4. Symmetry
Bilateral – divided in half by a line, parts are mirror images
Radial – body parts arranged around a central point
Asymetrical – can’t be evenly divided, no symmetry

5. Vertebrates Invertebrates
Have backbones and endoskeletons
Cold blooded (ectothermic) or warm blooded (endothermic)
Five Groups

Mammals
97% of ALL animals
No backbones
Exoskeletons

6. Metamorphosis
Many invertebrates (and some vertebrates) go through the process
A change in body form as the life cycle continues
