Sabellaria
''Sabellaria'' is a genus of marine polychaete worms in the family Sabellariidae. The type species is ''Sabellaria alveolata'' (Linnaeus, 1767). These worms are sedentary and build tubes in which to live from sand and shell fragments. Some species are called honeycomb worms and when they occur in great numbers they can form reefs on rocks and other hard substrates. They are filter feeders, extending a plume-like fan of radioles from the end of the tube in order to catch plankton and detritus floating past. They have a distinctive operculum which is used to block the opening of the tube when the radioles are retracted. JNCC. Retrieved 2011-11-02. Species The following |
Sabellariidae
Sabellariidae is a family of marine polychaete worms in the suborder Sabellida. The worms live in tubes made of sand and are filter feeders and detritivores. Characteristics Members of this family live in tubes made of sand and shell fragments cemented together and attached to rocks. Some species are colonial and the multitude of their tubes may create hummocks and even reefs. The top of the tube can be closed by an operculum formed by several rings of bristles on the head of the worm. The head also bears several fine feeding tentacles and a pair of small palps. The thoracic section of the body has 3 or 4 segments with paddle-like capillary bristles. The abdominal section has many segments each with hooked bristles on raised lobes. There are a pair of gills on each of the thoracic segments and on the front abdominal segments. The rear of the body is bent forward along a groove in the midsection of the body.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...
