Gastrocopta Tavennerensis
''Gastrocopta'' is a genus of minute air-breathing land snails, terrestrial molluscs, terrestrial pulmonate gastropod mollusks or micromollusks in the family Gastrocoptidae.MolluscaBase (2018). Gastrocopta Wollaston, 1878. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=818270 on 2018-10-14 ''Gastrocopta'' is the type genus of the subfamily Gastrocoptinae. The height of the gastropod shell, shell is about 2 mm. Distribution The Recent distribution of ''Gastrocopta'' includes North America, eastern Asia, central Asia and South America (List of non-marine molluscs of Brazil, Brazil and List of non-marine molluscs of Venezuela, Venezuela). In Europe, the genus ''Gastrocopta'' has been Local extinction, extirpated; its fossils there are known mainly from the Neogene, but its fossil range in Europe is from the Oligocene to the Lower Pleistocene.

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 ...
