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?
Al jellyfish are diploblastic; having two dermal lawyers. Ectoderm and endoderm.
What animal does not have nerve or muscle tissue and is neither diploblastic or triploblastci?
jellyfish
What are examples of diploblastic animals?
Al jellyfish are diploblastic; having two dermal lawyers. Ectoderm and endoderm.
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 the examples of diploblastic organism?
Diploblastic organisms are those with two primary germ layers: the ectoderm and endoderm. Examples include cnidarians, such as jellyfish, corals, and sea anemones, as well as comb jellies (ctenophores). These organisms typically exhibit radial symmetry and lack true tissues and organs found in more complex triploblastic organisms.
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.
What substance allows the moon jelly to float in the water?
It is called the mesoglea, or the middle layer between the outer ectodermal tissue and the inner gastrodermal tissue. Jellyfish are considered diploblastic, or two tissued. A secretional, gelatinous substance makes up the mesoglea and it provides the jellyfish with several benefits. Since it is less dense than the cellular parts of the organism, it allows the jellyfish to have neutral buoyancy. It also gives the bell some rigidity, and the ability to spring back after muscular contractions.
