Quizplus · Accepted Answer

The cuticle of arthropods is an example of an exoskeleton, not a hydrostatic skeleton. Hydrostatic skeletons are fluid-filled cavities that are surrounded by muscles and can change shape by muscle contractions. Acoelomates have a gastrovascular cavity that acts as a hydrostatic skeleton, nemerteans have a rhynchocoel, nematodes have a pseudocoelom, and molluscs have a hemocoel.
