Freshwater Mussels of the Upper Mississippi River System |
|
Nearly 300 species of mussels inhabit freshwater rivers and lakes in North America. This is the richest diversity of mussels found in the world. Freshwater mussels are sedentary, long-lived (some live over 100 years) mollusks that live in sediments and filter water to feed. Because they are filter-feeders, mussels are excellent indicators of the health of aquatic ecosystems. In addition, mussels are a vital link in the food chain because they are a major food item for wildlife such as raccoon, muskrat, and otter. Their lustrous pearl-like interiors have made them valuable in the cultured pearl and jewelry industry. |
