The polyps belong to a group of animals known as Cnidaria, which also includes sea anemones and Jellyfish. Unlike sea anemones, coral polyps secrete hard arbonate exoskeletons which support and protect their bodies.
Arthropods such as crustaceans, meanwhile, have additional calcium carbonate in their exoskeletons for extra armour plating. As well as supporting and protecting the creature, an exoskeleton also creates a watertight barrier that prevents the animal from drying out.

Robotic exoskeletons are powered devices that attach around and to a human or animal body and contain actuators that deliver mechanical power to aid movement. Some robotic exoskeletons facilitate upper limb movements such as reaching, grasping, or lifting an object.
Exoskeletons first developed in the aquatic environment in ancient arthropods. Animals with this type of skeleton include crustaceans like crabs and lobsters. Figure 6.2: Crustaceans, such as this crab, developed a protective exoskeleton.
Examples of animals with exoskeletons include insects such as grasshoppers and cockroaches, and crustaceans such as crabs and lobsters, as well as the shells of certain sponges and the various groups of shelled molluscs, including those of snails, clams, tusk shells, chitons and nautilus.
The exoskeleton found on animals like clams is made of calcium carbonate, while the exoskeleton found on insects is partially made of chitin, a kind of polysaccharide. A polysaccharide is a chain.
A hard exoskeleton: The exoskeleton of an arthropod is made of a strong polysaccharide called chitin. This hard shell protects the animal, retains moisture, and sometimes even plays a role in reproduction. Compound eyes: Compound eyes allow arthropods to take in their environment in a variety of ways. Arthropods can see through a very wide lens.
Even the largest living animal with an internal skeleton (the blue whale) and the largest without a skeleton (e.g. the lion’s mane jellyfish) are aquatic, so the support provided by water helps ALL creatures reach larger sizes, not just those with exoskeletons.
