Answer:

  • They show bilateral body symmetry.
  • Their body is dorsoventrally flattened like a ribbon. So they are also called flatworms.
  • Most of them are parasitic, only a few are free living.
  • They are mostly hermaphrodites.
  • There are three embryonic layers of cells in their body. So, they are triploblastic.
  • The body does not have any pore or cavity.
