A large sabellid polychaete worm with a delicate plume variously coloured. The tube stands proud of the bottom by as much as 5 to 10 cm. When the worm retracts the top of the tube rolls up, effectively closing the tube. This worm is parasitized by the tiny snail Evalea tenuisculpta
, which can sometimes be found in large numbers clustered around the end of the tube.
