2. So that each person in the class reports on a different animal, post the common name as well as the generic and species names of the animal you picked to the assignment database. If someone else has already posted that animal, pick another and post it. Do not duplicate animals. Pick an animal early.

3. What is the complete scientific classification of this animal? What source(s) did you use for reference?

4. Describe each animal's adaptations to nitrogen excretion:

a) Describe the physiological aspects of its adaptation. What source(s) did you use for reference?

b) Describe the anatomical structures that adapt it. What source(s) did you use for reference?

c) State the form of nitrogen the animal excretes. What source(s) did you use for reference?

d) Compare this animal's nitrogen adaptation to that of humans: does it conserve more or less water than humans? What source(s) did you use for reference?
