What are mussels? Freshwater bivalves, commonly known as mussels, belong to the order Unionoida and are found on every continent except Antarctica. Bivalve means having two sides or shells. They inhabit lakes, ponds, creeks, and rivers. Mussels’ main food source is algae. They obtain algae by filtering or straining the water; Along with filtering out food they also filter out heavy metals and dirt particles in the water. Nonedible particles are deposited into the ground rendering clearer water.
