Dwarf Wedge Mussel (Alasmidonta heterodon): Endangered
This brown or yellowish-brown freshwater mussel is about 1.5 inches in length. Their life span is about 10 years. They feed on algae and other suspended particulates. These mussels live in running water of small brooks to large rivers, mostly on the East Coast. Water pollution, including sediments and chemicals from agriculture and other development projects such as golf courses, have been implicated in the mussel's decline.
