Crassispira Aesopus
''Crassispira'' is a genus of small predatory sea snails with narrow, high-spired shells, marine gastropod mollusks in the family Pseudomelatomidae.MolluscaBase (2018). Crassispira Swainson, 1840. Accessed through: World Register of Marine Species at: http://marinespecies.org/aphia.php?p=taxdetails&id=224467 on 2018-04-21 Taxonomy The small blackish Drillias so common in Panamic waters, of which ''Pleurotoma bottae'' Valenciennes is the type, were brought under the name of ''Crassispira'' Swainson, 1840 by W.H. Dall in 1918. Description Most species in this genus have a tall spire and a truncated anterior canal. The ribs are overridden by spirals, forming beads or nodules. Under the subsutural keel is the sinus area rather smooth. The small shell is subclavate and tuberculated. The spire is thick and, lengthened. The outer lip shows a slight sinus above and is thickened internally at the top and the bottom. The top of the inner lip has a thick pad. The basal channel is slight ...

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 ...
