Dear John,

Tasmania has a multitude of chromodorid species with orange and red spots so you are correct to be cautious. It certainly looks like it could be one of the yellow species from that region [see Noumea flava colour group] and the orange spots with white around them look quite like N. closei.

However I am pretty sure this is another species, Chromodoris multimaculosa, which until now I haven't added to the Forum.  If your cluster of 5? animals is this species, then you have almost doubled the number of known specimens and given us an indication of the sponge it feeds on.

Best wishes,
Bill Rudman
