������ƵMarch Madness: Non-Bilaterian Division

While bilaterian animals have a distinct front, back, top, and bottom, non-bilaterian organisms lack that symmetry. Non-bilaterian animals include sponges, jellyfish, corals, comb jellies, sea anemones, and placazoa (simple, free-floating multicellular marine organisms). This group split from bilaterians early in animal evolution.
