Detailed explanation-1: -The Arthropoda use chitin and various proteins as basic materials of their cuticle which is forming their exoskeletons.

Detailed explanation-2: -Arthropods are covered with a tough, resilient integument or exoskeleton of chitin. Generally the exoskeleton will have thickened areas in which the chitin is reinforced or stiffened by materials such as minerals or hardened proteins. This happens in parts of the body where there is a need for rigidity or elasticity.

Detailed explanation-3: -All arthropods have a hard exoskeleton made of chiton, a type of protein. This shell provides protection for the animals, and gives support for the attachment of the arthropod’s muscles. Although arthropods grow, their exoskeletons do not grow with them.

Detailed explanation-4: -Arthropod Armor The bodies of arthropods are supported, not by internal bones, but by a hardened exoskeleton made of chitin, a substance produced by many non-arthropods as well.

Detailed explanation-5: -Arthropods are covered with a tough, resilient integument or exoskeleton of chitin. Generally the exoskeleton will have thickened areas in which the chitin is reinforced or stiffened by materials such as minerals or hardened proteins.
