Every snakes skin shed looks kinda silvery when it is really fresh. As the shedded skin ages it turn a dirty yellow color.
All reptiles shed their skin. Reptile skin doesn't 'stretch' like ours does. Instead, when the current skin gets too tight, they grow another one underneath. They shed (or slough) the old skin, and the new skin allows them to grow a little more.
