Genus Anodonta is a group of freshwater mussels commonly found in temperate regions of Europe and North America. These mussels are also referred to as pond mussels, swan mussels, and duck mussels due to their habitat and nature of feeding. They are filter feeders and play a vital role in maintaining the ecological balance of freshwater systems. Other synonyms for Genus Anodonta include Unio, Margaritifera, Gonidea, and Pyganodon. While their size and appearance vary among the species, most of them have a smooth and round shell with a slightly curved hinge line. These mussels are also an important food source for various aquatic animals, including otters and muskrats, and were used historically by humans for food and ornamentation.
