taxa
Organisms' categorical divisions
Taxa is the plural of taxon, a group of organisms classified together—a species, genus, family, or any other rank in biological taxonomy.
Scientists study relationships between taxa to understand evolution: The analysis included taxa from three continents.
Higher taxa like phyla encompass millions of species.
