Zebra mussels originated in the Balkans, Poland, and the former Soviet Union. Biologists believe the zebra mussels were picked up in a freshwater European port in the ballast water of a ship and were later discharged into the Canadian side of Lake St. Clair (blame the Canadians again, eh). A female zebra mussel begins to reproduce at 2 years of age, and produces between 30,000 and 1 million eggs per year.
I took these pictures when we were swimming on the Upper Rideau Lake last weekend. They stick like snot to a steel pole in -30 degree C. Did I mention that I hate these damn things?
Wear water shoes when swimming folks, these little bastards are like razors if you step on them just the wrong way.
