The bodies of snakes are covered with scales. Without this protective armor, snakes could not move over rough or hot surfaces; like tree bark, rocks, and hot desert sand. Their scales are also nearly waterproof and help to keep the water out. of its skin Rough belly scales allow the snake to keep their grip on rough branches and to push off of surfaces when they need to move.
Snakes have powerful muscles all along the front half of their bodies. Snakes use these muscles for moving as well as swallowing. The muscles move the food down along the throat and into the snake’s long stomach. Moving the food through the throat into the stomach can take 15 minutes to an hour, depending on the size of the animal they are eating.
In egg-eating snakes the sharp rib bones will poke through the eggshell to help speed along digestion. Food in the snake’s stomach can take anywhere from a few days to a couple of months to breakup or digest. That is a long time to work on a meal!
