Chromodoris dianae from Nth Sulawesi

January 26, 2007
From: Mirjam Broos


Dear Bill,

I can't decide whether this is Chromodoris lochi or Chromodoris dianae. Although the gills seem to have one color, the blue mantle shows white specks. Can you help me with this please?

The first picture was taken at Lekuan 2, the other two at the divespot Tanjung Parigi, both in Bunaken.

Locality: Bunaken, North Sulawesi, Indonesia, 03 October 2006, coral wall. Photographer: Geert Prast.

Thanks,
Mirjam

Dear Mirjam,
These are on eof the colour forms of C. dianae. The lower  two photos are a good example of the difficulties involved in finding the food sponge of these animals. When you find a group of them clustered like this, all facing the same way you can be preety sure that food rather than sex has drawn them together. However, as often is the case, the substrate is overgrown with algal encrustations, sponges, bryozoan or hyroid colonies etc, and so there is no way from the phtos to know just what they are interested in, let alone identify it

Best wishes,
Bill Rudman
