Habitat information icon Habitat information The calcareous tubes of Serpula vermicularis can be found attached to hard substrata such as rocks, stones, bivalve shells and ship hull's from low water to the sublittoral in depths up to 250 m. In some very sheltered areas the tubes aggregate together to form small reefs.
Text page icon Description Serpula vermicularis is a slender, tube-dwelling polychaete between 5 and 7 cm in length with about 200 segments. The tubes are cylindrical with occasional rings and irregular lengthwise ridges cut into blunt teeth. The operculum is calcareous and funnel shaped with radial grooves and a serrated circumference. The colour of the body of the worm varies from pale yellow to brick red. The tube is pinkish-white and the operculum is patterned with red and white rays.
