Cypraeoidea
Cypraeoidea, the cowries and cowry allies, is a superfamily of sea snails, marine gastropods included in the clade Littorinimorpha. This superfamily had been called Cypraeacea and was named by Rafinesque in 1815.MolluscaBase (2018). Cypraeoidea Rafinesque, 1815. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=14774 on 2018-07-18 Shell description This superfamily of sea snails have adult shells which do not look like typical gastropod shells because the spire of the shell is not visible in adults, instead the shells are: often quite rounded in shape, varying from globular to elongate, and with a long, very narrow, aperture which is sometimes toothed. The snails in these families have no operculum. The shells of almost every species in this superfamily are very smooth and shiny, and this is because in the living animal, the shell is nearly always fully covered with the mantle.

Eocypraeidae
Eocypraeidae is a small family of large sea snails, marine gastropod molluscs in the superfamily Cypraeoidea, the cowries and cowry allies. MolluscaBase eds. (2022). MolluscaBase. Eocypraeidae F. A. Schilder, 1924. Accessed through: World Register of Marine Species at: https://www.marinespecies.org/aphia.php?p=taxdetails&id=878564 on 2022-06-19 The family Eocypraeidae consists mainly of fossil species, except for two species: '' Sphaerocypraea incomparabilis'' Briano, 1993 (regarded as valid) and an as yet undescribed species found in the southern Atlantic. In 1963, a fresh shell of what was subsequently named ''Sphaerocypraea incomparabilis'' was dredged up by a Soviet trawler in the Gulf of Aden. There are currently (2009) only six known specimens of this shell in various collections. Taxonomy The taxonomy of Eocypraeidae is not fully understood and has undergone several modifications. 2005 taxonomy According to the taxonomy of Bouchet & Rocroi (2005) this family be ...

Pediculariinae
Pediculariinae is a subfamily (biology), subfamily of small to large predatory or parasitic sea snails, marine (ocean), marine gastropod molluscs in the family Ovulidae and the superfamily Cypraeoidea, the cowries and the cowry allies. As of 2009, it comprises 48 described species of which 20 are regarded as valid by most scientists. Taxonomy Simone (2004)Simone L. R. L. (2004). "Morphology and Phylogeny of the Cypraeoidea (Mollusca, Caenogastropoda)". ''Papel Virtual Editoria'' (Rio de Janeiro): 185 pp. placed some genera in the family Pediculariidae which were previously in the family Ovulidae. Comparison of the Mollusc shell, shell, radula and morphology (biology), morphology suggested a closer phylogenetic relationship to the Pediculariidae than to the Lamellariidae, the Eratoidae/Triviidae, or the Ovulidae. However, both the validity of the family Pediculariidae, and its proper position within the superfamily Cypraeoidea, remain controversial. As of 2019, the World Register ...

Ovulidae
Ovulidae, common names the ovulids, cowry allies or false cowries, is a family of small to large predatory or parasitic sea snails, marine gastropod molluscs in the superfamily Cypraeoidea, the cowries and the cowry allies. MolluscaBase eds. (2020). MolluscaBase. Ovulidae J. Fleming, 1822. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=1747 on 2020-05-25 Distribution The ovulids are a widespread family, occurring mostly in tropical and subtropical waters, with most species in the Indo-West Pacific region. But a few species live in temperate waters. Habitat Ovulids are carnivorous molluscs that feed on polyps and tissues of Anthozoa (as do the genera ''Cyphoma'' and ''Pseudocyphoma''). They live on, and eat, soft corals and sea fans, and they are usually regarded as ectoparasites of these sessile colonial organisms, to which they are anchored by a long and narrow foot.

Cypraeidae
Cypraeidae, commonly named the cowries ( cowry), is a taxonomic family of small to large sea snails. These are marine gastropod mollusks in the superfamily Cypraeoidea, the cowries and cowry allies. Shell description Cypraeidae have adult shells which are very rounded, almost like an egg; they do not look like a typical gastropod shell. In virtually all of the species in the family Cypraeidae, the shells are extremely smooth and shiny. This is because in the living animal, the shell is nearly always fully covered with the mantle. Typically, no spire is visible in the fully adult shell, and there is a long, narrow, aperture which is lined with "teeth". Juvenile cowry shells are not at all similar to adult cowry shells. The juvenile shells of cowries perhaps more closely resemble the shells of some "bubble snails" in the order Cephalaspidea. Also the shells of juvenile cowries seldom exhibit the same color patterns as the adult shells do, and thus can be hard to identify to spe ...

Taxonomy Of The Gastropoda (Bouchet & Rocroi, 2005)
The taxonomy of the Gastropoda as it was revised in 2005 by Philippe Bouchet and Jean-Pierre Rocroi is a system for the scientific classification of gastropod mollusks. (Gastropods are a taxonomic class of animals which consists of snails and slugs of every kind, from the land, from freshwater, and from saltwater.) The paper setting out this taxonomy was published in the journal ''Malacologia''. The system encompasses both living and extinct groups, as well as some fossils whose classification as gastropods is uncertain. The Bouchet & Rocroi system was the first complete gastropod taxonomy that primarily employed the concept of clades, and was derived from research on molecular phylogenetics; in this context a clade is a "natural grouping" of organisms based upon a statistical cluster analysis. In contrast, most of the previous overall taxonomic schemes for gastropods relied on morphological features to classify these animals, and used taxon ranks such as order, superorder ...

Spire (mollusc)
A spire is a part of the coiled shell of molluscs. The spire consists of all of the whorls except for the body whorl. Each spire whorl represents a rotation of 360°. A spire is part of the shell of a snail, a gastropod mollusc, a gastropod shell, and also the whorls of the shell in ammonites, which are fossil shelled cephalopods. In textbook illustrations of gastropod shells, the tradition (with a few exceptions) is to show most shells with the spire uppermost on the page. The spire, when it is not damaged or eroded, includes the protoconch (also called the nuclear whorls or the larval shell), and most of the subsequent teleoconch whorls (also called the postnuclear whorls), which gradually increase in area as they are formed. Thus the spire in most gastropods is pointed, the tip being known as the "apex". The word "spire" is used, in an analogy to a church spire or rock spire, a high, thin, pinnacle. The "spire angle" is the angle, as seen from the apex, at which a spire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
