1. This is why hydrostatic skeletons are common in marine life. 2. Other vertebrates sometimes utilize a modified hydrostatic skeleton called a muscular hydrostat. 3. This allows for more precise movement compared to a typical hydrostatic skeleton . 4. Many have fluid-filled, hydrostatic skeletons , like jellyfish or worms. 5. Helically reinforced hydrostatic skeleton structure is typical for flexible structures as in soft-bodied animals. 6. It performs its hydraulic movement without fluid in a separate compartment, as in a hydrostatic skeleton . 7. Connective fibers, often collagenous, are arranged in a helical shape within the wall of the hydrostatic skeleton . 8. Helical muscles may be present, which can create torsion, an ability that is restricted in hydrostatic skeletons . 9. A muscular hydrostat, like a hydrostatic skeleton , relies on the fact that water is effectively physiological pressures. 10. Terrestrial organisms that have hydrostatic skeletons generally have a lack of strength because they are not in a fluid environment.
