The snake It is an enigmatic reptile, shrouded in thousands of legends and myths, which gives us one of the most captivating spectacles in nature: its change. A process that, beyond being a simple renewal of the skin, represents a silent dance of transformation, a periodic rebirth that intimately links it with the cycles of life. Maybe, just maybe, the molting of these animals is an unfinished manifestation that immortality is possible.
Shedding, or ecdysis, is a biological process that all snakes experience periodically throughout their lives. A phenomenon that may seem strange at first glance but is essential for the growth and health of these animals.
As with other reptiles, snakes do not grow continuously, their skin – made up of scales – does not expand naturally and acts as a prison. And as the animal grows, its skin becomes small and narrow, limiting its movement and making its vital functions difficult. It is precisely this reason that makes molting necessary: getting rid of the old, tight skin to make way for a new, larger and more flexible one.
Molting is necessary for a healthy life
Snakes’ skin is their first line of defense against the outside world. During their daily activities they may suffer small cuts, scrapes or infections, so shedding gives them the opportunity to eliminate these damaged areas and regenerate new healthy skin.
Additionally, old skin can accumulate external parasites, such as mites or fungi. By shedding, snakes get rid of these organisms, reducing the risk of infections.
In some species, shedding may be related to reproduction: before mating or laying eggs, some snakes shed to ensure they have healthy, flexible skin that facilitates these processes.
The shedding process
Shedding is a gradual process that can last several days. During this time, the snake undergoes a series of changes, from physiological to behavioral. It has been observed that before molting the snake increases the production of an enzyme that separates the new skin from the old, while its eyes become opaque and its skin takes on a milky appearance.
It has also been scientifically proven that when the snake is ready to molt, it usually looks for a moist and safe place, stops eating and is much more irritable.
As the new skin begins to form under the old skin, the snake rubs itself against the rough objects in its path to encourage the process, which can last for several hours. In the end the old skin comes off with a single push, it is as if the snake was taking off a sock that is oppressing it.
Although this process is similar for all snakes, the frequency of molting varies depending on the species, age, and environmental conditions. Young snakes have been observed to molt more frequently than adults, as they grow faster; and that high temperatures accelerate the snake’s metabolism, increasing the frequency of molting. Lastly, if the environment is too dry the snake’s skin can stick to the snake’s body and make the shedding process difficult.
