Jellyfish have what is called a hydrostatic skeletal system. This means that it is not actually hard. It is more similar to a balloon filled with water. It allows the jellyfish to move in the water as well as allowing its body shape to change with the movement of the ocean and with the jellyfish's own movement without causing injury to the animal. This kind of flexibility is required for such a delicate animal to survive. It's really an amazing system. When the jellyfish contracts the muscles surrounding the pouch (its hydrostatic skeleton) it causes movement.
Jellyfish are not the only animals with this kind of skeleton. For example, earthworms also have a hydrostatic skeleton. That is why they can be long and skinny one moment, and short and fat the next.
