Muskrat are a semi-aquatic, medium-sized rodent that is widespread in Alaska. You'll usually spot them near wetlands as they forage for edibles or swimming in streams and lakes. Their bodies are less sensitive than most other mammals to the build-up of carbon dioxide, which allows them to be under water for up to 17 minutes. Humans continue to rely on them as an important source of food and fur in some parts of the world.
