Diploblastic: Coelenterates, Ctenophores; Triploblastic: Platyhelminthes to Chordates
Explanation
Animals in which cells are arranged in two embryonic layers (ectoderm and endoderm) with mesoglea in between are diploblastic (e.g., Coelenterata, Ctenophora). Animals with a third layer (mesoderm) are triploblastic (Platyhelminthes to Chordates).
