Albinaria Eburnea
''Albinaria'' is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Clausiliidae, called the door snails. Ecology and Life Cycle These species of snails live on limestone rocks, where they feed on algae and lichen. They are known to be active during the rainy seasons, that is, in Mediterranean lowlands, from November to April. Eggs are laid shortly after the beginning of the wet season. It takes two to three wet seasons for development from a juvenile to a fully grown shell . During the intermittent dry seasons, both young and adult snails, aestivate ("the warm weather equivalent of hibernation") on the rocks or in crevices inside the rocks. For aestivation, aggregates are often formed, sometimes reaching sizes of many hundreds of individuals. During the last dry season prior to sexual maturation, the subadult snail (the shell of which is already fully developed, albeit thinner than that of an adult) increases the size of its genital org ...

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 ...

Albinaria Ariadne
''Albinaria ariadne'' is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Clausiliidae, the door snails. The species is endemic to Crete. It has been stated that further research is necessary whether ''Albinaria ariadne'' is an independent species. Based on shell characters it seems closely related to '' Albinaria idaea'', except that ''Albinaria ariadne'' has a weak basalis.Welter-Schultes, F. 2010.

Albinaria Caerulea
''Albinaria caerulea'' is a species of air-breathing rock-dwelling clausiliidae land snail, a terrestrial pulmonate gastropod mollusk in the family Clausiliidae, the door snails. Habitat ''Albinaria caerulea'' lives, like most ''Albinaria'' species, on limestone substrates in semi-arid habitats, and aestivates on limestone rock-surfaces covered by lichens, algae and mosses. Description This species has a medium-sized shell which is smooth and white, and measures up to 16 mm tall. ''Albinaria caerulea'' usually occurs in large numbers, however numbers can fall sharply if there are predators around such as birds. The estimated life of a snail of this species is around 7 years. Distribution This species occurs in: * Greece Greece, officially the Hellenic Republic, is a country in Southeast Europe. Located on the southern tip of the Balkan peninsula, it shares land borders with Albania to the northwest, North Macedonia and Bulgaria to the north, and Turkey to th ... R ...
