It has always been a debate. Mesenchymal musculature in the middle tissue layer of ctenophores has invited speculation that they are triploblastic.
Yes, a protostome is, and so is a deuterostome. Neither are diploblastic. This is mainly because of the developement of the coelem or body cavity. Just remember, both protosome and deuterostome require a three germ layer (that is a triploblastic cell) - ALWAYS
The scientific name of comb jelly is Ctenophora.
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.
Al jellyfish are diploblastic; having two dermal lawyers. Ectoderm and endoderm.
jellyfish
No, triploblastic.
diploblastic have two body wall ectoderm and endoderm
Triploblastic organisms have three germ layers (ectoderm, mesoderm, endoderm), allowing for the development of more complex structures like organs and tissues, while diploblastic organisms have two germ layers (ectoderm, endoderm). Triploblastic organisms are usually more advanced and have greater complexity in their body structure compared to diploblastic organisms.

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 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).
No, roundworms are not diploblastic; they are triploblastic. They possess three germ layers: ectoderm, mesoderm, and endoderm. This classification places them in the group of animals known as triploblastic organisms, which also includes most other animals, including vertebrates and many invertebrates. Diploblastic organisms, like cnidarians, have only two germ layers: ectoderm and endoderm.
Gastrulation
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.
Yes, platyhelminthes are diploblastic, meaning they have two primary germ layers during embryonic development: the ectoderm and endoderm. They lack a mesoderm layer.
A tapeworm is triploblastic, meaning it develops from three embryonic germ layers: ectoderm, mesoderm, and endoderm. This classification is typical of more complex organisms, including members of the phylum Platyhelminthes, to which tapeworms belong. In contrast, diploblastic organisms have only two germ layers.
Diploblastic organisms have two primary germ layers (ectoderm and endoderm), found in cnidarians and ctenophores. Triploblastic organisms have three primary germ layers (ectoderm, mesoderm, and endoderm) and are found in most other animal groups. The presence of a mesoderm layer in triploblastic organisms allows for more complex organ systems and structures.
