Vitrina

Vitrina is a genus of land snails that are characterized by their very thin, translucent spiral shells with large apertures. These snails are sometimes referred to as "glass snails" because their shells resemble those of slugs.12

Snails, as gastropods, exhibit a wide diversity in size and shell shape, with some species being less than a millimeter in diameter and others growing to over two feet long. The Vitrina genus belongs to the subclass Pulmonata, which typically lacks an operculum (a protective disk that seals the shell aperture) and has complex body structures.3
