Zenepos Totolirata
''Zenepos totolirata'' is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae. Description The length of the shell attains 3.4 mm, its diameter is 1.4 mm. (Original description) The minute shell is narrowly fusiform, thin, semitransparent and spirally lirate. Sculpture : The protoconch is microscopically finely spirally striate, the succeeding whorls have 3 and the body whorl has 10 to 12 equidistant fine spiral lirae. The interstices are smooth and slightly broader than the threads. The colour of the shell is white. The spire is narrowly conical, measuring about 1½ times the height of the aperture. The protoconch consists of 1½ convex whorls, the nucleus is narrowly rounded and oblique. There are 4 to 5 subsequent whorls, regularly increasing, lightly convex and somewhat flattened below the suture. The base of the shell is slightly contracted. The suture is not much impressed. The aperture is high and narrow, angled above, with a very shor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raphitomidae
Raphitomidae is a family of small to medium-sized sea snails, marine gastropod mollusks in the superfamily Conoidea.Bouchet P. & Rocroi J.-P. (Ed.) (2005). "Classification and nomenclator of gastropod families". ''Malacologia'' 47(1-2). . 397 pp. Bouchet, Kantor ''et al''. elevated in 2011 the subfamily Raphitominae (which at that point had been placed in the family Conidae) to the rank of family. This was based on a cladistical analysis of shell morphology, radular characteristics, anatomical characters, and a dataset of molecular sequences of three gene fragments. The family was found to be monophyletic. Description The Raphitomidae is the largest, most diverse and most variable taxon in the Conoidea, with the greatest number of species and the largest ecological range (from the tropics to the pole) and largest vertical range (intertidal to hadal depths). The shells of species in the Raphitomidae are very variable in shape (buccinoid to ovate, elongate-fusiform, or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nepotilla Mimica
''Nepotilla mimica'' is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae. ;Variety: ''Nepotilla mimica fusca'' (Sowerby III, 1896) : a dark brown variety. Description The length of the shell attains 7 mm, its diameter 2.5 mm. This little, white, turreted shell bears rather a curious resemblance to the ''Daphnella (Teres)'' (synonym of ''Teretia teres'' (Reeve, 1844) ). The spire is elongate and very sharp. The shell contains 6 convex, rounded whorls. These are slightly concave at the top. The sculpture consists of conspicuous lirae, alternated with smaller lirae, sculptedc lengthwise by minute, oblique lamellae. The body whorl is rather short, contracted at the base and slightly rostrate. The columella is slightly twisted. The aperture is ovate. The outer lip is sharp and arcuate. The sinus is deep and not very wide. The author has only seen three specimens, the type here described being the largest. The two smaller ones are shorter in propor ...

Nepotilla Minuta
''Nepotilla minuta'', common name the minute turrid, is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae. ''Daphnella minuta'' Verco, 1909 is a synonym of ''Nepotilla mimica'' (Sowerby III, 1896), according to Hedley (1922). Description The length of the shell attains 6 mm. (Original description) The minute shell is fusiform, turreted, elongate and thin. It is saturated with a reddish chestnut. It contains 6 convex whorls, including the protoconch. They are spirally many keeled and between the keels thickly and slenderly longitudinally lirate. The protoconch consists of two subinflated whorls which are spirally and equally striate. The aperture is shorter than the spire, elongately ovate. The outer lip is thin and sinuous. The inner lip is inconspicuous. [...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] |
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 ...
