👉 Heterophryidae are a family of freshwater snails, which include several genera with diverse species ranging from small aquatic creatures to large crustaceans. They are characterized by their elongated heads and short, curved bodies that are covered in hard, scaly exoskeletons. Heterophryids have a wide range of ecological roles in freshwater systems, including feeding on planktonic organisms, deterring predators, or as food for other species.
