The document describes the key characteristics of the Animal Kingdom. It is the most complex kingdom and consists of multicellular organisms that obtain food externally, move to find food, and digest food internally. Animals are divided into invertebrates without backbones and vertebrates with backbones. The nine phyla of the Animal Kingdom are described as Porifera, Cnidaria, Flatworms, Roundworms, Mollusca, Echinoderm, Arthropoda, and Chordata. Examples are provided for each group's distinguishing features.
