Detailed explanation-1: -A jellyfish skeleton is made up of fluid-filled cavities surrounded by air. The process of shedding an outgrown exoskeleton. A connective tissue that is more flexible than bone and that protects the ends of bones and keeps them from rubbing together.

Detailed explanation-2: -Jellyfish have hydrostatic skeletons Rather than a skeleton made up of bones, jellyfish have bells containing fluid and circular muscles.

Detailed explanation-3: -A hydrostatic skeleton is a skeleton formed by a fluid-filled compartment within the body, called the coelom. The organs of the coelom are supported by the aqueous fluid, which also resists external compression.

Detailed explanation-4: -This type of skeletal system is found in soft-bodied animals such as sea anemones, earthworms, Cnidaria, and other invertebrates (Figure 38.1.

Detailed explanation-5: -Hydrostatic Skeletons. A hydrostatic skeleton is a structure found in many cold-blooded and soft-bodied organisms. It consists of a fluid-filled cavity, which is surrounded by muscles. The cavity is called a coelom and in some animals, this cavity is filled with a blood-like substance called haemocoel.
