The lining of the heat-sensitive pits on the face of certain boas, pythons, and pit vipers, and the outer layer of the spurs on boas and pythons are also shed at the same time as the skin. The dead layer of skin from the points of the forked tongue is shed periodically at other times than the rest of the skin.
These tongue sloughs are the length of one fork of the tongue, pointed on one end and flat on the other, and appear somewhat worm-like. They are usually found in the water bowl but may be seen elsewhere in the cage. As a snake approaches ecdysis, the skin pattern becomes dull and dark. A milky appearance is seen on the belly scutes of some species and the spectacles become milky white, obscuring vision.
To avoid damage and possible scarring, handling should be avoided and care should be taken to be gentle if handling becomes necessary.
Opaque snakes normally become inactive and hide, are quite irritable, and refuse to eat. A snake typically remains opaque for about 4 to 7 days after which the eyes become clear and actual shedding takes place 4 to 7 days after that. Snakes shed by rubbing their nose and face against objects in the cage.
As the skin comes loose it peels back over the head and neck, turning inside Out as the snake crawls out of it. The skin normally comes off in one piece. Placing a rock, brick, branch, or log in the cage may assist the snake by giving it something rough against which it can rub, but most snakes in plain cages seem to have no trouble shedding their skin.
If the skin fails to come off in one piece the condition is called dysecdysis. A snake with dysecdysis should be soaked in shallow lukewarm water for 30 to 60 minutes, and then all the remaining dead skin should be manually removed.
Snakes can drown when confined in a container with deep water, so exercise caution. An alternative to soaking is to confine the affected snake overnight in a thoroughly wetted cloth bag. All shed skins should be inspected to make sure the spectacles came off with the rest of the skin. Retained spectacles should be removed by gentle rubbing with a cotton swab after soaking or bagging as above.
Inexperienced people should never try to remove the spectacles with forceps since sometimes the entire spectacle, rather than just the dead layer is inadvertently removed. This causes corneal exposure and can cause blindness. Sometimes the last half inch of skin on the tail tip fails to come off.
If left on, it will shrink as it dries, cutting off the blood supply to the tail tip which then dries up and falls off. This piece of skin should also be gently removed after soaking. Shedding problems are more frequent in the winter when dry heat is used and there is a lack of humidity.
Cut an entry hole in the lid of the box and fill it with damp but not wet sphagnum moss from a plant nursery. If the moss drips when it is wrung out it is too wet. The skin is obviously evidence of a snake that is or has been nearby, but the skins also show a lot of detail, including the scales and where the snake's eyes were.
You can even sometimes determine the species of snake from its skin because of banding patterns and other visible markings. Shedding skin is normal in the animal kingdom.
In fact, all animals do it, according to the Iowa Department of Natural Resources. However, most animals don't shed their skin all at once like snakes do. They do it gradually. Take humans. We are always shedding skin cells — millions of them a day. But because skin cells are microscopic and it's a continual process, it isn't very noticeable.

But snakes have to do it all at once, and this is because snake skin is quite different to a lot of other animals. The dermis is filled with nerves, which is what we use to feel things touching us, as well as tiny grains called pigments, which is what gives skin its colour.
In mammals, like us, the keratin grows from a single point and keeps on growing — think how your fingernails grow from the end of your finger. But in snakes, keratin grows all over, and is stuck on top of the soft dermis, protecting it like a thin shield.
