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.
Nereididae are a family of polychaete worms. It contains about 500 – mostly marine – species grouped into 42 genera. They may be commonly called ragworms or clam worms.
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.
Nephtys is a genus of marine catworms. Some species are halotolerant to a degree in that they can survive in estuaries and estuarine lagoons down to a salinity of 20 psu.
Harmothoe is a genus of marine Polychaete worms belonging to the family Polynoidae. Species of Harmothoe are found world-wide to depths of at least 5,000 m but are more common in shallower water.
Eunice is a genus in the polychaete family Eunicidae. Individuals grow to a length of between 0.5 and 300 cm. Their bodies have multiple segments. They have two eyes and five tentacles. They have well-developed sense organs and relatively large brains. Their color is dark purple-brown to red-brown with a white ring at the fourth segment. They are found in oceans and seas around the world. They have an evertible proboscis with distinctive mouthparts, some of which comprise two rows of maxilliary plates in a radula-like fashion.
Diopatra is a genus of polychaete worms in the family Onuphidae.
Syllidae, commonly known as the necklace worms, is a family of small to medium-sized polychaete worms. Syllids are distinguished from other polychaetes by the presence of a muscular region of the anterior digestive tract known as the proventricle.
Bathyeliasona is a genus of marine annelids in the family Polynoidae. The genus includes 4 abyssal and bathyal species which occur widely in the Atlantic, Pacific and Indian oceans, from depths of 2500 to 8000 m.
Bathyeliasona abyssicola is a deep-sea scale worm which occurs widely across the Pacific and Atlantic Oceans and over a wide depth range, from 4000m to 8000m.
Bathyeliasona kirkegaardi is a deep-sea scale worm which is only known to occur in the Pacific Ocean, where it is recorded from a depth range of about 5,500–8,000 m.
Bathyeliasona nigra is a deep-sea scale worm which occurs widely in the Indian, Pacific and Atlantic Oceans from a depth range of about 2,500-5,000m.
Austrolaenilla is a genus of marine annelids in the family Polynoidae. The genus includes 10 species which are known from depths of about 20 m to over 5000 m and from the Atlantic Ocean, Southern Ocean and Antarctic Ocean.
Oxydromus is a genus of annelids belonging to the family Hesionidae.
Marphysa is a genus of annelids belonging to the family Eunicidae.
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.
Iphionidae is a family of polychaetes belonging to the order Phyllodocida.
Scolelepis is a genus of annelids belonging to the family Spionidae.
Chone is a genus of polychaetes belonging to the family Sabellidae.
Lumbrineris is a genus of polychaetes belonging to the family Lumbrineridae.
