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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nacella Concinna
''Nacella concinna'' is a species of sea snail, a true limpet, a marine gastropod mollusk in the 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] |
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 ...

Sea Snail
Sea snail is a common name for slow-moving marine gastropod molluscs, usually with visible external shells, such as whelk or abalone. They share the taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible 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 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'') are sometimes considered to be sea snails and sometimes listed as land snails. Anatomy Sea snails are a very large group of animals and a very diverse one. 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 when they can move around in the air. These air-breathing species includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
True Limpet
The Patellogastropoda, common name true limpets and historically called the Docoglossa, are members of a major phylogenetic group of marine gastropods, treated by experts either as a clade or as a taxonomic order. The clade Patellogastropoda is deemed monophyletic based on phylogenetic analysis. Taxonomy Patellogastropoda was proposed by David R. Lindberg, 1986, as an order, and was later included in the subclass Eogastropoda Ponder & Lindberg, 1996. 2005 taxonomy Bouchet & Rocroi, 2005 designated Patellogastropoda, true limpets, as a clade, rather than as a taxon, but within included superfamilies and families as listed below. Families that are exclusively fossil are indicated with a dagger †: *Superfamily Patelloidea **Family Patellidae *Superfamily Nacelloidea **Family Nacellidae *Superfamily Lottioidea **Family Lottiidae **Family Acmaeidae Forbes, 1850 ***subfamily Acmaeinae Forbes, 1850 ***subfamily Pectinodontinae Pilsbry, 1891 ***subfamily Rhodopetalinae Li ...

Gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Mollusk
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
