  1. Tour of the Invertebrate Organisms of the Animal Kingdom Animal KingdomInvertebrates

  2. Invertebrates Are Animals • Animal Characteristics • Eukaryotic • Heterotrophic • Multicellular, specialized cells • Lack Cell Walls • Reproduce, sexual and asexual • Respond to environment • Motile, muscles

  3. Specifics to Invertebrates • Characterized by No Backbone! Other means of structure • Exoskeleton, Spicules, Shells, Pin, Hydrostatics • Invertebrate Fun Facts • 95% of all animal species • Sizes range from microscopic to 20 meters

  4. Classifying Invertebrates • Body Symmetry • Cephalization Level • Body Plan • Layers of Tissue • Early Development – Protostome or Deuterostome

  5. Major Groups • Crustacea • Platyhelminthes • Annelida • Porifera • Cnidaria • Insecta • Mollusca • Nematoda • Echinodermata http://school.discovery.com/clipart/ , http://clipart.usscouts.org

  6. Type of Body Plan acoelomate, coelomate Development of systems Circulatory Movement Things to Consider • Level of Classification • Phylum or Class • Common name examples for each • sea star • Type of Symmetry • bilateral

  7. Invert Tour Title-Invert Tour- Animals without a backbone. They share the LACK of a trait. Purpose- Observe and gather information to compare/contrast Invert groups. Observations and Notes-

  8. Conclusion-Reference chapters 26-29 Dragonfly Which invert groups do you believe are the LEAST complex? WHY? Which invert groups do you believe are the MOST complex? WHY? 3. List your evolutionary ranking from LEAST to MOST complex. 1. 2. 3. 4. 5. 6. 7. 8. 9. 4. How does YOUR RANKING compare to the BOOK model? (pgs 747-749) Explain in detail your ranking differences and similarities.
