Detailed explanation-1: -In arthropod: The exoskeleton and molting. …in arthropods by molting, or ecdysis, the periodic shedding of the old exoskeleton. The underlying cells release enzymes that digest the base of the old exoskeleton (much of the endocuticle) and then secrete a new exoskeleton beneath the old one.

Detailed explanation-2: -Ecdysis is the process of shedding an external skeleton for the purpose of growth or change in shape. Ecdysis is also known as molting commonly seen in insects, snakes.

Detailed explanation-3: -All cuticular structures are shed at ecdysis, including the inner parts of the exoskeleton, which includes terminal linings of the alimentary tract and of the tracheae if they are present.

Detailed explanation-4: -This process is called moulting and involves the synthesis of a new cuticle underneath the old one, the digestion and resorption of most of the old cuticle, and finally the shedding of the old cuticle in a behavioural process designated as “ecdysis”1.

Detailed explanation-5: -Arthropods shed their exoskeletons as they grow, a process called ecdysis or moulting, and this behaviour is controlled by a set of hormones and small protein-like molecules called neuropeptides that allow communication between neurons.
