The muskellunge is an extremely large and heavy fish that lives in the dark waters of northern Michigan, northern Wisconsin and northern Minnesota and in the Mississippi valley. They can swallow their food in one gulp and eat prey up to 30% of their total length. Humans can choke on popcorn. Theyre also top predators without having to use weapons. With rows of sharp, nasty teeth, they can lock larger prey into place until it gives up. Muskies, as theyre affectionately called, even sometimes attack humans, leaving large wounds and making great content for shows like MonsterQuest.
