Using the examples from the animals you have studied in this lab, give the differences between the following phyla: Echinodermata and planaria Cnidaria and Porifera Annelida and Nematoda Cnidaria and Mollusca Echinodermata and Chordata 2. Charles a Biology student in California has found at the beach an animal he cannot name. What are some of the questions that he should ask to help determine the phylum of the animal? Based on the data that you recorded during this lab do you see a relationship between symmetry, cephalization, and number of germ layers? Can you tell what germ layer appears last? Name three characteristics or features in the phyla studied that you could tell are ancestral or primitive and three that you may call advance? Explain further?
