Accepted genera: [1]
Nereis is a genus of polychaete worms in the family Nereididae. It comprises many species, most of which are marine. Nereis possess setae and parapodia for locomotion and gas exchange. They may have two types of setae, which are found on the parapodia. Acicular setae provide support. Locomotor setae are for crawling, and are the bristles that are visible on the exterior of the Polychaeta. They are cylindrical in shape, found not only in sandy areas, and they are adapted to burrow. They often cling to seagrass (posidonia) or other grass on rocks and sometimes gather in large groups.
The Terebellidae is a marine family of polychaete worms, of which the type taxon is Terebella, described by Carl Linnaeus in his 1767 12th edition of Systema Naturae.
Ampharetinae are a subfamily of terebellid "bristle worm". They are the largest subfamily of the Ampharetidae, of which they contain the great majority of the described genera.
Ampharete is a genus of polychaete annelid worms. They have a single, chevron-shaped row of teeth.
Scalibregma inflatum, also known as T headed worm, is a burrowing marine polychaete. It is a cosmopolitan species that can be found from the Arctic to Antarctica, although most probably several species are confounded.
Phyllodocidae is a family of polychaete worms. Worms in this family live on the seabed and may burrow under the sediment.
Bylgides is a genus of marine annelids in the family Polynoidae. The genus contains 9 species, all found in the Northern Hemisphere and from shallow inshore waters to depths of about 5000 m.
Gattyana is a genus of marine annelids in the family Polynoidae. The genus includes 11 species, 9 of which occur in the northern hemisphere, the remaining two are from the Indian Ocean off Mozambique and the Southern Ocean off New Zealand. Species of Gattyana are known from shallow water down to depths of about 1200 m.
Gattyana amondseni is a scale worm described from the Arctic and North Atlantic Oceans at depths down to about 700 m.
Ceratocephale is a genus of polychaetes belonging to the family Nereididae.
Capitellida is an order of annelids belonging to the class Polychaeta.
Maldanidae is a family of more than 200 species of marine polychaetes commonly known as bamboo worms or maldanid worms. They belong to the order Capitellida, in the phylum Annelida. They are most closely related to family Arenicolidae, and together form the clade Maldanomorpha.
Paraonidae is a family of polychaetes belonging to the order Cirratulida.
Opheliida is an order of polychaetes belonging to the class Polychaeta.
