Chapter 33, Problem 9IQ
Summary Introduction
To compare: The given features of crustaceans and insects and contrast them.
Introduction: Animal phylogeny is the rapidly changing field for the biologists. The members of the animal kingdom are incredibly diverse. However, there are certain common features that differentiate them from other organisms of the kingdom. Arthropods are considered as the most biologically successful animal group. The arthropods are diverse group of animals and they cover a greater range of habitats than the other animal group members. According to various molecular data, eye structure, and genome analysis, the pancrustaceans are divided into two groups, namely crustaceans and hexapods (insects).

List the major features that distinguish the crustaceans,insects, and arachnids.
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.
