Georissa

Georissa is a genus of minute land snails belonging to the family Hydrocenidae. These snails are characterized by their small size, typically measuring only a few millimeters in shell diameter. They are found in various tropical and subtropical regions, often inhabiting moist environments such as leaf litter, damp rocks, and forest floors.

Georissa shells are typically globose or turbiniform in shape and often exhibit intricate sculptural details, which are used for species identification. Their operculum, a plate-like structure that seals the shell aperture, is calcareous.

The diet of Georissa snails is believed to consist primarily of detritus, algae, and other organic matter found in their habitat. They play a role in decomposition and nutrient cycling within their ecosystems.

Due to their small size and cryptic habits, Georissa snails are often overlooked in ecological surveys, and the taxonomy and distribution of many species remain poorly understood. Some species may be highly localized and potentially threatened by habitat loss.
