Planorbidae is a family of freshwater snails known for their distinctive coiled shells. These snails are commonly found in ponds, lakes, and slow-moving rivers around the world. They play an important role in aquatic ecosystems by helping to break down organic matter and serving as a food source for various predators. Members of the Planorbidae family are characterized by their flattened, spiral-shaped shells, which can vary in color and size. They are hermaphroditic, meaning each individual has both male and female reproductive organs, allowing them to reproduce efficiently in their habitats.
