Mesoglea is the translucent, inert, jelly-like substance that makes up most of the bodies of jellyfish, comb jellies and certain primitive sea creatures in the phyla Cnidaria and Ctenophora. It acts as the creatures' structural support in water, as they lack bones or cartilage, endo- or exoskeletons, or similar means of support. Because mesoglea is a gel with such a high water content, these creatures tend to collapse on land.
