Dear Mr. Science,
Why do snakes shed their skin?
Jessica, age 10
Thanks for your question! Snakes shed their skin in order to grow. The snake begins to grow another layer of skin, under their old layer, and the top layer begins to fall off or shed. Their new layer of skin has the same scales and pattern as their older piece of skin. They also shed to replace old or worn scales with new healthy skin. Snakes shed more when they are young and growing quickly but they continue to grow throughout their lives.
Interesting fact: When rattlesnakes shed their skin, they get a new piece added to their rattle. In fact, when rattlers are first born they only have one piece on their rattle, called a button. Their rattles are noiseless until they shed for the first time and a new piece is added to their button to make a rattle!
Keep those questions coming!
GET OUT and GET DIRTY!
