Cnidarians secrete mesoglea - which is a jelly-like substance that separates the ectoderm and endoderm.
mesoglea
The "jelly layer" of jellyfish (and other cnidarians) is called the "mesoglea." The mesoglea is a gelatinous, mostly acellular layer composed of fibrous proteins, such as collagen. The mesoglea often have some muscle fiber bundles and nerves to maintain the mesoglea's form, as well as some amoebocyte cells to consume debris and invading pathogens. The mesoglea serves as an internal skeleton to help the cnidarian retain its form after it relaxes from contracting.
I had that same question too... its the Mesoglea
mesoglea.
The gel-like substance located between the endoderm and ectoderm is called the mesoglea. It provides structure and support to the body wall of various organisms such as cnidarians like jellyfish.
The ectoderm is located on the outside layer of animal. It hold either the mesoglea or the mesoderm in.
In aquatic animals like cnidarians : mesogles helps in maintenance of buoyancy and transparency
No. The mesoglea -- the jelly -- is at most 5 percent of the jellyfish.

It's the jelly-like substance that is found between the two layers of cells in a cnidarian. The mesogea is not in all cnidarians though
The term for the gelatinous matrix in which all of the cells of a sponge are embedded is called mesohyl or mesoglea.
