Summary Introduction
To name: The body plan of two cnidarians.
Introduction: Phylum Cnidaria is one of the oldest lineages of Eumetazoans. They originated about 680 million years ago. The phylum Cnidaria includes corals, jellies, and hydras.

Create a body plan table (Insert → Add Table) for the following animal phyla: Porifera, Cnidaria, Platyhelminthes, Mollusca, Annelida, Nematoda, Arthropoda, Echinodermata, and Chordata. Describe each phylum by identifying the following body plan features. Use Lesson 12 (Chapter 32) and Lesson 13 (Chapter 33) as a guide.
1) Symmetry: Asymmetrical, Radial, or Bilateral
2) Tissue type: Parazoa, Eumetazoa (diploblastic), or Eumetazoa (triploblastic)
3) Body cavity (if triploblastic): Acoelomate, Psuedocoelomate, or Coelomate
4) Developmental mode (if Coelomate): Protostome or Dueuterostome
Note: Depending on the body plan, features 3 & 4 may not apply to specific phyla.
* Please answer 3) and 4) ONLY. Thank you.
