Hydra are diploblastic - something from the hydra family possesses only an ectoderm and endoderm, around its body cavity (stomach). If it was triploblastic, there would be organs developing from the central layer.
DIPLOBLASTICHave 2 body layers (ectoderm and endoderm)Their body cells are in contact with the environment and use diffusion to get their requirements and get rid of wasteHave a tissue layer of organisation with specialized tissues to perform specific functions (they have no organs or organ systems)TRIPLOBLASTICHave 3 body layers (ectoderm, mesoderm and endoderm)The mesoderm creates a space for organs to develop.The greater number of layers and greater complexity of the organisms means that it needs to develop organs and organ systems to provide what it require and get rid of waste.

"Poriferans" is the scientific term for sponges, members of the animal phylum Porifera, which means "pore-bearer" in Greek. Sponges are the simplest animals known. Unlike all other animal phyla, which have two or three-layered body plans (diploblastic or triploblastic), sponges have only a single body layer (monoblastic), and no true tissues. They have no appendages and no ability to make any movements, lacking muscle tissues. Sponges are exclusively aquatic.
Yes, platyhelminthes are diploblastic, meaning they have two primary germ layers during embryonic development: the ectoderm and endoderm. They lack a mesoderm layer.
diploblastic have two body wall ectoderm and endoderm
Al jellyfish are diploblastic; having two dermal lawyers. Ectoderm and endoderm.
No, triploblastic.
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.

The scientific name for flatworm is Platyhelminthes.
Cnidaria and Ctenophora are the two phyla that are diploblastic, meaning they have two germ layers during embryonic development – the ectoderm and endoderm.
