What Is a Mammal?

A mammal is a vertebrate animal that belongs to the class Mammalia.

This group has several distinct features:

• Warm-blooded Metabolism: Mammals maintain a constant body temperature regardless of the environment. In other words, they are endothermic animals.
• Hair or Fur: All mammals have some hair at some point in their lives.
• Mammary Glands: Female mammals possess mammary glands that produce milk to nourish their young.
• Live Births: Most mammals give birth to live young, though a few, like the platypus and echidna, lay eggs.
• Three Middle Ear Bones: Mammals have three distinct bones in the middle ear (malleus, incus, and stapes) that aid in hearing.
