Chromodoris willani feeding?

December 6, 2005
From: Asther Lau

Hello Bill!

Attached are images of a Chromodoris willani on a species of sponge coral. I think this coral is one of its food but have no pic proof it. Throughout this single dive, I found a few more of this nudi, also "sticking" on the same sponge species.

Locality: Sipadan Island, Malaysia, Sabah, Malaysia, Celebes Sea. Depth: 16 metres. Length: 2 cm. March 13, 2004. Wall of Coral Reef. Photographer: Asther M. Lau

Hope this is informative for the Forum.

Dear Asther,
Thanks very much for this observation. Getting information on the biology of these animals is not always easy. Obviously actually catching them feeding with their oral tube everted, or with their head in a freshly excavated hole, are the ideals, a good second best is to build up information on regular associations with a particular food. Even though you have not actually witnessed feeding, your observations fit a number of other observations on the Forum of a close association between C. willani and this sponge.
Best wishes,
Bill Rudman
