Oscilla (gastropod)
''Oscilla'' is a genus of very small sea snails, minute marine gastropod mollusks or micromollusks. This genus is currently placed in the subfamily Chrysallidinae of the family Pyramidellidae.Rosenberg, G.; Gofas, S. (2011). Oscilla A. Adams, 1861. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=138415 on 6 July 2012 These marine gastropods have shells with intorted protoconchs. Life history Little is known about the biology of the members of this genus. As is true of most members of the Pyramidellidae ''sensu lato'', they are likely to be ectoparasites. '' Oscilla jocosa'' may possibly be a parasite on ''Trochus erithreus'' (Mienis 2003). Species of ''Oscilla'' The following species are mentioned in WoRMS: * '' Oscilla annulata'' (A. Adams in H. & A. Adams, 1853) * '' Oscilla appeliusi'' (Hornung & Mermod, 1925) * '' Oscilla aqabaensis'' Peñas, Rolán & Sabelli, 2020 * '' Oscilla aquilonia'' Pimenta, Santos ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), 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 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 ...
