Choanoflagellates ANIMALIA Porifera sponges) Radial symmetry Ctenophora (comb jellies) Radial symmetry aria (jellyfish, corals LOPHOTROCHOZOA -Rotifera Diploblasty (rotifers) Loss of coelom Platyhelminthes (flatworms) Segmentation Annelida segmented worms) Mollusca (snails, clams, squid) ECDYSOZOA -Nematoda Arthropoda Bilateral symmetry Triploblasty Cephalization Coelom? Segmentation (insects, spiders, DEUTEROSTOMES Radial symmetry Echinodermata in adults)(sea stars, sand dollars) -Chordata tes) A nematode is a [k], a human is a [vl, while a sponge is a [z] b. protostome c. none of these d. diploblast e. unicellular organism 2.
