Hi Bill-Happy New Year.
Never had the good fortune to visit the Indian Ocean, but in Hawaii, at least, E. rufescens eats Bryopsis pennata and, from limited collecting experience, is rarely found very far away from it. We have found Bryopsis plastids in the digestive cells of E. rufescens (not published). however, although they retain plastids - I think they are not very good at it. Notice the color of the slug in these pictures is brownish, rather than green. Again from limited experience with them, that is pretty standard. Finally, the external morphology between these and the Hawaiians seems very similar.
