The growth of snakes is the primary reason behind shedding off their skin. As human beings, when we grow, our skin expands. On the other hand, the snake’s skin shows the opposite behavior. The snake’s skin remains static instead of its growth. When they grow, their skin becomes too tight. As a result, it restricts their movements and causes some potential injuries. To accommodate its increasing size, the snakes shed off their old skin. After shedding off their skin, they reveal a fresh and pliable layer beneath.
