Mammals are warm-blooded vertebrates that give birth to live young and produce milk to feed their babies. They have hair or fur and breathe air through lungs. Mammals live on land or in water and move by walking, running, jumping or swimming using two or four legs, though aquatic mammals do not have legs. Their tails are used for balance or movement depending on if they live on land or in water. Mammals are herbivorous, carnivorous or both, with aquatic mammals solely carnivorous.
