The Classification of animals :
Animal Kingdom can be split up into main groups, vertebrates (with a backbone) and invertebrates (without a backbone). When you think of an animal, you usually think of something like a cat, a dog, a mouse, or a tiger.
All told, around 800,000 species have been identified in the Animal Kingdom — most of them in the Arthropod phylum.
