This animal has similarities to an aeolid, a Janolus and a sacoglossan. See the discussion in the messages below. The consensus seems to agree that it is a sacoglossan, and the close set eyes suggest a species of Costasiella. Points of importance are grooved rhinophores, the eyes close together, the 'melanin gland' (black spot behind the eyes and in front of the pericardial sac).
