Question

what is hydrostatic sekeleton give example ​

Answer 1

Answer:

Hydrostatic skeletons are very common in invertebrates. A common example is the earthworm. Also, hydrostatic nature is common in marine life such as jelly fish, starfish, and sea anemones. Earthworms have rings of muscles that are filled with fluid, making their entire body hydrostatic.

For example, earthworms move by waves of muscular contractions of the skeletal muscle of the body wall hydrostatic skeleton, called peristalsis, which alternately shorten and lengthen the body.
