"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.
Porifera is name of phylum and animals belonging to it are called poriferans.
diploblastic have two body wall ectoderm and endoderm
Al jellyfish are diploblastic; having two dermal lawyers. Ectoderm and endoderm.
Poriferans (sponges) lack many common characteristics of animals such as a head or a mouth. Typically poriferans do not have eyes, ears, as well as other sense organs. Poriferans do not possess major organs such as heart, stomach, muscles, or even a nervous system.

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.
Diploblasts are organisms that develop from two primary germ layers during embryonic development. These layers are the ectoderm (outer layer) and endoderm (inner layer), with no mesoderm present. Examples include cnidarians like jellyfish and coral.
Cnidaria and Ctenophora are the two phyla that are diploblastic, meaning they have two germ layers during embryonic development – the ectoderm and endoderm.
All poriferans and coelenterates live in water, most of them in sea water, but some in fresh water. Poriferans are bottom-dwellers. Coelenterates can be free-swimming, fixed to the bottom or live in colonies fixed to the bottom, depending on species and face of life.
