 * 1) Explore the type of symmetry that each organism has. **Pig=Bilateral, Starfish=Radial, Crayfish=Bilateral**
 * 2) Label a picture of the organism with these terms: anterior, posterior, dorsal, ventral, lateral, head, thorax, abdomen.

3. What is the advantage of various structures found on the body such as appendages, mouth parts, sensory antennae, skin receptors, etc. Discuss all the different types of receptors.
