Common cerianthid
awaiting identification*
updated Oct 2016

Where seen? This cerianthid is commonly seen on our Northern shores, sometimes in large numbers and often in a variety of colours and patterns. On silty sand as well as among seagrasses and sometimes near coral rubble.

Features: 10-15cm in diameter. The long tentacles are rather fat and taper to a narrow tip. The ring of shorter inner tentacles are sometimes different in colour from the long tentacles. Some are plain, others have variegated long tentacles. Body column usually pale. Little black Phoronid worms are often seen with them.
