In biology, a kingdom is the top-level, or nearly the top-level, grouping of organisms in scientific classification. Originally, two kingdoms were distinguished, the Animalia (animals), which typically could move about, and the Plantae (plants), which typically could not.
The hierarchy of biological classification's eight major taxonomic ranks. A domain contains one or more kingdoms. Intermediate minor rankings are not shown. In biology, kingdom (Latin: regnum, plural regna) is the second highest taxonomic rank, just below domain. Kingdoms are divided into smaller groups called phyla.
