In biological classification, subspecies (abbreviated  subsp.  or  ssp. ; plural : subspecies) is either a taxonomic rank subordinate to species, or a taxonomic unit in that rank.
A species is a group of individual organisms that interbreed and produce fertile, viable offspring. According to this definition, one species is distinguished from another when, in nature, it is not possible for matings between individuals from each species to produce fertile offspring. Members of the same species share both external and internal characteristics which develop from their DNA.
