Ondatra zibethicus
Named for the odoriferous secretions from their perineal glands, Muskrats are large aquatic voles with webbed hind feet and a laterally flattened tail. They range in size from about 16-26 inches in length, and weigh between 2 to 4 pounds. Although they can be seen during the day, they are most active at night. They build dome-shaped homes, called a lodge, and also live in dens and burrows. Although primarily herbivorous, they will consume animal matter.
