  16. INVERTEBRATE CHARACTERISTICS AND TRENDS • asexual  sexual reproduction • Assymmetry  radial  bilateral symmetry • No tissues  2 layers  3 tissue layers • no body cavity  pseudo body cavity  true body cavity • protostomes  deuterostomes • circulatory systems open: blood pumped into open cavity  closed: blood vessels form loop • nerve net  simple nervous system  cephalization • No segmentation  segmentation  segmentation with appendages
