  1. ANIMAL KINGDOM CLASSIFICATION Animals can be grouped into two large categories: Vertebrates and Invertebrates. Vertebrates have backbones and invertebrates DO NOT.

  2. Invertebrates • 95% of all animals are invertebrates! The major phyla of invertebrates are: • Phylum Porifera • Phylum Cnidaria • Phylum Platyhelminthes • Phylum Nematoda • Phylum Mollusca • Phylum Annelida • Phylum Arthropoda • Phylum Echinodermata

  3. Porifera These are the simplest invertebrates. All sponges are asymmetric They have no tissues, organs or organ systems. They just have specialized cells. They all live in water.

  4. Cnidarians Cnidarians do not have organs or organ systems. They have radial symmetry. They have a single body opening surrounded by tentacles. They have simple tissue to carry out body functions. They have specialized cells to capture food.

  5. Echinoderms Radial symmetry Hard plates embedded in the skin Live only in oceans Complete digestive systems Tube feet Include sea stars, sea cucumbers and sea urchins

  6. Platyhelminthes They have bilateral symmetry They have nerve, muscle and digestive tissues They have a simple brain They have soft, flattened bodies Have a mouth Most are parasites.

  7. Nematoda Roundworms Bilateral symmetry Nerve muscle and digestive tissues Simple brain Round bodies with mouth and anus

  8. Mollusks Bilateral symmetry Soft bodies Some have hard shells Digestive system with two openings Body cavity with heart, stomach and other organs. Eyes and a simple brain Must remain wet

  9. Annelids Bilateral symmetry Soft bodies Circulatory system Simple brains Includes earthworms, leeches, etc.

  10. Arthropods Includes insects, spiders, shrimp, crab and relatives Insects, arachnids and crustaceans Bilateral symmetry Exoskeletons Jointed appendages
