Lustá

Lustá is a genus of small, operculate snails belonging to the family Clausiliidae. These land snails are characterized by their elongated, sinistral (left-coiled) shells. The shell aperture is typically narrow and possesses a distinct, movable plate called the clausilium. This clausilium is a significant feature of the Clausiliidae family, used to seal the shell aperture.

Species within the genus Lustá are primarily found in parts of Southern Europe, particularly in mountainous and forested regions. They inhabit damp environments, often found on rocks, bark, or among leaf litter. Their diet generally consists of algae, fungi, and decaying plant matter.

The reproductive biology of Lustá snails is similar to other clausiliids, often involving internal fertilization and the laying of eggs. The exact number of species and their distribution can vary depending on taxonomic classifications and ongoing research. Studying Lustá contributes to our understanding of gastropod diversity and the evolutionary adaptations of land snails in specific ecological niches. Their relatively small size and specific habitat requirements can make them indicators of environmental health in their native regions.
