clublike door snail

Clausilia pumila, the clublike door snail, is a land snail in the family Clausiliidae, a group readily recognized by their sinistral (left-handed) coiling and elongated, spindle-shaped shells. C. pumila has a smooth, glossy shell approximately 12–18 mm in height, tapering to a slender apex, with fine growth lines and a distinctive clausilium—a small, spring-loaded plate inside the aperture that closes when the snail retreats. This clausilium gives the family its common name of door snails. The species is distributed across central and eastern Europe, from Germany and the Czech Republic eastward through Poland and neighboring countries, inhabiting moist deciduous forests, especially beech and mixed woodland with rich ground flora. It is typically found on limestone or calcareous substrates, living under bark, in leaf litter, on mossy rocks and rotting logs, and occasionally on living tree bark. Like other clausiliids, it is a microphytophage, rasping algae, fungi, and decaying plant material from surfaces. C. pumila is classified as Least Concern, being locally common across its range where suitable humid forest habitats persist.

Green Sea Turtle

The green sea turtle is one of the largest sea turtles. They are named for the green color of their cartilage and fat, not their shells.
