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.pecies hypothesized to have the same ancestors are placed in one genus, based on similarities. The similarity of species is judged based on comparison of physical attributes, and where available, their DNA sequences.
