12For a gentleman should know something of invertebrate zoology, call it culture or what you will, just as he ought to know something about painting and music and the weeds in his garden.Martin Wells, Lower Animals, 1968
13The Six Kingdoms of Life THE PROKARYOTES (the “domains” Eubacteria and Archaea)Kingdom Eubacteria (Bacteria)Kingdom Archaea (Archaebacteria)THE EUKARYOTES (the “domain” Eukaryota, or Eukarya)Kingdom FungiKingdom Plantae (= Metaphyta)Kingdom ProtistaEukaryotic single-celled microorganisms and certain algae. A polyphyletic grouping of perhaps 18 phyla, including euglenids, green algae, diatoms and some other brown algae, ciliates, dinoflagellates, foraminiferans, amoebae, and others. Many workers feel that this group should be split into several separate kingdoms to better reflect the phylogenetic lineages of its members. The 80,000 described species probably represent about 10 percent of the actual protist diversity on Earth today.Kingdom Animalia (= Metazoa)The multicellular animals. A monophyletic taxon, containing 34 phyla of ingestive, heterotrophic, multicellular organisms. About 1.3 million living species have been described; estimates of the number of undescribed species range from lows of 10–30 million to highs of 100–200 million.
