They are characterized by their small, often cylindrical, ovate, or elongate shells.

They are generally tiny, ranging from a few millimeters to about a centimeter in length.

The aperture often has denticles (teeth) or lamellae, which may play roles in predator deterrence or structural support.

The margin of the aperture often features a well-defined peristome, sometimes thickened or reflected.

They can be found in dry and arid regions to temperate forests and even tropical zones.
