Many animals, including humans, shed their skin. Snakes will normally shed their skin in one piece. If they have difficulty in removing all or part of this skin serious problems and death may result. Normally, when a snake starts the shed (slough, dysecdysis) process, its pattern and colours become dull and its eyes go milky white. This condition is called by herpocultureists 'being opaque'. It is caused by a secretion coming between the outer and under prepared for the shed, the opaque condition subsides and the skin pattern and colours look normal again. within a few days after this clearing colours, the snake should hope fully shed in one piece.
