Wayne,
This is one of a number of unnamed species of Janolus which are known from Australia. Despite looking like aeolid, with cerata covering their backs, species of Janolus (and the related Madrella and Caldukia) are more closely related to the arminids. They feed on both branching and encrusting bryozoans (lace corals) and it is likely that different species have specific bryozoans they prefer as food. The species in your photograph is known from the Great Barrier Reef and as far south as central New South Wales. It is also reported from Lord Howe Island and New Caledonia.... Bill Rudman
