Chromodoris cf. roboi from Indonesia

November 14, 2001
From: Stuart Hutchison

Hi again Bill,
long time no communicate! Mel and I have just come back from another fruitful trip to Tulumben, Bali, Indonesia. We found more different nudibranchs than ever before on this trip (I have photos of about 80 different species now). However, we haven't been able to find this guy in any of the good books (including Neville's latest).

Found at 45m depth (where there were lots of the regulars like Risbecia tryoni and Hypselodoris maculosa) on 16th Oct 2001, this one was about 35mm long, on the move in the coral garden (mostly small coral boulders, barrel sponges, hydroids and fans in the area) and the colours are pretty much reversed (missing some mantle colouring too) from Chromodoris roboi. What do you think??

Regards,
Stuart

Dear Stuart,
An interesting animal. If you have a look at the lower photo on the Chromodoris roboi Page you will see an animal with much the same colour pattern as yours. However yours differs in having yellow gills and rhinophores. I am also not sure how much color variation there is in C. roboi. At the moment I am happy to accumulate photos of any chromodorids with this range of colours. Perhaps a pattern will emerge. In the meantime I will call your animal Chromodoris cf. roboi so that I don't forget its similarity to more 'typically' coloured animals.
Best wishes,
Bill Rudman.
