Mammals are defined by some basic characteristics. They are endotherms, which means that they can maintain their body temperature. The females have mammary glands which produce milk for nourishment of the young ones after they are born. Hair is another important feature in mammals and it is present on their body, it may cover the entire body of some mammals while other may have it on certain parts of their body.
They have three bones in their middle ear. Their circulatory system is highly efficient. A four-chambered heart is one of the exceptional features of mammals. All mammals breathe air this does not exclude the mammals that live under water, we can see them coming to the surface to breathe. The lungs, again an important characteristics, play an important role in the exchange of oxygen and carbon dioxide.
Though mammals share certain attributes, some of them do distinguish themselves from the crowd. All mammals have 4 legs except whales, dolphins, dugongs and manatees which have lost their hind limbs in the process of evolution. Mammals usually have 7 neck vertebrae. However the manatee and two-toed sloth have 5-7 neck vertebrae, while the three-toed sloth has 8-9 neck vertebrae.
Teeth are replaced only once in their life cycle. The exceptions to this rule are pygmy rock-wallaby, silvery mole-rats and manatees, whose teeth are continuously replaced during their lifetime.
