Concerning message #19989:

Hi Bill,
Thanks for the response on the query of H. rudmani vs H. sagamiensis. I want to continue to accept that they are 2 different species, so I will try to get as many photos as I can on these. Here is one from my files which I think conforms more with the description of the H. rudmani. It spent a long time on the red coloured object. I am very weak on identification of sponges, so I dont know what it was investigating.

Locality: Sodwana Bay, 20 metres, South Africa, Indian, June 2006, reef. Length: 20mm. Photographer: Colin Ogden.

regards

Dear Colin,
Firstly, I have spent a long time looking at the 'red-coloured object' and am pretty sure it is a compound ascidian rather than a sponge, so not likely to be of significance.

Concerning the nudibranch, there are not too many species with black spots on translucent patches like this. The only one that seems to fit is Chromodoris sp 14  from Japan which is a long way from South Africa.

Best wishes,
Bill Rudman
