Summary Introduction
To review:
The given blank space in the statement, “for each of the following distinctive structures, name the animal group in which it is found:
Mantle: ______________
Cnidocyte: __________
Water-vascular system: _____________
Paired, jointed appendages: ___________.”
Introduction:
Each and every animal group has unique structures that distinguish them from others. They obtain energy by consuming other animals. Their cell is not covered by the cell wall and is multicellular. They are motile and reproduce sexually. They are generally able to respond to the stimuli.

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.
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.
