Facts about Muskrats
- 09
Prized for their dense, waterproof fur, muskrats were among the most commercially trapped animals in North America throughout the 19th and 20th centuries.
- 08
In North America, muskrats consume approximately 1.3 pounds of aquatic plants daily, making them significant herbivores that can reshape wetland vegetation composition through selective feeding.
- 07
Muskrats can excavate burrows up to 4 feet deep in wetland banks, creating tunnel systems with multiple chambers and escape routes to avoid predators like minks and otters.
- 06
A muskrat's tail comprises approximately 40 percent of its total body length and functions as a rudder for swimming, a fat storage organ, and a thermoregulation tool in aquatic environments.
- 05
Ondatra zibethicus species have been introduced to Europe and Asia since the early 1900s, establishing invasive populations that damage wetland ecosystems across multiple continents.
- 04
Their musky scent glands produce a powerful odor that muskrats use to mark territory and communicate with potential mates during breeding season.
- 03
Muskrat populations can produce 2 to 3 litters annually with 6 to 7 kits per litter, allowing their numbers to increase rapidly in suitable wetland habitats.
- 02
During winter, muskrats construct dome-shaped lodges from cattails and mud that can measure up to 3 feet tall and house multiple family members in chambers above the waterline.
- 01
Weighing between 0.75 and 1.8 kilograms, muskrats can hold their breath underwater for up to 17 minutes while foraging for aquatic vegetation.
