  5. Flatworms (Platyhelminthes) • Least complex of the worms • Parasitic: tape worm (scolex, proglottid), fluke (snail host) • free-living: planaria (flame cells, regeneration) • Roundworms (Nematoda) • 2 body openings • Ascaris, trichinella, pin worm • Segmented worms • Setae, segmentation with own muscles, specialization, nerve cords • Closed circ system • Oligochaeta, Polychaeta, Hirudinae Chapter 26 & 27: The worms
