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).

What are examples of diploblastic animals?

Are cnidaria triploblastic?
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.
What are Difference beteewn diploblastic and triploblastic organization?
diploblastic have two body wall ectoderm and endoderm
Is a flatworm diploblastic?
No, triploblastic.
What members of porifera are diploblastic?
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.
Which phyla are diploblastic?
Cnidaria and Ctenophora are the two phyla that are diploblastic, meaning they have two germ layers during embryonic development – the ectoderm and endoderm.
What is the meaning of diploblastic animals?
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.
What are the two tissues layers of diploblastic organisms?
The two tissue layers of diploblastic organisms are the ectoderm and endoderm. Ectoderm is the outermost layer responsible for covering and protection, while endoderm is the innermost layer involved in digestion and nutrient absorption.
Are sponges diploblastic?
Yes. they have two germ layers - or a two - layerd body wall. The epidermis and gastrodermis. Actually sponges lack true tissues and are therefore not diploblastic.
What is the group in which diploblastic animals found?
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.
