Chitonotus
Chitonotus is a genus of marine gastropods belonging to the family Clausiliidae. These small, air-breathing land snails are known for their distinctive shell structure and are found primarily in the Mediterranean region. While commonly referred to as “clausiliid snails,” the genus Chitonotus stands out due to its unique shell morphology and geographical distribution.
Characteristics
Members of the genus Chitonotus are characterized by their small, elongated, and often cylindrical shells. These shells are typically brown or gray in color and possess a distinctive feature known as a "clausilium," a specialized structure that acts as a door to seal the aperture of the shell when the snail retracts inside. The clausilium plays a crucial role in regulating moisture and preventing desiccation, particularly in dry environments.
Environment
Chitonotus snails are primarily terrestrial and prefer habitats characterized by moderate to high humidity. They can be found in forests, woodlands, and rocky areas where they often dwell under rocks, logs, or leaf litter. Their distribution is primarily restricted to the Mediterranean region, with a focus on the Iberian Peninsula, Italy, and the Balkans.
