Favorinus sp. 5
Found in egg mass of sand-dwelling haminoeid. Bali, Tulamben, 9m; 1 November 1998. Upper: 4mm long. Lower: (in egg mass) size ? Photos: Clay Carlson.
One of a number of aeolid species which live and feed inside the opisthobranch egg masses they are feeding on. I have tentatively placed them all in the genus Favorinus, because of their general shape and their egg-eating habit.
