Phyllodocida

Nereididae (formerly spelled Nereidae) are a family of polychaete worms. It contains about 500 - mostly-marine - species grouped into 42 genera. They may be commonly called ragworms or clamworms.

Phyllodocida is an order of polychaete worms in the subclass Errantia. These worms are mostly marine, though some are found in brackish water. Most are active benthic creatures, moving over the surface or burrowing in sediments, or living in cracks and crevices in bedrock. A few construct tubes in which they live and some are pelagic, swimming through the water column. There are estimated to be more than 4,600 accepted species in the order.

Aphroditidae is a family of annelids belonging to the order Phyllodocida.

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.

Polynoidae is a family of marine Polychaete worms known as "scale worms" due to the scale-like elytra on the dorsal surface. Almost 900 species are currently recognised belonging to 9 subfamilies and 167 genera. They are active hunters, but generally dwell in protected environments such as under stones. The group is widely distributed from shallow intertidal waters to hadal trenches. They are the most diverse group of polychaetes in terms of genus number and second most diverse in terms of species number which is almost 8% of all segmented worm species. thumb| A scale worm moving along the sub

Glyceridae is a family of polychaete worms. They are commonly referred to as beak-thrower worms or bloodworms. They are bright red, segmented, aquatic worms. The proboscis worm Glycera is sometimes called bloodworm. The Glyceridae are epi- and infaunal polychaetes that prey upon small invertebrates. They are errant burrowers that build galleries of interconnected tubes to aid in catching their prey.

Phyllodocidae is a family of polychaete worms. Worms in this family live on the seabed and may burrow under the sediment.

Chrysopetalidae is a family of polychaete worms. The body is short or elongated, with few or numerous segments. All segments bear on their dorsal side a fan or a transverse row of paleae. The cephalic lobe has tentacles and eyes and the buccal segment has two or four tentacular cirri on each side. The parapodia are uniramous or biramous, with dorsal cirri upon all segments. The ventral bristles are compound.

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 (Practical Salinity Units).

Sphaerodoridae is a family of polychaetes belonging to the order Phyllodocida.

Hediste is a genus of annelids belonging to the family Nereididae.

Alciopidae, also known as the "Camera Eyed Worms" is a family of polychaetes belonging to the order Phyllodocida. Alciopids are notable for representing the fourth phylum — besides arthropods, chordates, and mollusks — to have evolved high-resolution vision, namely vision that can distinguish objects from the visual background, enabling interaction with said objects. This has been demonstrated in particular in Vanadis cf. formosa, Torrea candida, and Naiades cantrainii.

Alitta is a genus of marine annelids in Nereididae family (commonly known as sandworms or ragworms). There are three recognised species within the genus, Alitta grandis (Stimpson, 1853), Alitta succinea (Frey & Leuckart, 1847) and Alitta virens (M. Sars, 1835). Alitta brandti Malmgren, 1865 was originally considered part of the genus, but is now accepted as Neanthes brandti (Malmgren, 1865).

Goniadidae is a family of marine worms within the Polychaeta. Goniadids have long, slender bodies and can grow up to 260mm in length, although most are less than 50mm long. Goniadids have an eversible proboscis with a circlet of chitinous jaws around the terminal end.
