Fast Facts: Geckos – Part V

Carl Kerby

Welcome to Fast Facts with Reasons for Hope. I’m Carl Kerby.

Have you ever noticed how a gecko can run across any surface – even slippery ones without falling? In order to accomplish that seemingly impossible feat, it needs perfectly designed . . . FEET! Yes, every square millimeter of a gecko’s adhesive footpad contains about 14,000 nanoscale hairs called “setae.”  There are millions of them, and each one ends with a smaller structure called a “spatulae.”

These amazingly thin hairs allow the gecko to stick to almost anything. The “spatulae” are also self-cleaning so nothing clogs them up to slow the gecko down. Unbelievably, these structures automatically release as the gecko moves so they’re not stuck in one place.

This is a God design that even humans can’t perfectly recreate. We’ve copied it, though, to improve everything from medical bandages to self-cleaning tires.

Geckos are awesome!  But they’re just one of God’s amazing creations.  There’s even more for next time!  Until then, stay bold!
