Hydrostatic skeleton

Hydrostatic skeletons consist of fluid-filled closed chambers. Internal pressures generated by muscle contractions cause movement as well as maintain the shape of the animals, such as the sea anemone and worms.

Hydrostatic skeletons are similar to a water-filled balloon. Located internally in cnidarians (coral, jellyfish, etc.) and annelids (leeches), among others, these animals can move by contracting the muscles surrounding the fluid-filled pouch, ...

Vertebrates have a skeleton of bone or cartilage; arthropods have one made of chitin; while many other invertebrates use a hydrostatic skeleton, which is merely an incompressible fluid-filled region of their body.

It can take the form of an internal bony skeleton as in vertebrates, an external calcareous or chitinous exoskeleton as in arthropods, a hydrostatic skeleton as in jellyfish , or that of a subcellular system of support.
