Students will understand the structure and function of phylum Porifera and phylum Cnidaria and how each adapts to their environments.

- Phyla Porifera and Cnidaria are two of the most primitive of animal phyla. They distinguish themselves from other metazoans by their lack of bilateral symmetry. Each phylum has its own anatomy, physiology, and unique role in aquatic ecosystems.
