Muskrats are semi-aquatic rodents native to North America, known for their long, rat-like tails and webbed hind feet. They typically inhabit wetlands, marshes, and riverbanks, where they build burrows or lodges from vegetation. Muskrats are primarily herbivorous, feeding on aquatic plants, but may also consume small animals and fish. They play a vital role in their ecosystems by helping to maintain wetland environments.
