Bispira Polyomma
''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. Species According to the World Register of Marine Species, ''Bispira'' contains 31 valid species: * ''Bispira brunnea'' (Treadwell, 1917) * '' Bispira crassicornis'' (Sars, 1851) * '' Bispira elegans'' (Bush, 1905) * '' Bispira fabricii'' (Krøyer, 1856) * '' Bispira guinensis'' (Augener, 1918) * '' Bispira klautae'' Costa-Paiva & Paiva, 2007 * '' Bispira manicata'' (Grube, 1878) * '' Bispira mariae'' Lo Bianco, 1893 * ''Bispira melanostigma'' (Schmarda, 1861) * '' Bispira monroi'' (Hartman, 1961) * ''Bispira oatesiana'' (Benham, 1927) * '' Bispira pacifica'' (Berkeley & Berkeley, 1954) * '' Bispira paraporifera'' Tovar-Hernandez & Salazar-Vallejo, 2006 * '' Bispira polyomma'' ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 taxonomy (biology), 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. Phylogeneti ...

Bispira Volutacornis
''Bispira volutacornis'', sometimes known by the common names twin fan worm or spiral fan worm, is a type of tube worm found in the shallow sublittoral zone of the eastern Atlantic Ocean. ''Bispira volutacornis'' has a parchment-like tube with a mucoid outer layer which is often coated with mud or silt. The tube is usually concealed in a crevice and the worm can retract into the tube when disturbed. Description ''Bispira volutacornis'' tends to grow in colonial groups. Each individual worm has a double-headed crown formed from several whorls of up to 200 feathery plumes. There are one or more pairs of composite eyes on the outer side of the crown. The worm secretes a soft, parchment-like tube, about in diameter from which it protrudes and into which it can retract when disturbed. The outside of the tube is often covered with mud or silt. When the crown is retracted, the top of the tube becomes pinched together, forming a figure-of-eight shape. The worm's body is greenish or brow ...
