Many animals undergo molting as a means of shedding their outer layer—feathers, hair, skin, or exoskeleton—so they can grow bigger or prepare for their next life stage. “It's a critical event in the life cycle of an organism,” says Donald Mykles, a biologist at Colorado State University.

Why some animals undergo molting shedding?
In arthropods, such as insects, arachnids and crustaceans, moulting is the shedding of the exoskeleton (which is often called its shell), typically to let the organism grow. ... The old exoskeleton is called an exuviae. While moulting, insects can't breathe.
What is the purpose of moulting?
Molting entails synthesis of the new skin and shedding of the old, and it is important for the growth and maturation of many animals.
What is molting and why does it occur?
Molting. The molting process is triggered by hormones released when an insect's growth reaches the physical limits of its exoskeleton. Each molt represents the end of one growth stage (instar) and the beginning of another (Figure 1).
What kind of animals molt?
Many organisms such as spiders, insects, birds, snakes, and crustaceans molt. The molting process is unique for each of these animals that shed.
Do crabs eat their molt?
Crabs that are molting are not concerned with food and digestion. ... Once they complete shedding, they eat their exoskeleton and, because all nutrients from the exoskeleton are absorbed, the a crab eating its exoskeleton does not produce the amount of feces that an un-molting crab produces.
Why do chickens molt?
Molt is driven by season and usually occurs in the fall when the hours of sunlight decrease. For our birds, fall means it's time to prepare for winter, which requires quality feathers. That's why hens take a vacation from laying eggs and redirect their energy to feather regrowth.
Do humans molt?
But humans do molt. We shed hairs and skin cells. ... "Molting" means the periodic shedding of feathers, hairs, horns, nails, shells, and skins - any outer layer. Molt is from the Latin mutare meaning "to change".
What is cockroach molting?
A cockroach has to moult as its hard outer covering, known as the exoskeleton, doesn't grow meaning it has to periodically develop a new covering underneath the old. Caroline explained: “When it is time to moult, the old exoskeleton splits from the head right down the thorax before the cockroach crawls out.
Is the molting hormone?
The steroid hormone ecdysone, secreted by specific endocrine centres and circulated in the blood, is the direct initiator of molting. The actual timing of a molt, however, is regulated by other hormones and commonly by environmental factors. The interval between molts is called an instar.
Does molting hurt?
Avoid Stress & Handling
As humans we want to hug away the hurt, but not only is handling during molting stressful, it is also painful. The new feather shafts (pin feathers) are very sensitive and can be painful when touched. If the pin feathers are damaged, they can bleed profusely.
What is Rabbit molting?
As all rabbit owners are aware, rabbits moult (often referred to as shedding) regularly. Initially when rabbits are young, their baby coat is replaced at around 5 months by a transitional coat. After this, the rabbit's adult coat will develop and from here on, rabbits generally moult twice a year (Spring and Autumn).
Do dogs molt?
What do we mean by moulting? Dog moulting is a natural part of life for our dogs' wilder cousins. As they live outside, a thicker winter coat is essential to survival in the colder months, while a lighter summer coat helps to them cool enough to forage and hunt when temperatures rise.
Do snakes molt?
A regularly recurrent event during the activity period of all snakes is the shedding, or molting, of the skin. ... At this point, the snake's eyes become a milky blue, an indication of a physiological loosening of the skin that forms the eye cap.
Do worms molt?
Four times in its life, a growing nematode worm flips on its side and writhes around to shed its exoskeleton, or cuticle. During each molt, a worm casts aside its cuticle and synthesizes a new protective shell, its primary defense against a harsh environment.
Do all crabs molt?
Molting: How Crabs Grow
Crabs (and other crustaceans) cannot grow in a linear fashion like most animals. Because they have a hard outer shell (the exoskeleton) that does not grow, they must shed their shells, a process called molting. Just as we outgrow our clothing, crabs outgrow their shells.
