Binomial nomenclature for species has the effect that when a species is moved from one genus to another, sometimes the specific name or epithet must be changed as well. This may happen because the specific name is already used in the new genus, or to agree in gender with the new genus if the specific epithet is an adjective modifying the genus ...
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages.
Zoological nomenclature is independent of other systems of nomenclature, for example botanical nomenclature. This implies that animals can have the same generic names as plants (e.g. there is a genus Abronia in both animals and plants).
A taxon above the rank of species has a scientific name in one part (a uninominal name). A species has a name typically composed of two parts (a binomial name or binomen): generic name + specific name; for example Canis lupus. Sometimes the name of a subgenus (in parentheses) can be intercalated between the genus name and the specific epithet ...
For example, verus is listed without the variants for Aloe vera or Galium verum. The second part of a binomial is often a person's name in the genitive case, ending -i (masculine) or -ae (feminine), such as Kaempfer's tody-tyrant, Hemitriccus kaempferi. The name may be converted into a Latinised form first, giving -ii and -iae instead.
Normally the seven "major ranks" appear as shown here, but in cases where more detail is appropriate, "minor ranks" may appear as well. For example, a subfamily may appear between family and genus. Binomial Name The binomial name, binomial nomenclature or "binomen" is the currently accepted scientific name for a species. It consists of the name ...
“The emperor penguin is the largest penguin species on Earth.” The emperor penguin is the largest species of penguin in the world and also one of the most unique. Instead of breeding in the ...
In botanical nomenclature, "name" always refers to the whole name (of a species or otherwise), whereas in zoological nomenclature it can refer to either part of the binomen. Thus Hedera helix (common ivy, English ivy) is the name of the species; Hedera is the name of the genus; but helix is called the specific epithet, not the specific name. [2]
