Freshwater clams are small, bivalve mollusks that live in rivers, lakes, and ponds. They have two hinged shells that protect their soft bodies inside. These clams play an important role in their ecosystems by filtering water, which helps keep it clean and clear. They feed on tiny particles like algae and organic matter, making them essential for maintaining water quality. These clams can be found in various shapes and sizes, depending on their species. Some common types include the Eastern Elliptio and the Asian Clam. Freshwater clams are also a food source for many animals, including fish and birds, contributing to the biodiversity of their habitats.
