Answer:
hydrozoa
Explanation:
Porifera is neither triploblastic nor diploblastic since Porifera contains the cellular level of organization. Diploblastic and Triploblastic animals are those which have a tissue level of organization.
Recent interpretations of the medusary nodule (the structure that, from a polyp, gives rise to a medusa by a special type of budding) suggest that the Hydrozoa are triploblastic.
The mesoderm allows them to develop true organs. Groups of diploblastic animals alive today include jellyfish, corals, sea anemones and comb jellies. hence anthozoa is diploblastic
Scyphozoans exhibit the main characteristics of cnidarians. They have radial symmetry and are diploblastic, meaning that their body wall consists of the outer epidermis (ectoderm) and the inner gastrodermis (endoderm), which are separated by mesoglea.
