Animals

                                        More than a million and a half species of animal have been identified, and there are many millions more yet to be discovered. Animals are living organisms found in nearly all of the Earth's habitats, including the depths of the oceans, the freezing Arctic, and even inside other animals and plants. The animal kingdom is divided into animals without backbones (invertebrates),such as snails and lobsters, and animals with backbones (vertebrates), such as frogs and monkeys. Invertebrates make up 97 per cent of all animal species.
