In zoology, the formation of a scientific name for an organism follows a strict set of rules adopted by the International Commission on Zoological Nomenclature. This International Code of Zoological Nomenclature serves to promote the stability, accuracy, and universality of an organism's scientific name. Every proposed scientific name must be unique and distinct from all other names. In this way, every named organism is a distinguishable entity. However, scientific names are not always stable.
