<i>Nereis</i> Genus of annelid worms

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.

Spirobranchus is a small genus of tube-building annelid fanworms in the family Serpulidae.

<i>Pseudoceros</i> Genus of flatworms

Pseudoceros is a genus of the flatworms Platyhelminthes.

<i>Pseudobiceros</i> Genus of flatworms

Pseudobiceros is a genus of flatworms. Like all flatworms, Pseudobiceros are hermaphrodites. This particular genus engages in penis fencing. When the "winner" touches its penis to the "skin" of the other, insemination occurs, and the "loser" has to bear the burden of motherhood.

<i>Phyllodoce</i> (annelid) Genus of annelids

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.

Errantia Subclass of annelid worms

Errantia, occasionally Aciculata, is a subclass of polychaete worms. These worms are found worldwide in marine environments and brackish water.

<i>Amphinomidae</i> Family of annelids

Amphinomidae, also known as the bristle worms or sea mice, are a family of marine polychaetes, many species of which bear chaetae mineralized with carbonate. The best-known amphinomids are the fireworms, which can cause great pain if their toxin-coated chaetae are touched or trodden on. Their relationship to other polychaete groups is somewhat poorly resolved.

Acotylea Suborder of flatworms

Acotylea is a suborder of free-living marine turbellarian flatworms in the order Polycladida.

Bispira is a genus of marine bristleworm in the family Sabellidae. Its members were initially included in genus Sabella by Grube in 1851. In 1856, Krøyer described Bispira as a separate genus. Members of Bispira are defined by spirally-coiled, equally-divided branchial lobes.
