Harmothoe
''Harmothoe'' is a genus of marine Polychaete worms belonging to the family ''Polynoidae'' (scale worms). Species of ''Harmothoe'' are found world-wide to depths of at least 5,000 m but are more common in shallower water. Description Body dorsoventrally flattened, short, with 15 pairs of elytron (Annelida), elytra and up to 50 segments; the body is more or less covered by elytra, although long specimens may have a short posterior region uncovered. The prostomium is rounded anteriorly and has distinct cephalic peaks on the dorsal surface. There are three antennae, a pair of lateral antennae inserted ventrally, directly beneath the median antenna ceratophore. The Parapodia, neuropodia are elongate and tapering. The Chaeta, notoochaetae are stout with transverse rows of spines and blunt tips. The Chaeta, neurochaetae also have transverse rows of spines and both unindentate and bidentate neurochaetae are present.Barnich R, Fiege D (2000) Revision of the Mediterranean specie ...
