  8. Varies but the most advanced is the squid which is about as intelligent as a domestic cat Cephalization

  9. Coelom is a fluid filled cavity that develops with the mesoderm • They possess a coelom that functions as a hydrostatic skeleton Coelom

  10. They have a two ended digestive tract with mouth and anus • Releases wastes into the water Digestive Tract

  11. They have bilateral symmetry Symmetry
