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 ...

''Pyrgulina arfica'' is a species of sea snail, a marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies.Rosenberg, G. (2011). ''Pyrgulina arfica'' (Bartsch, 1915). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=588500 on 2012-01-12 Description The bluish-white, rather solid shell has an elongate-ovate shape. Its length measures 4 mm. The whorls of the protoconch are decollated. The five whorls of the teleoconch are well rounded, and strongly shouldered at the summit. They are marked by stout, well-rounded, somewhat sinuous, decidedly protractive, axial ribs, which are about as wide as the spaces that separate them. Of these ribs, 14 occur upon the first, 16 upon the second, 18 upon the third, and 22 upon the penultimate turn. These ribs render the summit of the whorls decidedly crenulated. In addition to the ribs the intercostal spaces are marked between the sutures by exceedingly fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
