Truncatulidae

Truncatulidae is a family of freshwater snails, belonging to the subclass Caenogastropoda. These snails are characterized by their shells, which are typically conical or turbinate in shape. The aperture of the shell is often ovate and may possess a parietal callus. Truncatulidae are found in various freshwater habitats, including rivers, lakes, and streams, primarily in Asia.

Members of this family are herbivores or detritivores, feeding on algae, aquatic plants, and decaying organic matter. Their reproductive strategy generally involves the laying of eggs, although some species may exhibit ovoviviparity. The family Truncatulidae is relatively small, with a limited number of recognized genera and species. Further research is ongoing to fully understand the taxonomy and ecological roles of this group.
