Clavatula Luctuosa
''Clavatula'' is a genus of sea snails, marine gastropod mollusks in the family Clavatulidae. Description In this genus, the shell is fusiform, with a well-produced spire. The whorls are coronated with tubercles or short spines at the suture;. The aperture is oval. The columellar lip is smooth, arcuate, and callous behind. The outer lip is thin and arcuated, with the anal sinus situated below the sutural coronal. The operculum is semioval with its nucleus about the middle, on the inner side. The foot is large, short and obtuse behind. The eyes are placed externally near the extremity of the tentacles. The radula contains a small unicuspid central tooth with single sharp laterals (formula :1-1-1). The species mostly inhabits the west coast of Africa. Species Species within the genus ''Clavatula'' include: * ''Clavatula ahuiri'' Cossignani & Ardovini, 2014 * †''Clavatula aralica'' (Luković, 1924) (an extinct species from the Eocene in western Kazakhstan (Tshegan Fo ...

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 ...
