Calliostomatidae - Calliostoma Conulus
Calliostomatidae is a family of sea snails within the superfamily Trochoidea and the clade Vetigastropoda.Gofas, S. (2013). Calliostomatidae. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=382180 on 2013-07-08 Description The Calliostomatidae are unusually diverse. They are characterized by a stepped spire and a pointy aperture. They may possess or lack an umbilicus. The collumella is sometimes thicker, partially covering the aperture. The spiral whorls can differ between narrow and robust. They inhabit a wide range of ocean habitats, from the intertidal zone to mid- bathyal depths. Taxonomy This taxon was long considered to be a subfamily of the Trochidae. 2005 taxonomy This family consists of two following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005): * subfamily Calliostomatinae Thiele 1924 (1847) ** tribe Calliostomatini Thiele 1924 (1847) - synonym: Ziziphinin ...

Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...

Calliostoma
''Calliostoma'' is a genus of small to medium-sized sea snails with gills and an operculum, marine gastropod molluscs within the family Calliostomatidae, the Calliostoma top snails. Previously this genus was placed within the family Trochidae. ''Calliostoma'' is the type genus of the family Calliostomatidae. Taxonomy The name of this genus is derived from the Greek words ''kallos'' (beautiful) and ''stoma'' (mouth), referring to the pearly aperture of the shell. The genus ''Calliostoma'' is known in fossil records from the Upper Cretaceous onwards. As of 2022, ''Calliostoma'' is treated as a very broad genus of about 300 accepted species. While current information is too fragmentary to assign all species in a revised genus, it is expected to be broken up and (some) subgenera will be elevated to the status of genus. A complete listing can be found at the list of ''Calliostoma'' species. Description The rather thin, acute, coeloconoid (=approaching conical shape but with c ...

Molecular Phylogeny
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Calliostoma Unicum
''Calliostoma unicum'', common name Dall's unicum top shell, is a species of sea snail, a marine gastropod mollusk in the family Calliostomatidae. Some authors place this taxon in the subgenus ''Calliostoma (Tristichotrochus)'' Description The height of the shell varies between 13 mm and 23 mm. The solid, conical shell is imperforate. It has seven, inflated globose whorls with a rounded periphery and a closed umbilicus. The whorls show a more or less obvious angle or carina in the middle of the upper surface. The body whorl is subangular or rounded at the periphery and convex beneath. The surface texture consists of numerous, unequal spiral striations which are beaded on the early whorls. These striations are slightly crenulated by regular incremental lines. These striations number about 9 on the penultimate whorl, 12–14 on the base. The low spire is rather short. The acute apex is red or purplish. The oblique, rhomboidal aperture is white and nacreous. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
