Read an Excerpt

Zebra mussel

Dreissena polymorpha

Other Common names: none

Description: under 1 inch (up to 2); black to brownish “D”-shaped shell, generally with alternating dark and light stripes (zebra-like); usually in clusters of individuals; on smooth surfaces, young feel like fine sandpaper, juveniles are peppercorn-size

Compare: zebra mussels can sit flat on their ventral (lower) surface, quagga mussels (page 44) cannot

Habitat: attaches to hard surfaces (rocks, logs, boats, docks, etc.); generally in shallow (6–30 feet), algae-rich water of lakes, rivers, canals, ponds

Origin: native to Eastern Europe; introduced to Great Lakes in late 1980s by ballast water; spread to the Mississippi River, its tributaries and inland lakes

Spread by: recreationists transporting mussels attached to aquatic plants, boats, nets, fishing equipment and in water; produces several hundred thousand microscopic eggs per season

How you can help: Zebra mussels are now found in all the Great Lakes and many U.S. states. The cost of prevention and control is estimated to exceed $500 million annually.

  • CLEAN, DRAIN, DRY (page 20)
  • Report new sightings to your state’s natural resource agency (page 128); note date, exact location (page 130) and include a photograph, if possible
  • Place specimen in a sealed plastic bag (or in rubbing alcohol) and report

    Impact on You: Zebra mussels are a serious problem and can encrust boat hulls, piers and moorings. Larvae drawn into boat engine intakes can colonize the interiors of engine cooling systems

  • Disrupts aquatic food web
  • Facilitates nuisance plant growth
  • Sharp shells littering beaches can make a stroll hazardous
  • Smothers native clams/mussels (many are rare) and crayfish
