A hydro skeleton is not bony, but rather is a cavity filled by pressurized fluid.The noncompressible fluid of the body cavity can function as a ~ against which muscle s can work.ypertension High blood pressure; blood pressure consistently above 140/90. hydrostatic skeleton. (hy-droh-stat-ik). A skeletal system composed of fluid held under pressure in a closed body compartment; the main skeleton of most cnidarians, flatworms, nematodes, and annelids. hydroxyl group ...
