Buccinoidea (unassigned)
Buccinoidea is a Taxonomy (biology), taxonomic Taxonomic rank, superfamily of very small to large predatory sea snails, marine (ocean), marine gastropod mollusks. This superfamily is in the clade Neogastropoda according to the taxonomy of the Gastropoda (Bouchet & Rocroi, 2005). It had been placed within the infraorder Neogastropoda according to the taxonomy of the Gastropoda (Ponder & Lindberg, 1997). Families These families are within Buccinoidea in the taxonomy of the Gastropoda by Bouchet & Rocroi (2005): * Austrosiphonidae Cotton & Godfrey, 1938 * Belomitridae Kantor, Puillandre, Rivasseau & Bouchet, 2012 * Buccinanopsidae Galindo, Puillandre, Lozouet & Bouchet, 2016 * Buccinidae Rafinesque, 1815 * Busyconidae Wade, 1917 (1867) * Chauvetiidae Kantor, Fedosov, Kosyan, Puillandre, Sorokin, Kano, R. Clark & Bouchet, 2022 * Colubrariidae Dall, 1904 * Columbellidae Swainson, 1840 * Cominellidae Gray, 1857 * Dolicholatiridae Kantor, Fedosov, Kosyan, Puillandre, Sorokin, Kano, R. C ...

Gastropod Shell
The gastropod shell is part of the body of many gastropods, including snails, 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, ostracum, is typically made of calcium carbonate (CaCO3) precipitated into an organic matrix ...
