Bloody red shrimp were first found in lakes Ontario and Michigan in 2006, according to the Fish and Wildlife Service. They’re now documented in all the Great Lakes.

The species eats waterfleas and algae. They can become food for bigger fish, and competition for smaller ones, according to the University of Wisconsin’s Sea Grant Institute.”
