Burnupena Papyracea
''Burnupena papyracea'', common name the papery burnupena, is a species of sea snail, a marine gastropod mollusk in the family Buccinidae, the true whelks. Description The length of the shell attains 60 mm, The oblong, conical shell is rather thin. It is of a reddish-brown color, covered transversely with striae and ridges, with some slightly apparent longitudinal striae. The transverse ridges are raised and very prominent. The spire is elongated and contains seven whorls. These are convex and depressed at their upper part. The body whorl is longer than all the others together. The aperture is elongated, ovate, of a reddish yellow, and slightly emarginated at its base. The outer lip is thin, forming at its upper and internal part a sort of small canal at its union with the left lip.

Burnupena Catarrhacta
''Burnupena catarrhacta'', common name the flame-patterned burnupena, is a species of sea snail, a marine gastropod mollusk in the family Buccinidae, the true whelks. Description The length of the shell varies between 25 mm and 50 mm. The ovate shell is elongated and subturrited. The external surface is of a bluish ash color, marked with very fine, close striae. It is also ornamented with longitudinal undulated bands or flames, formed by lines more or less approximated. The epidermis is greenish. The slightly pointed spire is composed of six whorls, which are slightly convex, and united by a pretty delicate regular suture. The aperture In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical system determine the cone angle of a bundle of rays that come to a focus in the image plane.

Burnupena Pubescens
''Burnupena pubescens'' is a species of sea snail, a marine gastropod mollusk in the family Buccinidae, the true whelks. Description The size of an adult shell varies between 40 mm and 50 mm. Very similar to ''B. papyracea''. Also often covered with the encrusting bryozoan ''Alcyonidium nodosum'' and differs mainly in being smaller and having fine longitudinal ridges which cross the spirals to produce a slightly checkered effect, generally not visible under the bryozoan.Branch, G.M., Branch, M.L, Griffiths, C.L. and Beckley, L.E. (2010). ''Two Oceans: a guide to the marine life of southern Africa'' Struik Nature, Cape Town. The ovate shell is elongated and subturreted. It is generally of a clear fawn color, marked with numerous spots of a deep chestnut or reddish color, oblong or quadrangular, alternating with other similar spots of a dull white. The first, oftentimes, form longitudinal bands. The pointed spire is conical and, formed of six slightly convex whorls, t ...

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 ...
