Description

All the species of snails in the family of door snails are left-handed, which is an uncommon feature in gastropods in general. These snails have shells which are extremely high-spired, with numerous whorls.

Clausilia dubia is a relatively large species for this family, reaching 16 mm in height.

The weight of the adult live snail is about 123 mg.[4]
