Worms use a hydrostatic skeleton to generate movement. How do they do this? Select one: The term hydrostatic simply refers to moist environment. They generate movement just as arthropods do. Their bones are filled with water, which provides the weight of the skeleton. The change in body structure is caused by contraction of muscles compressing the watery body fluid. The muscles contain water vacuoles, which, when filled, provide a rigid internal structure.
