This photograph was taken on September 7, 1998, at Curphy Reef, not far from Crowdy Head in northern New South Wales, at a depth of about 18m. This nudibranch was approximately 1cm long. Do you know the species?

No I don't recognise this animal. It looks as though it is probably a species of Noumea. Was it found on the sponge it is photographed on? If so it is a quite interesting find. Most chromodorids feed on relatively soft sponges which lack skeletal spicules. One species endemic to New South Wales, Hypselodoris bennetti, feeds on a sponge, Psammocinia sp (Thorectidae, Dictyoceratida) which has a skeleton consisting mainly of sand grains. If your animal was living on the sponge inthe photo, it also looks like one with a sand-grain based skeleton.
