Another Chromodoris at Moloolaba

March 3, 1998
From: Wayne Ellis

Hi Bill,
The new site looks great. Looking forward to using it. Found four small (10mm) nudis
Location: Point Cartwright, Mooloolaba, southern Queensland. Depth: intertidal.
Description: Fits the description of Chr. decora (Pease,1860) (No 71 in Willan and Coleman's book Nudibranchs of Australasia, 1984). The picture does not do it justice.
Remarks: Two were found together and one alone. All under rocks on a black encrusting sponge (I think). There were signs where the sponge had been eaten where the two were found. A black encrusting sponge is common at this site.
Regards
Wayne Ellis

Wayne,
Thanks for the information about a possible sponge food of Chromodoris decora. It's a slow job building up information on diets. While some species are always found on their food, others aren't so helpful. We have no good evidence for this species. I have a photo from Nathalie Yonow of Chromodoris decora from the Red Sea crawling alongside a blackish encrusting sponge so you may be on to something. Please keep an an eye out for more 'evidence'... Bill Rudman
