Common name: Scale Worms
Scientific name: Polynoidae
Polynoidae, commonly known as scale worms, are a family of polychaete worms characterized by their distinctive overlapping scales, or elytra, which protect their dorsal surfaces. These worms are found in a variety of marine environments, from intertidal zones to the deep sea. In reef aquariums, some scale worm species can be beneficial scavengers, consuming detritus and helping to keep the substrate clean. However, hobbyists should be cautious as some species may prey on small invertebrates or corals. Identification of the specific species and understanding their behavior is crucial before introducing them to a reef tank.
