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 ...

Nacella Concinna
''Nacella concinna'' is a species of sea snail, a true limpet, a marine gastropod mollusk in the family (biology), family Nacellidae, one of the families of true limpets.Bouchet, P. (2014). Nacella polaris (Hombron & Jacquinot, 1841). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=713922 on 2015-01-26 Description The shell of ''Nacella concinna'' grows to about long with deep water specimens being rather smaller. It is an elongated ovate, moderately elevated cone with a low apex somewhat towards the anterior margin and angled in that direction. There are about 30 faint radial ribs and a series of fine concentric lines that indicate the annual growth rings. The exterior of the shell is varying shades of pale brown and grey and the interior is dark purplish-brown in deep water specimens but creamy-brown in those from shallow water. The mantle has a fringe of short tentacles. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Iothia Emarginuloides
''Iothia emarginuloides'' is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Lepetidae, one of the families of true limpets. This species was previously known as ''Iothia coppingeri''. Taxonomy The type specimens of ''I. emarginuloides'' (Philippi, 1868) and ''I. coppingeri'' (E.A. Smith, 1881) are very similar in morphology, and were collected only apart; as long ago as 1908 this led to the recognition that they were probably the same species. Despite this, they continued to be treated as two separate species until 2011, when Nakano et al. researched the genus and brought them into synonymy. ''I. emarginuloides'' was described before ''I. coppingeri'', so by the rules of zoological nomenclature, the earlier name took priority. Description ''I. emarginuloides'' is a small, broadly ovate, cap-shaped limpet, with a length of about and width of . The apex of the shell is towards the anterior end, and is rather acute, but does not curl over. The she ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sea Snail
Sea snails are slow-moving marine (ocean), marine gastropod Mollusca, molluscs, usually with visible external shells, such as whelk or abalone. They share the Taxonomic classification, taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible Gastropod shell, shell. Definition Determining whether some gastropods should be called sea snails is not always easy. Some species that live in brackish water (such as certain Neritidae, neritids) can be listed as either freshwater snails or marine snails, and some species that live at or just above the high tide level (for example, species in the genus ''Truncatella (gastropod), Truncatella'') are sometimes considered to be sea snails and sometimes listed as land snails. Anatomy Sea snails are a very large and diverse group of animals. Most snails that live in salt water respire using a gill or gills; a few species, though, have a lung, are intertidal, and are active only at low tide w ...
