A starfish has a hydrostatic skeleton, which means it relies on the pressure of its internal fluids to maintain its shape and support its body. This type of skeleton allows for flexibility and movement, enabling the starfish to navigate its environment. In contrast, an exoskeleton is a rigid external structure found in organisms like insects and crustaceans, which is not applicable to starfish.
Some animals have that a hydrostatic skeleton include jellyfish and earthworms. Additional examples include sea urchins and starfish. As a result of their flexibility, hydrostatic skeletons are particularly useful for locomotion.

A hydro test is a test used to determine the strength and integrity of a pressure vessel or piping system by filling it with water and pressurizing it to a specified level. Hydrostatic refers to the resulting pressure that is exerted by a fluid at rest due to gravity.

Exoskeletons, hydro-skeletons, and internal skeletons are all structural systems that provide support and shape to organisms. Exoskeletons, like those found in insects and crustaceans, are rigid outer structures made of chitin or calcium carbonate. Hydro-skeletons, seen in organisms like jellyfish, rely on fluid pressure within a cavity to maintain shape and support movement. Internal skeletons, or endoskeletons, such as those in vertebrates, are internal structures made of bone or cartilage that provide support while allowing for growth and flexibility.
