Diopatra is a genus of polychaete worms in the family Onuphidae.
Members of this genus live in thick, parchment-like tubes that project from the sediment on the seabed. The tubes are covered on the outside by fragments of shell, algae, fibers and other small objects, collected by the worm and stuck in place by mucus. The worm's tube is a food-catching tool that creates a small micro-reef where small invertebrate prey reside. Diopatra dart partially out of the tube and grasp the prey with their maxillae and mandibles. Their large anterior parapodia help them to immobilize the prey. [2]
The World Register of Marine Species includes these species in the genus. [1] A 2021 study also identified 4 new species in the south-west Atlantic. [3]
The genus Glycera is a group of polychaetes commonly known as bloodworms. They are typically found on the bottom of shallow marine waters, and some species can grow up to 35 cm (14 in) in length.
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 Eastern and Western Atlantic Oceans.
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.
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.
The Onuphidae are a family of polychaete worms.
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.
Lysidice is a genus of polychaete worms in the family Eunicidae.
Cirriformia is a genus of marine polychaete worms in the family Cirratulidae.
Eulalia is a genus of polychaete worms.
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.
Aglaophamus is a genus of free-burrowing nephtyid worms.
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.
Thelepus is a genus of polychaetes belonging to the family Terebellidae.
Lumbrineris is a genus of polychaetes belonging to the family Lumbrineridae.
Onuphis is a genus of polychaete belonging to the family Onuphidae.
Diopatra claparedii is a species of tube-building polychaete worm of the family Onuphidae. It is found dispersed along intertidal and subtidal benthic environments of South Asian waters, especially along the coasts of Malaysia, Singapore, Thailand, and the Philippines. This species is exploited by humans for fishing bait, indication of marine pollution, and as gold and silver nanoparticle biosynthesis agents.
