Phyllodesmium nudibranch
Phyllodesmium sp.
Family Facelinidae
updated May 2020
Where seen? This 'hairy' nudibranch is sometimes seen on some of our shores. It is seen near reefs in the South as well as rocky areas in the North.

Features: About 2cm long. Long, narrow, soft body with
many long finger-like structures (called cerata) arranged in rows across the body. The body and cerata nurture the symbiotic zooxanthellae that continues to undergo photosynthesis and produce nutrients within the sea slug. Usually beige or brown.

What does it eat? According to Bill Rudman, Phyllodesmium briareum feeds on Fine feathery soft corals (Briareum sp.).
