Snakeskin

We had a great opportunity last week for the children to see and handle a snake skin shed by one of our parent's pet snake, they all has a sssssssuper time :o)




Scales are made up of layers of cells stacked one on top of the other. The outer cells are dead and protect the living ones underneath them.  A few times every year a snake will shed a layer of dead skin. The cells underneath are then ready to take over as the outer layer.

When a snake is ready to shed it’s eyes get cloudy and it is temporarily blinded. Why? Because snakes eyes do not have eyelids (that’s why they don’t blink) but instead are covered with a clear scale called a spectacle.  When a snake is ready to shed its old skin it will rub up against a rough surface, like a rock, to rip the skin and then slide right out. Just like taking off a sock!



Did you know ...  that a Snake’s scales are made up of something called Keratin, which is the same thing that our fingernails are made from!!
