Mammals are the only living organisms to have hair or fur. This helps to keep the mammal warm. All mammals have four-chambered hearts. Mammals are also endothermic which means that no matter what their surroundings are they can maintain there body temp.
Mammals also have mammary glands which secrete milk. This aids in the way mammals nurse their young. Mammals also have a sheet of muscle called the diaphragm. This allows the chest cavity to expand allowing the mammal to breathe.
Mammals also give live birth. They also have a very developed brain and nervous system which gives them the ability to learn. Mammals also have modified limbs. They have different types of teeth which are modified to the types of food they eat.
