Genus (/ ˈ dʒ iː n ə s /; pl.: genera / ˈ dʒ ɛ n ər ə /) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. [1] In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
The basic ranks are species and genus. When an organism is given a species name it is assigned to a genus, and the genus name is part of the species name. The species name is also called a binomial, that is, a two-term name. For example, the zoological name for the human species is Homo sapiens. This is usually italicized in print or underlined ...

Systematic biology (hereafter called simply systematics) is the field that (a) provides scientific names for organisms, (b) describes them, (c) preserves collections of them, (d) provides classifications for the organisms, keys for their identification, and data on their distributions, (e) investigates their evolutionary histories, and (f ...
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon ...

For example, the name of the coelacanth, Latimeria chalumnae which means "Latimeria of Chalumna", is a reference to the area near the mouth of the Chalumna River in the Indian Ocean, where the coelacanth was first found, i.e. its type locality. An adjective which must agree in case and gender with the genus: Felis silvestris ("the forest cat")
There are currently 1,258 genera, 161 families, 27 orders, and around 5,937 recognized living species of mammal. [1] Mammalian taxonomy is in constant flux as many new species are described and recategorized within their respective genera and families.
