What Is a Mammal?

A mammal is a type of vertebrate animal that belongs to the class Mammalia. Mammals are characterized by several unique features that distinguish them from other animals:

Key Characteristics of Mammals

  1. Warm-blooded: Mammals regulate their body temperature internally, maintaining it at a constant level regardless of the environment.
  2. Hair or Fur: All mammals have some amount of hair or fur on their bodies at some stage of life.
  3. Mammary Glands: Female mammals possess mammary glands that produce milk to feed their young.
  4. Live Birth: Most mammals give birth to live young (with a few exceptions like monotremes, which lay eggs).
  5. Vertebrates: Mammals have a backbone or spine.
  6. Three Middle Ear Bones: Mammals have three bones in the middle ear (the malleus, incus, and stapes) which aid in hearing.
  7. Diaphragm: Mammals have a diaphragm, a muscle that helps in breathing.
