Classification of animals. All around the world many different types of animals are present. Many animals are quite similar to each other while others are different from others. So animals can be classified based on their similarities. The whole animal kingdom is divided into two main groups. They are Vertebrates and Invertebrates.
The world's three great groups of mammals: monotremes, marsupials and placentals are all found in Australia. Monotremes - egg-laying mammals (nowadays found only in Australia and New Guinea) Marsupials - babies born in embryonic condition and kept firmly attached to a teat in a pouch or nestled behind a protective skin-flap while developing further.
