Spirographs are marine worms of the Sedentary Polychaeta class, belonging to the phylum of the Anellids. They live inside a tube of paper or calcareous consistency produced by the animal itself in which it withdraws in case of danger. The cephalic area is equipped with filiform gills covered with eyelashes and mucous glands, whose function is to pick up food particles. In fact it is a typical filtering animal that feeds on suspended plankton.
