The Animal Kingdom is a group of living beings that includes a wide variety of species, from invertebrates such as insects, crustaceans and molluscs, to vertebrates such as fish, birds, reptiles, mammals and humans. They are characterized by their ability to move, the absence of chlorophyll and the presence of cells with a defined nucleus. Most animals are heterotrophic, that is, they feed on other living beings or on organic materials. The Animal Kingdom is an important category for biological classification and for understanding Earth's biodiversity.
