Mammals include humans and all other animals that are warm-blooded vertebrates (vertebrates have backbones) with hair. They feed their young with milk and have a more well-developed brain than other types of animals.
Mammals are among the most adaptable animals on the planet. They are found on every continent and in every ocean, and range in size from tiny bumblebee bats to enormous blue whales.
The term originates from the latin word mamma which means breast.
Female mammals feed their newborns with milk, which they produce from specialized glands, the mammary glands.
All modern mammals give birth to live young, except the five species of monotremes, which are egg-laying mammals.
Despite their differences, all mammals share four traits: hair, mammary glands, a hinged jaw, and three tiny middle ear bones. Most have specialized teeth and moveable external ears.
