We just learned about Snake Scales.
Another part of snake biology is when snakes shed their skin, called molting, sloughing or ecdysis.
Snake skin cane get dirty, worn out, and even covered with bugs like mites or ticks.
So to keep their skin fresh they will peel off the outside layer and have fresh skin and scales underneath.
Usually when a snake is getting ready to shed its skin, it goes and hides somewhere safe.
Then the new layer of skin underneath the old layer gets gooey and slippery.
The snake finds a rough or sharp thing to catch the dry outer skin on, then they keep slithering along.
Just like pulling a sock off, the snake pulls its old skin off and then goes on its way with a nice clean fresh skin.
Younger snakes can shed their skin 4 times a year, and an older snake may only shed their skin 1 or 2 times a year.
