People have been amazed by the phenomenon for millennia and have been trying to figure it out for as long. They have many tiny hairs per foot called setae, each of which splits off into hundreds of even smaller bristles called spatulae. We now know that a gecko's feet are covered in microscopic hairs. Despite everything we've learned, little is known about the detailed surface chemistry of gecko toe pads, particularly the setae. And what did I see, but toe-gate!, I didnt feel a thingnot a thing.
