What Is The Difference Between Taxon And Species?

The hierarchy can be represented as Kingdom subgrouping into Phylum for animals or Division for plants, Class, Order, Family, Genus and Species. Hence, the basic unit of classification is species.
Taxon is the representation of any level of the taxonomic category. It is constructed by individual biological objects. Taxon can be of monophyletic or polyphyletic generation.
Species includes all the organisms that are similar to breed and produce fertile offspring. Species is one taxonomic category and is an abstract term. Species is always monophyletic

Nomenclature is the system of scientific names for taxa (such as species, genera, or families) and the rules and conventions for the formation, treatment, and use of those names. It follows an internationally agreed, quasi-legal procedure. Taxonomy is the identification and interpretation of natural groups of organisms (i.e., taxa) based on characters (such as morphology, genetics, behaviour, ecology). The discovery and delimitation of taxa is a science. Nomenclature and taxonomy are closely allied, but separate aspects ordering information about biodiversity. They overlap in the definition of type specimens, which tie the name to a single physical standard.
