Abstract: An animal is a living organism taxonomically assigned to the classification kingdom known as Animalia.Animals possess certain characteristics that distinguish them from members belonging to the other kingdoms of living organisms (Plantae, Fungi, Protista, and Monera; the latter kingdom is often replaced by Archaea and Bacteria).Animals usually lack chlorophyll and the ability to manufacture foods from raw materials available in the soil, water, and atmosphere.Animals generally are limited in their growth, and most have the ability to move in their environment at some stage in their life history
