1A. Phylum Platyhelminthes (flatworms).
Describe 3 characteristics of flatworm bodies that both differ from
cnidarians and enable them to more actively hunt
their prey.
1B. Phylum Mollusca. Describe three
evolutionary changes that transformed the basic molluscan body plan
(similar to abalones) into a squid’s highly effective swimming and
hunting body (~3 sentences.) HINT: Consider changes to the shell,
foot (see section on nautilus jet propulsion), mantle and nervous
system.
1C. Phylum Annelida. Describe three
behaviors of you learned about aquatic
annelids.
