A new invasive species has turned up in Lake Superior, the bloody red shrimp. The U.S. Fish and Wildlife Service says researchers found a single specimen of the tiny shrimp in the Duluth-Superior harbor last summer. There are now documented findings of bloody red shrimp in all of the Great Lakes. They were first found in Lake Ontario and Lake Michigan in 2006.
Around the Great Lakes, millions of dollars are spent to fight invasive species like Asian carp. But when scientists find a new animal or plant in the area, it’s not always clear if it’s harmful or helpful.
