Common Names: Muskrat
A very successful animal over a wide range of climates and habitats. Muskrats spend much of their time in the water and are well suited for their semi-aquatic life, both in and out of water. Muskrats can swim under water for 12 to 17 minutes. Their bodies, like those of seals and whales, are less sensitive to the buildup of carbon dioxide than those of most other mammals. They can close off their ears to keep the water out. Their hind feet are semi-webbed, although in swimming the tail is their main means of propulsion.The muskrat's name comes from the two scent glands which are found near its tail; they give off a strong 'musky' odor which the muskrat uses to mark its territory.
Found in wetlands, near ponds and lakes.
