Flatworms or Platyhelmithes are billaterally symmetrical. in short, their left and right sides are mirror images of each other. this also implies that they have distinct top. Plus, bottom surfaces and distinct head and tail ends.
Because they do not have internal body cavities, for over a century Flatworms were regarded as a primitive stage in the evolution of bilaterians (animals with bilateral symmetry and hence with distinct front and rear ends).
