Where did the zebra mussels that invaded the Great Lakes come from?
The zebra mussel (Dreissena polymorpha) is a small freshwater mussel. The species was originally native to the lakes of southern Russia and Ukraine, but has been accidentally introduced to numerous other areas and has become an invasive species in many countries worldwide.
How did zebra mussels get to Michigan?
Known in Latin as Dreissena polymorpha, meaning “many forms,” the mussel is remarkably adaptable. The Dreissana was accidentally introduced into this country in 1986, arriving in the hold of a ship from the Caspian Sea.

They kill native mussels; coat surfaces with razor-sharp shells; foul anchor chains; block water intake pipes; and steal plankton and other food from native fish.
Are there zebra mussels in Lake Superior?
