There are
many different types of animals in the world. When we think of an animal, we
usually think of something like a cat, a dog, a mouse, or a tiger. They live on
land and in the water. All these different animals belong to a group called
Animal Kingdom. Around 800.000 species have been identified in the Animal
Kingdom – most of them are in the Arthropod phylum.
Many
animals are quiet similar to each other. Some others are quiet different.
Animals can be classified based on their similarities. Animal Kingdom can be
split up into two main groups, vertebrates (with a backbone) and invertebrates
(without a backbone).
Some
scientists believe that if they were to identify all species in the tropical
rainforest, they would find that there more then ten thousand species of
arthropod. Many people do not think that clams, jellyfish, or earthworms are
animal. Yet, all of them belong to the kingdom of animal.
