Surveying the extant population of Dwarf wedgemussel at Ashuelot River in Surry, New Hampshire, NH. The dwarf wedgemussel is a small bivalve, rarely exceeding 45 mm in length. Clean young shells are usually greenish-brown with green rays. As the animal ages, the shell color becomes obscured by diatoms or mineral deposits and appears black or brown.
