  1. Phylum:Cnidaria By: Kevin Cindy Mercedes and Franklin

  3. Body Segmentation The Phylum Cnidaria doesn't have body segmentation because they don't have segments Unlike worms that have segments

  4. Type of Skeleton There is no skeleton

  5. Type of digestive tract They use a Gastrovascular cavity

  6. Type of nervous system The nervous system is the nerve net

  7. Method of respiration They do breathe because jellyfish have 2 layer's on it and since the ocean has more oxygen in it it goes through the jellyfish so it stays balanced
