Editing Hydrostatic skeleton (section)

== Advantages and disadvantages ==
Organisms containing a hydrostatic skeleton have advantages and disadvantages. Their fluid shape allows them to move around easily while swimming and burrowing. They can fit through oddly shaped passages and hide themselves more effectively from predators. They are able to create a force when squeezing through rocks and create a “prying open” gesture. There is a lightweight, flexible component to them that allows this movement with very little muscle mass.<ref name=":2">{{Cite web|url=http://www.everythingmaths.co.za/science/lifesciences/grade-10/06-support-systems-in-animals/06-support-systems-in-animals-02.cnxmlplus|title=Everything Math's and Science |website=www.everythingmaths.co.za|access-date=2016-12-01}}</ref>

These organisms are also able to heal faster than organisms that contain hard skeletons. Healing in these organisms varies from creature to creature. However, if the cavity needs to be refilled, the “fluid” can easily be refilled if it is water or blood. If the fluid is some other type of liquid, it can take longer, but it is still faster than healing a bone. The common [[earthworm]] is also able to regrow damaged parts of its body.<ref name=":2" />

These organisms have some relatively simple pathways for circulation and respiration. Also, these organisms have a cushion to allow protection for internal organs from shock. However, it does not protect internal organs from external damage very effectively.<ref name=":2" />

Because the hydrostatic skeletons have limited ability for attachment of limbs, the organisms are relatively simple and do not have many abilities to grab or latch onto things. Organisms with complete hydrostatic skeletons need to be in an environment that allows them to re-fill themselves with their fluid that is necessary for survival. This is why hydrostatic skeletons are common in marine life. They have a large amount of access to the necessary elements for survival. Terrestrial organisms that have hydrostatic skeletons generally have a lack of strength because they are not in a fluid environment. If one were to expand its body too much, it would collapse under its own weight.<ref name=":2" />
