Chromodoris mandapamensis feeding ?

February 15, 2007
From: Colin Ogden

Hi Bill,
The other day I came across a Chromodoris mandapamensis that appeared to be feeding. I know we are looking for some pictures of what type of sponge they are feeding on. After taking the upper photo I moved its head and tried to get a picture of the area it was interested in. I can not determine what it was feeding on from my photos. It appears to be something small hidden under the growth. This seems to be the case with all the photos we try to get of this animal feeding. I am sending you these pictures in the hope that you can find something I have overlooked.

Locality: Sodwana Bay, 19 metres, South Africa, Indian, 13 January 2007, reef. Length: 45 mm. Photographer: Colin Ogden

Dear Colin,
Thanks for persevering with this mystery. All I can say is that some day you must have success. I looked closely at your original photos (which I have cropped a bit) and could find no sign of a sponge. If this species is, as I suspect, a colour form of C. striatella then I would suspect that like that species, it will be feeding on a darwinellid sponge [see earlier message [#9559 and Fact Sheet]. It should also have a flat egg ribbon [message #19123 ].

Good luck,
Bill Rudman
