Triploblastic means having three germ layers (ectoderm, mesoderm, endoderm). Bilaterally symmetrical means the body can be divided into two mirror halves. Acoelomate means lacking a true body cavity. Tapeworms (Phylum Platyhelminthes) fit all these descriptions. Hydra is diploblastic, starfish is radially symmetrical (adult), and earthworm is coelomate.
