hydrostatic skeleton Fluid-?lled closed chambers that give support and shape to the body in organisms such as jelly?sh and earthworms. No to be confused with the water-vascular system of echinoderms.
A skeletal system composed of fluid held under pressure in a closed body compartment; the main skeleton of most cnidarians, flatworms, nematodes, and annelids.

hydrostatic skeleton a water-based skeleton present in many animals (such as the earthworm) that lack structures, such as bone, for muscles to pull against.
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 skeleton . A mass of fluid or plastic parenchyma enclosed within a muscular wall to provide the support necessary for antagonistic muscle action; for example, ...
A hydroskeleton, also called hydrostatic skeleton, occurs in many soft-bodied animals, such as earthworms. A hydroskeleton is not bony, but rather is a cavity filled by pressurized fluid.
The noncompressible fluid of the body cavity can function as a hydrostatic skeleton against which muscles can work.
The presence of a cavity enables the internal organs to grow and move independently of the outer body wall.

The skeleton may be an endoskeleton, an exoskeleton or a hydrostatic skeleton. The support system will be adapted to methods of locomotion for a particular animal (e.g, flying, swimming, climbing, and walking).
Our own skeleton so whether youâre insect and you wear your skeleton on the outside or youâre jelly fish and you use water thatâs on the inside of you as a hydrostatic skeleton.
