Shrimply The Worst  

The Milwaukee Journal Sentinel is reporting that a new non-native species of shrimp, Hemimysis anomala has been discovered in the Great Lakes. The shrimp, considered native to both the Caspian Sea and the Black Sea, was found in great numbers this past November, near Muskegon port in Lake Michigan. Because that port does not see a lot of international traffic, it is thought that the shrimp were originally introduced elsewhere in the lake - biologists are expecting to find more populations closer to the point(s) of origin.

The article notes that two Canadian researchers predicted (.pdf) the arrival of this very species over eight years ago - it is the 183rd recorded in the Great Lakes, if you're keeping count :-).
