Zebra mussels

Zebra mussels

At Lake Ontario in Canada, zebra mussels cling to the inside of a rusty pipe. Zebra mussels, native to Russia, have become an invasive species in the United States and Canada. The mussels were most likely introduced to the Great Lakes in the holds of ships sailing from the ocean through the St. Lawrence Seaway. Since they were first detected in 1988, zebra mussels have disrupted local ecosystems and blocked the water intakes of factories, nuclear power plants, and municipal filtration plants.
