Muskrats are medium-sized rodents native to North America, known for their semi-aquatic lifestyle. They typically inhabit wetlands, marshes, and riverbanks, where they build burrows or lodges made of reeds and mud. Muskrats have a long, slender body, webbed hind feet, and a flat tail, which helps them swim efficiently. These animals primarily feed on aquatic plants, roots, and some small animals. Muskrats play a vital role in their ecosystems by helping to maintain wetland health and providing food for predators like otters and birds of prey. Their populations can fluctuate based on environmental conditions and habitat availability.
