| 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.
