👉 Peristeropodans is a genus of crustaceans from the family Peristeridae, which are commonly found in freshwater habitats. These animals belong to the order Crustacea and are characterized by their hard shells made of calcium carbonate, which gives them an insulating effect. The peristeropods have a wide range of life styles, including sessile (living in water), attached to aquatic plants or other organisms, or invertebrates that live on the surface of water bodies.
