Mammals are a diverse group of warm-blooded vertebrates known for their unique features.
Animals in this group have hair or fur at some point in their life, serving purposes like insulation and camouflage.
Mammals are equipped with mammary glands to produce milk for their offspring. Their lower jaws consist of a single bone, the dentary, enabling a strong bite and diverse diet.
Furthermore, mammals possess three middle ear bones and a neocortex in the brain specialized for advanced sensory functions.
The majority give birth to live young, except for monotremes such as the platypus and echidnas, which lay eggs.
