Linopherus is a genus of polychaetes belonging to the family Amphinomidae. [1] [2]
The genus has cosmopolitan distribution. [2] They are common in shallow tropical and subtropical waters, but species have been described also from abyssal and polar areas. [3]
The following species are recognised: [1] [2]
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.
Aphrodita is a genus of marine polychaete worms found in the Mediterranean Sea and the Atlantic Ocean.
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.
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.
Janua is a genus of polychaetes, containing the following subgenera and species:
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.
Amphinomidae, also known as the fireworms, 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.
Ceratonereis is a genus of polychaete worms from the family Nereididae.
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 worldwide to depths of about 1200 m but are more common in shallower water.
Aglaophamus is a genus of free-burrowing nephtyid worms.
Marphysa is a genus of annelids belonging to the family Eunicidae.
Scalibregmatidae is a family of polychaetes belonging to the order Opheliida, and was first described by Anders Johan Malmgren in 1867.
Prionospio is a genus of annelids belonging to the family Spionidae.
Orbinia is a genus of polychaetes belonging to the family Orbiniidae.
Amphinome is a genus of polychaetes belonging to the family Amphinomidae.
Lumbrineris is a genus of polychaetes belonging to the family Lumbrineridae.
Notoproctus is a genus of marine polychaete worms in the family Maldanidae. It is the only member of the subfamily Notoproctinae.
