 15mm the full adult size?, or was it still only juvenile? It was moving along lifting the front edge of its mantle rythmically like a Risbecia does.
I found it at a site just outside of Honiara in the Solomon Islands. For the past couple of years this has been a brilliant Nudibranch site, but it has been damaged by big seas during the past wet season, and there are not so many Nudibranchs around just now.

I hope your nudibranch site doesn't take too long to recover. Concerning size, I'm sorry I haven't any dimensions for Durvilledoris pusilla on the Forum - an oversight. Species of Durvilledoris are quite small, and 15-20mm would be about the maximum length this species reaches.
