  1. Kingdom Animalia Animal Charactersitics Dermal Layers Body Plans & Symmetry

  2. What is an animal? • Name an animal. Any animal. • Consider the list we’ve created. • What do they ALL have in common?

  3. What is an animal? • Heterotrophic • Digest food inside the body • Cells: eukaryotic, specialized, multicellular • Typically display Locomotion • MOST reproduce sexually • NO CELL WALLS

  4. Animal Development http://www.esu.edu/~milewski/intro_biol_two/lab_animal_development/32_02EmbryonicDev_3-L.jpg

  5. Animal Development • Sperm + egg (gametes) = fertilization • Zygote (initial diploid cell) • Blastula (hollow ball of cells) • Gastrula (cells on one side fold inward; 2-layers with an opening at one end)

  6. Animal Development • Endoderm: inner cells (digestive tract) • Ectoderm: outer cells (skin & nerves) • Mesoderm: “middle layer” (muscles, circulatory, excretory, respiratory) • Protostome (mouth first) • Deuterostome (anus first)

  7. Body Plans (Symmetry) http://userwww.sfsu.edu/biol240/labs/lab_16animalbodyplan/pages/bodyplan.html

  8. Body Plans (Cavities) http://userwww.sfsu.edu/biol240/labs/lab_16animalbodyplan/pages/bodyplan.html

  9. Animal Diversity • There are many phyla of animals, generally divided into two groups: • Invertebrates (phyla such as: porifera, cnidaria, planaria, arthropoda, etc.) – NO BACKBONE • Vertebrates (phyla Chordata) – HAVE Backbones
