Species: [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. 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. They are dangerous to touch giving very painful long lasting burns. Nereis worms are commonly known as rag worms or clam worms. The body is long, slender, and dorso-ventrally flattened, reaching a length of 5-30 cm. The head consists of two parts: a roughly triangular anterior lobe—the prostomium—and a posterior ring-like portion—the peristomium. The latter bears a pair of terminal tentacles, dorsally two pairs of eyes, and ventrally a pair of short two-jointed palps.
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.
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.
Acrocirridae is a family of polychaete worms. Acrocirrids are detritivores, catching falling particles with numerous long prostomial tentacles. There are eight known genera, and at least 21 described species and subspecies within the Acrocirridae. The acrocirrids are primarily benthic (seabed-dwelling) animals, but at least two genera appear to have evolved or adapted to a pelagic (free-swimming) habitat.
Phyllodoce is a genus of polychaete worms, which contains about 200 species. The prostomium bears eyes, two pairs of antennae and a pair of large retractile nuchal organs. The eversible proboscis is clearly divided into two parts.
Diopatra is a genus of polychaete worms in the family Onuphidae.
The Euphrosinidae are a family of polychaete worms. The name is from Greek Euphrosyne, meaning merriment; she was one of the three Graces.
Dodecaceria is a genus of marine polychaete worms in the family Cirratulidae.
Cirriformia is a genus of marine polychaete worms in the family Cirratulidae.
Eulalia is a genus of polychaete worms.
Lepidasthenia is a genus of marine Polychaete worms belonging to the family Polynoidae. Species of Lepidasthenia are found world-wide to depths of about 1200 m but are more common in shallower water.
Lepidonotus is a genus of marine annelids in the family Polynoidae. The genus occurs globally and includes 80 species, usually found in shallow waters down to about 80 metres.
Thelepus is a genus of polychaetes belonging to the family Terebellidae.
Cirratulus is a genus of annelids belonging to the family Cirratulidae.
Odontosyllis is a genus of annelids belonging to the family Syllidae.
Armandia is a genus of polychaetes belonging to the family Opheliidae.
Eumida is a genus of polychaetes belonging to the family Phyllodocidae.
Linopherus is a genus of polychaetes belonging to the family Amphinomidae.
Lumbrineris is a genus of polychaetes belonging to the family Lumbrineridae.
