Reptiles, such as lizards or geckos can stick in the ceiling, walls, or slippery surfaces, such as glass.
Why is that??
On the surface of the foot reptile, there are billions of tiny hairs called spatulae.Spatulae they form structures called setae.Setae line resulted in adhesion force (attractive forces between the surface smooth hair). Therefore, lizard or gecko can stick to a.Interaction molecules (between hair smooth with the surface) only happens when a lizard or a gecko sticks to the surface (not permanent). therefore, lizard or gecko could move.
