Gunnarea is a monotypic genus of polychaete worms in the family Sabellariidae, first described by Karl Eric Johansson, in 1927. The type taxon is Hermella capensis Schmarda, 1861 now accepted as syn. Gunnarea gaimardi (Quatrefages, 1848). [1] [2]
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.
The Prolecithophora are an order consisting of an estimated 300 species of small, active, aquatic flatworms. The order lacks a common English name. Most species are shaped like an elongated, stylized droplet, and are opaque white or yellow; they frequently have contrasting bands or spots in colors, such as purple, yellow, red, or brown. They have no to three pairs of pigment-cup eyes, and well-developed tactile and chemoreceptor senses. With few exceptions, species are protandric hermaphrodites with internal fertilization. Egg capsules are, according to species, glued to various hard surfaces; the young hatch as miniature copies of their parents.
Ludwig Karl Schmarda was an Austrian naturalist and traveler, born at Olmütz, Moravia.
Spirobranchus is a small genus of tube-building annelid fanworms in the family Serpulidae.
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.
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.
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.
Cirriformia is a genus of marine polychaete worms in the family Cirratulidae.
Cirriformia capensis, commonly known as the orange thread-gilled worm, is a species of marine polychaete worm in the family Cirratulidae.
Chloeia is a genus of marine polychaete worms.
Eulalia is a genus of polychaete worms.
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.
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.
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.
Eurythoe is a genus of polychaetes belonging to the family Amphinomidae.
