Embryonic progress

How are animals classified in relation to the germ layers present in their embryonic progress?

E

Expert

Verified

Cnidarians are diploblastic, i.e. they present simply endoderm and ectoderm. With the exemption of poriferans, all left over animals are triploblastic. Poriferans don’t present differentiated tissue organization and hence they don’t classify regarding germ layers (though sometimes they are mentioned as diploblastic).
