Characteristics
Sigalionids are scale worms with long, narrow bodies, and provided with numerous segments, 15–300, and pairs of elytra. The surface of the elytra may display tubercles, papillae or other ornamentation. The dorsal cirri are only present on segment 3, and unlike Polynoidae and other scale worms, sigalionids have compound chaeta on the neuropodia.
