The muskrat or common muskrat (Ondatra zibethicus) is a medium-sized semiaquatic rodent. Adult muskrats weigh 0.6–2 kg (1+1⁄4–4+1⁄2 lb), with a body length (excluding the tail) of 20–35 cm (8–14 in). They are covered with short, thick fur of medium to dark brown color. Their long tails, covered with scales rather than hair, are laterally compressed and generate a small amount of thrust, with their webbed hind feet being the main means of propulsion and the unique tail mainly important in directional stability. Muskrats spend most of their time in the water and can swim underwater for 12 to 17 minutes. They live in families of a male and female pair and their young. Wikipedia →
