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