The hierarchy of biological classification's eight major taxonomic ranks. A phylum contains one or more classes. Intermediate minor rankings are not shown. In biological classification, class (Latin: classis) is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank. It is a group of related taxonomic orders.
[10] [11] The classification also includes seven fresh-water biomes and 5 marine biomes. [10] Each biome contains many ecoregions that are examples of that type of habitat. [10] The purpose of this classification scheme is to identify ecoregions that are conservation priorities. These priority regions are referred to collectively as the WWF's ...
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, a kingdom is the second highest taxonomic rank, just below domain. Kingdoms are divided into smaller groups called phyla (singular phylum).
The following is an artificial synthesis, solely for purposes of demonstration of absolute rank (but see notes), from most general to most specific: [33] Superdomain Domain or Empire. Subdomain (biology) Realm (in virology) [24] Subrealm (in virology) [24] Hyperkingdom Superkingdom Kingdom. Subkingdom Infrakingdom Parvkingdom

In biological taxonomy, a domain (/ d ə ˈ m eɪ n / or / d oʊ ˈ m eɪ n /) (Latin: regio [1]), also dominion, [2] superkingdom, realm, or empire, is the highest taxonomic rank of all organisms taken together. It was introduced in the three-domain system of taxonomy devised by Carl Woese, Otto Kandler and Mark Wheelis in 1990. [1]
In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families.
