#division.biological_group  (biology) a group of organisms forming a subdivision of a larger category
  supertype:  biological_group  a group of plants or animals
  subtype:  division_Archaebacteria  in some classifications considered a kingdom
  subtype:  division_Eubacteria  one-celled monerans having simple cells with rigid walls and (in motile types) flagella
  subtype:  division_Cyanophyta__Cyanophyta  prokaryotic organisms sometimes considered a class or phylum or subkingdom; coextensive with the Cyanophyceae: cyanobacteria (blue-green algae)
  subtype:  division_Schizophyta__Schizophyta  former term for the Cyanophyta
  subtype:  division_Heterokontophyta__Heterokontophyta  algae having chlorophyll a and usually c, and flagella of unequal lengths; terminology supersedes Chrysophyta in some classifications
  subtype:  division_Chrysophyta__Chrysophyta  mostly freshwater eukaryotic algae having the chlorophyll masked by brown or yellow pigment; yellow-green and golden-brown algae and diatoms: Xanthophyceae, Chrysophyceae, Bacillariophyceae; some some classification systems superseded or subsumed by Heterokontophyta
  subtype:  division_Phaeophyta__Phaeophyta  coextensive with class Phaeophyceae; in some classifications subsumed in the division Heterokontophyta
  subtype:  division_Euglenophyta__Euglenophyta  free-swimming flagellate algae
  subtype:  division_Chlorophyta__Chlorophyta  large division of chiefly freshwater eukaryotic algae that possess chlorophyll a and b, store food as starch, and cellulose cell walls; classes Chlorophyceae, Ulvophyceae, and Charophyceae; obviously ancestral to land plants
  subtype:  division_Rhodophyta__Rhodophyta  lower plants; mostly marine and littoral eukaryotic algae
  subtype:  division_Cynodontia__Cynodontia  a division of Triassic Therapsida comprising small carnivorous tetrapod reptiles often with mammal-like teeth
  subtype:  division_Dicynodontia__Dicynodontia  a division of Therapsida
  subtype:  Pisces  a group of vertebrates comprising both cartilaginous and bony fishes and sometimes including the jawless vertebrates; not used technically
  subtype:  form_division  an artificial taxonomic category for organisms of which the true relationships are obscure
