What format is used when writing a scientific name?

The correct format for writing a scientific name follows the binomial nomenclature system, which was developed by Carl Linnaeus. This system specifies that the scientific name of an organism must include the genus name followed by the species identifier, both of which are italicized when printed.

Using "Genus species" is the standard convention: the genus name is capitalized, while the species name is written in lowercase. Italicizing the name serves to distinguish it from other text and indicate that it is a formal scientific designation. This system allows for precise communication among scientists regarding species identification and classification, reducing confusion that could arise from common names. The other formatting styles listed do not conform to the scientific naming conventions recognized in biology.
