    • Mammals are a very diverse group!

      • Some mammals can fly, while others walk on land.
      • Mammals have adapted to live in a variety of habitats.
    • Mammals can further be divided into three groups:
      • Monotremes
      • Marsupials
      • Placental mammals
        • Let’s look a little more closely at each of these groups!
    • What are MONOTRMES ?
      • Monotremes are primitive, egg-laying mammals.
      • Example: duck-billed platypus
    • What are MARSUPIALS ?
      • Marsupials give birth to very underdeveloped young.
      • The young then develop in the mother’s pouch .
      • Examples: kangaroos and koalas
    • What are PLACENTAL mammals?
      • Placental mammals give birth to more developed young .
      • Placental mammals have a longer gestation period than marsupials.
      • Examples: humans and dogs
    • The diets of mammals differ as well.
      • Some mammals are carnivores .
        • Eat meat (other animals)
        • Examples: dolphins and tigers
      • Some mammals are herbivores .
        • Eat plants
        • Examples: cows and pandas
      • Some mammals are omnivores .
        • Eat both plants and meat (other animals)
        • Examples: people and some bears
      • Some mammals are insectivores .
        • Eat insects
        • Examples: aardvark and anteaters
