Compare animals:
- earthworm
- clam
- grasshopper
- fish
- frog
and research the anatomy of these body systems:
- digestive
- nervous
- respiratory
- cardiovascular
- excretory/osmoregulatory
1. Identify 2-3 similar anatomical structures that appear in allthe animals for which there were posts. Why do you think thesestructures have remained similar even though these animals are fromdifferent phyla?
2. Which of these animals live on land and which live in thewater? Discuss which anatomical features are specifically adaptedto each environment.
3. Animals need to exchange molecules with the environment tosupport their metabolic rate and we see that they often optimizethis by increasing surface area. Where specifically do you see themaximization of surface area among these organisms?
