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.
Related subspecies are less distinct than species of the same genus. Generally speaking, two related subspecies can successfully interbreed but two species cannot. If a subspecies can be shown to be different enough, it can be elevated to species status.
