Chromodoris heatherae feeding

Thanks Charles,
It certainly seems to be interested in this orange sponge but a bit hard to be sure. The little purple and orange amphipods are quite spectacular. I'm interested in the habits of all opisthobranchs, but the reason I was particularly interested in the feeding habits of this species was that C. heatherae appears to have a rather distinct colour form which lacks a yellow border. Without comparing the anatomy of animals with and without this border I thought it might be useful to see if there were consistent behavioural differences between yellow-bordered and borderless animals. Perhaps the different colour forms ate different sponges? If so, this might suggest we had two different but very similarly coloured species like the many red-spotted species in southeastern Australia
