This is my fourth post about snakeheads this month, but how could I avoid reporting that the Northern snakehead (Channa argus) has been found in Chicago? The email about it arrived in my inbox today via the NAS Alert System - you can view the specimen record here. The adult fish was found in Lake Michigan, a first for Illinois and a first for the Great Lakes ecosystem. Of course the story is making the media rounds, with liberal use of words like "Frankenfish" and "terror." Read about it in the Chicago Sun-Times, the Duluth News-Tribune, or MLive.com.
