Animals molt to rid themselves of old skin cells and make room for their new skin cells. Like all other cells in the body, an animal's skin cells wear out and die over time. This means that animals have to produce new cells to take the place of those who've died.

What is molting Why is molting necessary to some animals?
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.
What is molting and why is it necessary?
Moulting is necessary as the arthropod exoskeleton is inflexible and so, to grow larger, arthropods must moult. Moulting is a critical but vulnerable time for arthropods. Their existing cuticle weakens at specific points and by taking in water or air the animal splits its old exoskeleton.
Why is arthropods molting necessary?
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.
What are the advantages of molting?
it is cheaper to carry a bird through a moult than to buy replacement pullets. fewer replacement pullets may be needed, and buying can often be deferred, which can mean a saving of money, time and transport. moulted birds are hardier, and not as prone to disease.
What is the function of molting?
Molting is the shedding of the exoskeleton (cuticle) of the previous life stage. Without molting, an insect cannot grow. Once a new cuticle is fully formed, an insect engages in species-specific stereotyped patterns of movements (molting behaviors) that liberate it from the cuticle of the previous stage.
Why does molting occur?
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 is animal molting?
molt, also spelled Moult, biological process of molting (moulting)—i.e., the shedding or casting off of an outer layer or covering and the formation of its replacement. Molting, which is regulated by hormones, occurs throughout the animal kingdom.
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.
Why is molting of the exoskeleton necessary How is it accomplished give the stages involved?
Because the exoskeleton is hard and rigid, an arthropod cannot grow unless it sheds its old exoskeleton and secretes a new one. This process is called molting. Arthropod growth is limited to molting, so growth happens in steps rather than continuously. The stages between moltings are called instars.
Why do reptiles shed?
All reptiles shed their skin as they grow, and they continue to shed periodically through out life. Improper or incomplete shedding may occur because of mites, incorrect humidity or handling, malnutrition, dermatitis or trauma. ... Lizards too shed their skin in pieces and some lizards eat their sloughed skin.
Why do insects need to molt?
When an insect gets too big for its exoskeleton, it sheds it. This process—known as molting—might sound matter-of-fact, but it's not. Insects stop eating, many lie still, and they become more vulnerable to predators. ... Larvae can also absorb some oxygen through their soft exoskeleton.
Do snakes shed or molt?
A regularly recurrent event during the activity period of all snakes is the shedding, or molting, of the skin. Dormant individuals do not shed, but quite often this is one of the first events to take place after the end of dormancy.
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".
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.
