Naiadopex

Naiadopex is a genus of freshwater snails belonging to the family Viviparidae. These aquatic gastropod mollusks are characterized by their coiled shells, operculum for shell closure, and their habit of living submerged in freshwater environments such as rivers, lakes, and ponds. The shells of Naiadopex species typically exhibit a trochiform or ovate shape, with varying degrees of spire height and ornamentation depending on the specific species and its habitat. They are filter feeders, using their ctenidia to strain organic matter from the water.

The distribution of Naiadopex species is primarily concentrated in Southeast Asia, with some species found in other parts of the Indo-Pacific region. They are often found in slow-moving or stagnant waters with abundant aquatic vegetation. Reproduction in Naiadopex is ovoviviparous, meaning that the eggs hatch internally, and live young are released. This reproductive strategy allows for a higher survival rate of offspring compared to species that lay eggs externally.

Ecologically, Naiadopex plays a role in the freshwater ecosystem by contributing to water clarity through filter feeding and serving as a food source for various aquatic predators. Conservation status varies among species, with some facing threats from habitat degradation, pollution, and overcollection. Research into Naiadopex often focuses on their taxonomy, ecological roles, and the impact of environmental changes on their populations.
