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 ...

Pyrgiscus Crenatus
''Pyrgiscus crenatus'' is a species of sea snail, a marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies.Gofas, S. (2015). Pyrgiscus crenatus (Brown, 1827).

In the former case it cannot be determined to which of the two species corresponds the earliest name ''Pyramis crenatus'' Brow ...
