Tiny Eurasian exotic is upending watery ecosystems across the northern Great lakes The zooplankton never saw it coming.
which is why the spiny water flea aka Bythotrephes (pronounced BITH-oh-TREH-feez) is devouring its way through the Great lakes and into the surrounding inland waters.
Like many aquatic invasive species it was transplanted by ships loading ballast in one part of the world and dumping it in another in this case the Great lakes.
But it is having a field day in a band of inland lakes stretching from eastern Ontario to northern Minnesota and in the cooler Great lakes.
The primary highway for invasive aquatic species the ballast tanks of oceangoing vessels entering the Great lakes is still open.
They can pick up something in the southern Great lakes and pollute Thunder Bay or Duluth said Kerfoot.
