Q. How are animals classified according to the germ layers present in their embryonic development?

Cnidarians are diploblastic, that is they present only ectoderm and endoderm. With the exception of poriferans all remaining animals are triploblastic. Poriferans do not present differentiated tissue organization and so they don't classify regarding germ layers although sometimes they are mentioned as diploblastic.
