Snakes shed their skin through a process called ecdysis, also known as molting. This process is necessary for snakes to grow and remove old skin that may have parasites or injuries. Before shedding, snakes develop a new layer of skin underneath the old one. They then rub against rough surfaces, such as rocks or branches, to help loosen and shed the old skin. This process allows snakes to emerge with a fresh layer of skin that is more flexible and vibrant.
