We just learned about the Jellyfish - Epidermis.
Another part of the jellyfish body is the Mesoglea.
Underneath the bell part of the jellyfish is an open area that is made up of water and some other gooey stuff called collagen.
It's almost like a balloon full of jelly that helps the jellyfish keep it's shape in the water.
