The mink is the most common water mammal predator (meat eater) in Minnesota. This excellent little swimmer can be found in nearly every wetland, lake, and stream in the BWCA, so keep your eyes open as you canoe those beautiful lakes.  The mink eats nearly all creatures that live at the water, including small fish, crayfish, ducks, and water mammals. The mink is small and long (14-20" long including its 5-9" tail, weighing 2-4 lbs.), with small rounded ears, light to dark glistening fur, and a white or yellowish belly and chest.
