Sylvilagus is a genus of rabbits commonly known as cottontails. These small mammals are characterized by their short, fluffy tails and long ears. They are primarily found in North America, with various species adapted to different habitats, including forests, grasslands, and deserts. Cottontails are herbivorous, feeding on grasses, herbs, and shrubs. These rabbits are known for their agility and speed, which help them evade predators such as foxes and hawks. Sylvilagus species are also social animals, often living in groups. They play a crucial role in their ecosystems by serving as prey for larger animals and contributing to plant growth through their grazing habits.
