Molting refers to the shedding of the outer skin, and as the organism grows, the outer skin does not grow with it. Instead, it disposes of it by molting, and an example would be a snake shedding its skin is called molting.
Shedding may include shedding or molting of body parts, and it can entail the peeling of diseased or non-diseased skin. The shedding of the skin is because of a loss of fluid through the shed skin. Skin shedding may begin in small areas, but it spreads to most of the body over time.
The skin is comprised of mainly protein, and the continual shedding of the skin can prevent the body from absorbing vital nutrients to sustain a healthy epidermis. Biologically, molting is the method in which an animal rids itself of part of its body either at specific periods of the year or at different stages in its life.
