You should answer the following objectives.  

The student will:

1. Describe general appearance and life history of sharks.

2. Explain the concept "negatively bouyant".

3. Describe how sharks swim compared to rays and skates.

4. Describe the sense organs of chondrichthyes.. Explain
       how their sense organs reflect the differences in their lifestyle.

5. Describe how sharks locate their food.

6. Describe some species of sharks and compare their      
    morphology with their habitat.

7. Distinguish between skates and rays. Describe how 
    skates and rays swim.

8. Describe local species of skates and rays.
