eumetazoa diploblastic definition - EAS
Radially symmetric animalsAnimals with a more complex structure than a sponge (eumetazoans) however produce two or three germ layers. Radially symmetric animals are diploblastic. They produce only two germ layers: endoderm and the ectoderm.Ectoderm
Ectoderm is one of the three primary germ layers in the very early embryo. The other two layers are the mesoderm and endoderm, with the ectoderm as the most exterior layer. It emerges and originates from the outer layer of germ cells. The word ectoderm comes from the Greek ektos meaning "outside", and derma, meaning "skin."

Eumetazoa Subkingdom - QS Study
https://qsstudy.com/eumetazoa-subkingdomEumetazoa is a major division of the animal kingdom comprising all multicellular forms except the sponges. It is a large group including most of the multicellular animals. Hence it is subdivided further into two groups. Diploblastic animals – having ectoderm and endoderm as two layers in the body wall. Ex: Coelenterata.
