Question

How do geckos climb walls and ceilings?

Answer 1

Geckos are able to climb walls and ceilings due to their unique toe pads. These toe pads have microscopic hairs called setae that create a strong adhesive force through van der Waals interactions, allowing geckos to stick to surfaces. This adaptation enables them to climb vertical and even inverted surfaces with ease.

Answer 2

Geckos have specialized toe pads that allow them to climb walls and ceilings. These toe pads contain millions of tiny hair-like structures called setae, which create strong molecular attractions with the surface they are climbing on. This phenomenon, known as van der Waals forces, enables geckos to stick to surfaces and move with ease in various directions.
