Currently, textbooks from the United States use a system of six kingdoms (Animalia, Plantae, Fungi, Protista, Archaea, and Bacteria)
Protozoa (Protista)• single cell• microscopic to 5mm• cousins with foraminifera (shells form limestone-
which is what the Egyptian pyramids were made of)
• Important in soi, ocean, and fresh water food chains
• can carry disease (Plasmodium vivax) – ex Malaria
Amoeba proteus
Volvox sp.
Paramecium
Vorticella
Stentor
Euglena
Amoeba proteus
Difflugia sp. Didinium Eats green alga (Spirogyra) Eats Paramecium
Blepharisma Bursaria truncatella Spirostomum
Phylum- Porifera (sponges)
• Among the simplest, multicellular animals
• Unspecialized tissues• No organs
Phylum- Cnidaria
• Hydra• Freshwater• Simplest animals with
definite tissues• Stinging tentacles (filled
with nematocyst threads)
• Up to 25 mm• Ability to regenerate lost
body parts

• Bilateral symmetry• Internal reproductive system• Layers of muscles• Simple nervous system• Exhibit an ability to learn• Free living (not parasitic)
Phylum- Arthropoda
