These marine worms are commonly seen around the world in the intertidal zone down to 100 m. They form calcareous tubes which are attached to hard substrates. The worm emerges from the tube to feed with a delicate plume of feather-like radioles, catching plankton and detritus. The radioles also act as gills. A funnel-shaped operculum covers the animal when it retracts into the tube for protection. Gouache and watercolor on tinted paper. Artwork by Fiona Martin, Visualizing Science.
