Galba Meridensis
''Galba meridensis'' is a species of air-breathing freshwater snail, an aquatic animal, aquatic pulmonate gastropod mollusc in the family Lymnaeidae, the pond snails. MolluscaBase eds. (2021). MolluscaBase. Galba meridensis (Bargues, Artigas, Khoubbane & Mas-Coma, 2011). Accessed through: World Register of Marine Species at: http://marinespecies.org/aphia.php?p=taxdetails&id=1062552 on 2021-05-20 This species appears to be endemic to very high altitudes. This species belong to the ''Galba (gastropod), Galba''/''Fossaria'' group, therefore this species should be named ''Galba meridensis''. cf.Bargues M.

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 ...
