The process through which snakes shed their skin is called ecdysis. It has nothing to do with aesthetics, although its end result may give the appearance of a more attractive creature. Various studies published in biological reviews show that this activity is linked to the development of the creature or to skin maintenance, enabling the snake's skin to change in size or environment. The glossiness that the human eye recognizes is merely due to the newly developed skin layer.
There is no fixed timeline
Another common myth is that all snakes have fixed annual cycles of shedding their skin. Studies reveal wide variations in shedding rates among different species. According to advice from veterinarians based on studies, snakes in their early years may shed often, even as often as once a month during periods of growth. On the other hand, studies carried out in the wild for species such as the timber rattlesnake have observed that the frequency can be as little as one or two times a year.

Shedding is more than skin
Shedding also correlates with various physiological activities. Research on snake skin has found that it conveys chemical messages, especially among species such as the garter snake. Thus, in addition to the protective function, snake skin may also be involved in transmitting chemical information about reproductive and behavioral activities. Therefore, one should understand that there is nothing accidental about the process of shedding, as it fits into a larger framework of activities related to growth and communication.
