Seagrass sea hare
Phyllaplysia sp.*
Family Aplysiidae
updated May 2020
Where seen? This tiny slug is sometimes seen in numbers on Tape seagrass on our Southern shores.

Features: 1cm or less. Long narrow, flat body. It has two pairs of tentacles and tiny black eyes. Some seen were translucent green with fine white lines. The internal organs show through as white or yellow blobs or strings. One was seen was solid green. Another had colours and patterns that perfectly matched the encrusted Tape seagrass. Sometimes, extremely tiny ones are seen among bigger ones.

What does it eat? 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.
