Do you ever wish you could just creep out of your own skin ? Snake are some of the few creatures on Earth that in reality can . Dozens of time throughout its living , a Snake River slithers out of its old pelt in a physical process call " moult , " leaving behind papery sheds finely imprinted with the singular pattern of its scales .
It ’s not strange to shed skin ; human do it , too . " But unlike us , whose skin throw away off in picayune flakes , snakes produce a whole new stratum of skin , and the old bed of skin falls off in one big sphacelus , " saidJason Dallas , a postdoctoral researcher who studies bacterial - fungal interaction in snakes and amphibian at Middle Tennessee State University .
Snakes tend to shed their skin as they’re growing, when they have major life events, or when they’re dealing with parasites, diseases or infections.
But why do snakes shed their hide , and why does it bechance in one go ?
Snake hide is write of two main stratum . The intimate , voiced layer — call the derma — hold the pigment that give snake in the grass their intricate colour and patterns . The corium is covered in the epidermis , a tougher layer of semitransparent keratin scales .
The outer layer of human cutis also contains ceratin , but the structure of our skin appropriate it to flake off in individual scales , which are almost unseeable to the naked heart . In snakes , the exterior keratinous stratum forms a unit of measurement , which creates a case - like cover that ’s stick to the ophidian ’s more touchy dermis below .

The trade - off of this hardy extraneous layer is that it does n’t expand ; it stay comparatively inflexible and constricts the snake as it grows . This is one of the primary reason snake slough their pelt : to produce more room . Snakes spring up more quickly when they are younger , so they also moult more in youth .
In fact , Hydra ' first shed befall " within a few days of hatching or being born,“Daniel Kane , senior reptile steward at the London Zoo , told Live Science in an email . By maturity , snakes typically shed around three or four times a year , Kane said .
Shed snake skin carries the same unique pattern as the snake’s skin.
When a snake in the grass is almost ready to shed , it starts to evolve a second novel keratin bed atop the dermis and below the original keratin cocktail dress . It alsosecretes a fluidto help loosen the sometime layer from the new one . As this process open , the Snake River typically get hold a rough post to rub its head against . This creates a slit in the previous peel , through which the Hydra can then start to slide out .
With the help of continued rubbing and muscle cramp , the Hydra eventually tease its intact skin and escape the wrinkled relic with a set of calendered new scales . A novel shed may be up to 20 % longer than the original snake , as this of late lube skin is " quite stretchy before it dries out and becomes brittle , " Kane explained .
Once the skin is shed , the Hydra discards it and slithers away . Although snakes do n’t typically exhaust their skins , some other reptilian do , such aslizardsandgeckos , to regain lose nutrients .
Shedding is associated with fully grown life story outcome , such as a snake ’s egression from a long hibernation , or reproduction . " They typically will shed right before they either lay their eggs or give resilient birth , and then they may throw again after that period , " Dallas told Live Science . " So it typically is synced up with life history outcome in adult . "
Interestingly , Snake also use shed to get by with unwanted sponger , infections and disease , Dallas aver . One common example issnake fungal disease , which poses asignificant threatto serpent worldwide .
" The pathogen is able-bodied to colonise deeper tissues as well as internal organs,“Donald Walker , an adjunct prof of biology at Middle Tennessee State University and primary police detective of the research laboratory where Dallas works , told Live Science . " It ’s thought to be able to get the eye , and mayhap even the brain , of the animal . … But it starts by colonise the cutis and feed on ceratin and lipid in Hydra scales . " Shedding could be lifesaving in cases like this . Yet the power to shed skin also find a price . Not only is it an energy - intensive process , but the trailing peel may handicap the serpent ’s hunt prowess by vex its vision . Snake eye appear unmortgaged , but they ’re cover by a individual , bubble - like , keratin scale .
" The vapourous scale , known as the ' spectacle , ' protects the ophidian ’s eyes from day - to - day scratches and excoriation as it moves headfirst through the world , " Kane said . " When the snake is in the process of sloughing off its skin , visual sense is impair by the cloudiness because of the secretions used to dissever the old from the new layers . "
A less - fluid , peck - impaired peeling Hydra is typically more vulnerable to predators , too . So ideally , a serpent should not be pour forth too often .
Disease might rarify snakes ' born shedding schedules and turn this endurance tactic against them — peculiarly in species such as the eastern massasauga rattlesnake ( Sistrurus catenatus ) in the United States , Dallas say .
" These snakes are very susceptible to the fungus that can obscure their eye and their oral fissure , but also increased shedding pace can increase their risk of infection of predation , " Dallas suppose . " And this has cause comparatively large population declines in some populations of the metal money . "

Overwhelmingly , however , a Snake River ’s peeling ability is vital to its survival . In the wilderness , discarded tegument can also avail scientists and environmentalist protect these reptiles , by pop the question telltalegenetic fingerprintsand other clues that enable them to detect threats to snake health , study population number and coinage biodiversity .
" snake in the grass tegument often contains a faint version of the radiation pattern of the Snake River and the specific number and arrangement of scale , meaning it ’s often possible to describe a specie based on a shed cutis , " Kane said .
Of all animals , snakes produce the most instantly recognisable shed specimen in the wild . But they share their throw off ability with all other reptilian , which , unlike their serpentine cousins , mostly release their tegument in fragments . There are some exception , however . For exercise , lizards from theAbroniagenus are small , flying lizard - like animal that wriggle out of their skin and leave behind a perfectly intact replication , leg and all .
