  1. ZEBRA MUSSELS

  2. West Asia • Live in the drainage basin in the Black, Aral, and Caspian Sea • Invaded many bodies of water in Europe, the Netherlands, and northeastern Poland • They are microscopic with a yellow or brown shell • They can grow very big. • Able to tolerate many environmental conditions which makes it hard to kill them

  3. Why are they here • Not completely known • Believed that there are here accidentally • Came on European cargo ships into the Great Lakes on the east side of America • In 1988 was their 1st discovery in Lake St. Clair • 1992 they were found in Wisconsin and as far as Mississippi. • Now they are in New York too

  4. Known as aqueduct hitchhikers • Attach themselves to objects or other animals • Messing up the food chain because they get into fragile systems and consume critical amounts of these microscopic organisms • They could increase exposure to organic pollutants because they could rabidly accumulate so much with their tissues • Eat animals and algae which is also the food for larval fish • Zebra mussels filter water; up to a quart of water per day • Because of this mussels causes a related and frequently dramatic increase in water clarity in infested lakes and rivers. • Severely effect native mussels and clams by inferring with their feeding
