The hydrostatic skeleton of a jellyfish is made up of various muscles that act as pumps which increase fluid pressure in the tubes that the skeleton is made of. As the pressure goes up, the pseudo skeleton hardens until it becomes rigid from fluid pressure.

Flatworms do not possess either an exoskeleton or an endoskeleton. Instead, they have a soft, flexible body covered by a protective layer called the tegument.

Flatworms rely on a hydrostatic skeleton formed by the fluid within their bodies for structural support.
