Abida (genus)
''Abida'' is a genus of small air-breathing land snails, terrestrial molluscs, terrestrial gastropod mollusks in the family Chondrinidae. Distribution This is a European genus. It consists of about 10 species, most of which are restricted to the Pyrenees and Cantabrian mountains in France and Spain. Only ''Abida secale'' and ''Abida polyodon'' occur outside this area. Species The species in this genus include:Kokshoorn, B. and Gittenberger, E. 2010. Chondrinidae taxonomy revisited: New synonymies, new taxa, and a checklist of species and subspecies (Mollusca: Gastropoda: Pulmonata). Zootaxa 2539: 1-62. Habitat The species in this genus all are restricted to areas with calcareous rocks, i.e. limestone areas.

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 ...
