  1. Classifying Organisms by Structure

  2. By their observable structures How do we classify animals?

  4. Soft body, hard shell-mollusks, like clams • Tough outer skeleton, jointed legs- arthropods, like spiders Invertebrates

  5. Eating habits- omnivore, carnivore, herbivore • Cold-blooded or warm-blooded Vertebrates

  6. Symmetry-radial, bilateral • Appendages-legs, arms, wings, fins, tails • Respiration- lungs, gills, stomach-breathers Other types of classification
