A hopping mammal is a mammal that moves by jumping or hopping. Two examples of hopping mammals are rabbits and hares. Rabbits have six letters in their name, while hares have four letters in their name. Both animals are small mammals with long ears and short tails. They are both herbivores, meaning they feed on plants. Rabbits and hares are found in many parts of the world, including North America, Europe, and Asia.
