Heteropsammia cochlea
©Anne: Heteropsammia cochlea is extremely common in water deeper than 13 metres in Watson's Bay. It is the most common member of a unique assemblage of solitary corals in this area. In this photo, there is also one specimen each of Cycloseris cyclolites and Heterocyathus aequicostatus.
©Anne: A sipunculan worm, Aspidosiphon (Aspidosiphon) muelleri, is an obligate commensal with Heteropsammia cochlea. It lives inside the skeleton and can extend its proboscis through a hole in the base of the coral to move the coral and prevent it from becoming buried.
