• Subkingdom Eumetazoa (all the other phyla) - The
  Eumetazoa consist of all the other animal phyla.
• The Radiata-Bilateria Split
• Branch Radiata
• The phyla in this branch have radial symmetry.
• These animals have an oral (top) and aboral
  (bottom) side, but no front, back, left or right
  sides.
• This branch includes the phylum Cnidaria, (the
  jellyfish, sea anemonies, and corals).

• Branch Bilateria
• The phyla in this branch have bilateral symmetry.
  
• Bilaterally symmetrical animals have dorsal
  (top), ventral (bottom), anterior (head),
  posterior (tail), left and right body surfaces.
  These animals exhibit cephalization (an
  evolutionary trend toward concentration of
  sensory structures at the anterior end). This
  branch includes all other animal phyla.
• Care must be taken when assigning an animal to an
  evolutionary line. Some such as the Phylum
  Echinodermata, show secondary radial symmetry
  which evolved as an adaptation to their lifestyle
