Do sponges have hydrostatic skeletons?
Sponges do not have hydrostatic skeletons. Instead, they possess a simple body structure supported by a matrix called mesohyl, which contains various cells and skeletal elements like spicules and collagen fibers. This structure provides support and helps maintain the sponge’s shape, but it lacks the fluid-filled cavities characteristic of hydrostatic skeletons found in other animals. Thus, sponges rely on a different mechanism for structural support.
