Spirorbis spirorbis is a small (3-4 mm) coiled polychaete that lives attached to seaweeds and eel grass in shallow saltwater. They have a smooth, white, sinistral (left-handed) coiled shell encasing an orange body about 3 mm in length. The tube has a peripheral flange where it attaches to the substrate. The worm has a short abdominal region and a slightly broader thorax terminating in ten stiff tentacles, used to filter food from the water. One of the tentacles is slightly larger than the rest and shaped like a saucer, which is used as an operculum. This seals the opening of the shell and serves to protect the worm from predators and desiccation when out of water.
