They are typically brown or grayish in color, with a lighter underbelly, and can be found in wetlands, marshes, and along riverbanks, where they are known for their burrowing behavior and social structures.
FUN FACTS
- Nutria are known for their impressive swimming abilities, using their webbed feet to propel themselves through water at speeds of up to 5 mph
- They can also hold their breath underwater for several minutes while foraging for food
- | Despite being considered pests in some regions due to their feeding habits, Nutria are also farmed for their fur, which is used in various clothing and accessory products
- Their fur is water-resistant, making it particularly valuable in fashion
