Komprenidae
Komprenidae is a family of small, freshwater snails, aquatic gastropod mollusks in the superfamily Lymnaeoidea. The family was first described by the German malacologist Friedrich von Martens in 1860. Komprenidae are characterized by their small size, typically less than 10 millimeters in length, and their smooth, rounded shells. The family is found in freshwater habitats around the world, including Europe, Asia, Africa, and the Americas. Komprenidae are herbivorous, feeding on algae and other plant material. They are often found in slow-moving or still waters, such as ponds, lakes, and marshes. The family includes several genera, with the most well-known being Komprena, which is found in Europe and Asia. Komprenidae are of interest to scientists due to their unique shell morphology and their role in freshwater ecosystems. However, they are not considered to be of significant economic importance.
