An older snake may shed its skin only once or twice a year, but a younger, still-growing snake, may shed up to four times a year. [18] The discarded skin gives a perfect imprint of the scale pattern and it is usually possible to identify the snake if this discard is reasonably complete and intact.

The integumentary system includes skin, hair, scales, feathers, hooves, claws, and nails. It has a variety of additional functions: it may serve to maintain water balance, protect the deeper tissues, excrete wastes, and regulate body temperature , and is the attachment site for sensory receptors which detect pain, sensation, pressure, and ...
The regions between snake scales is made of soft integument called an alpha-layer, which is composed of alpha-keratin that allows for flexibility and movement. [10] [7] [4] Snake mobility is dependent on the skin's contact to a friction surface, the tribological behavior of the snake skin allows for quick and precise changes in direction. [6]
