Polynoids are a very diverse group of benthic marine worms. They are characterised by having simple chaetae both in the noto- and neuropodia, and the dorsum is covered by scales, often brightly pigmented, alternating with dorsal cirri. Because of these scales, they are called scale worms. They are carnivorous or omnivorous and several species are commensal with other organisms.
