Muskegon, Michigan - European invader found in channel
A species of shrimp previously found only in the seas of eastern Europe has now been discovered half a world away -- in the Muskegon Lake Channel.
Thousands of bloody red mysid, Hemimysis anomala, were discovered in the channel in November. It is the most recent addition to a list of Great Lakes invader species that now numbers more than 180.
Researchers at the National Oceanic and Atmospheric Administration's Lake Michigan Field Station who found swarms of bloody red mysid said the half-inch-long shrimp were likely imported to the Great Lakes in the ballast water of an oceangoing freighter.
