They are triploblastic because they are apart of the phyla Echinodermata. If you look at the animal phylogenetic tree you can see that starfish are apart of the triploblasts. The difference between diploblastic and triploblastic is that diploblastic have two germ layers during development which are the ectoderm and endoderm. Triploblastic animals (like starfish, and humans) have three germ layers which are the ectoderm (outside), mesoderm (middle) and endoderm (inside).

Al jellyfish are diploblastic; having two dermal lawyers. Ectoderm and endoderm.

Cnidaria are Diploblastic, having two main body layers. They also have a Mesoderm, but this is simply a collection of nerves, creating a nerve net.
Diploblastic organisms consist of : Ectoderm and Endoderm
diploblastic have two body wall ectoderm and endoderm
No, triploblastic.
Triploblastic have three germinal layers and Diploblastic have two germinal layers
Porifera (sponges) have no specialized cells. To be diploblastic animal phyla must have a minimum of two cell layers referred to as ectoderm and endoderm. The absence of these cell types make it impossible for any members of porifera to be diploblastic.
Cnidaria and Ctenophora are the two phyla that are diploblastic, meaning they have two germ layers during embryonic development – the ectoderm and endoderm.
They are animals having two germinal layers in the embryo, the outer ectoderm and the inner endoterm .Example of diploblastic animals are porifera and cnidaria.
Diploblastic animals usually develop from the blastula. They were initially grouped in the phylum Coelenterate. They were then removed and grouped in a different phyla when the differences were discovered.
