2. The Zebra Mussel is
about 1 inch long or
the size of a
thumbnail.
They are yellow and
brown with zebra
looking stripes.
Careful! They have
extremely sharp
edges!
They tend to stick
together, so if you
find one, you're sure
to find more!

3. Zebra mussels
came from
Western Asia
and Eastern
Europe.
This map
shows where
Zebra mussels
are invading
the most and
the least.

5. They got here by
sticking
themselves on…
Boats
Paddles
Motors
Turtles
Clams
Crayfish
Also came as
larvae in ballast
water.

6. Well, Zebra
mussels …
Filter water by
feeding on
microscopic
plants and
animals
This makes the
water clearer
(which is NOT
good)
Eat native fish
Produce blue-
green algae

7. Zebra mussels…
Clog water intake
pipes
Stick to docks, piers,
plants and buoys.
In 1989, the town
of Monroe,
Michigan lost its
water supply for 3
days because of a
massive clump of
Zebra Mussels
clogging the water
intake pipes!

8. Water users in the
Great Lakes region
are paying a total of
$30 million annually
to monitor and
control Zebra
Mussels! Wow!
We are also removing
them when we see
them.
Two friends of mine,
when they found
Zebra Mussels, they
took a rock and
smashed them!

9. Well YOU can…
Clean the bottom
of your boat
before entering
another lake
Clean paddles off
with hot water
Report any
sightings of zebra
mussels to water
authorities

10.  Ballast water- water that sits in a tank in a ship.
To lower the ship, water is collected. To bring the
ship up, water is released
 Microscopic- too tiny to see. A microscope is
needed to see
 Larvae- a small egg
