The Integumentary system:
The integumentary system consist of 4 layers; namely epicuticle, procuticle, epidermis and basement membrane. The layer that is responsible for locking and storing water is the outermost layer, the namely epucticle. The next layer, the procuticle is there to support and give strength to the exoskeleton. The last layer, the epidermis is responsible to secrete the procuticle.
The main purpose for the integumentary system is to give a structure to the animal for support. This system also helps protect everything that is on the inside of the organism and protects all of its organs. The exoskeleton of these organism is composed of many layers of protein and a tough polysaccharide.
