A species is designated in italics by the genus name followed by the specific name, for example Felis domesticus (the domestic cat).
In biology, a species (abbreviated sp. , with the plural form species abbreviated spp. ) is one of the basic units of biological classification and a taxonomic rank.A species is often defined as the largest group of organisms where two hybrids are capable of reproducing fertile offspring, typically using sexual reproduction.While in many cases this definition is adequate, the difficulty of defining species is known as the species problem.he first part of a binomial is the generic name, the genus to which the species belongs. The second part is either called the specific name (a term used only in zoology) or the specific epithet (the term used in botany, which can also be used in zoology).
