Muskrats are rodents that look like a cross between a rat and a beaver. They live in water. The animal has two musk glands under its tail. It produces a strong odor that smells like musk. Muskrats were originally found only in North America. People took them to Europe and Asia in the early 1900s. The scientific name of the muskrat is Ondatra zibethicus.
Muskrats build their houses in water, using mud, cattails, and other plants. These structures are typically more than one meter high and several meters broad. Muskrats dig narrow channels through the surrounding plant growth.
