Chapter 17, Problem 1FFT
Summary Introduction
To describe: The morphological features that need to be changed to produce an unsegmented body cavity.
Introduction: Annelids are classified based on their characters, morphology, anatomy, and most importantly their phylogeny. Some examples are marine bristle worms, leeches, earthworms.
Summary Introduction
To describe: The evidence of the transition between segmented and unsegmented body coelom in annelids.
Introduction: Phylum Annelida is a large phylum consisting of more than 22000 species. The members of these phylum are invertebrates having triploblastic cleavage.

Review the extent of segmentation in Polychaetes, Leeches, Siboglinids, Echicrans, and Sipunculans. Which morphological features must change to produce an unsegmented body cavity? Is there evidence of transitional stages for these features?
compare cnidarians to sponges and to the clade containing flatworms, mollusks, and annelids. What features are similar among these groups? What features are different?
Define adaptation. How could you use a comparative approach to test whether mesoglea within a scyphozoan medusa was an adaptation for buoyancy? How could you use a different criterion to test whether the eyes of cubozoans were adaptive? Where would a comparative approach prove a better way to assess the adaptive values of a tegument in internal parasites: in tapeworms or nematodes? Why?
