updated Oct 2016
Where seen? This tiny slug is sometimes seen in numbers on Tape seagrass (Enhalus acoroides).

Features: 1cm or less. Long narrow, flat translucent body with fine white lines. With two pairs of tentacles. It seems to graze on algae and/or other encrusting organisms growing on the seagrass blades as the area around the slug is often 'clean' of encrusting growths.
