Lizards climb with the use of suction

Fact

Lizards actually have van der Waals interactions between their setae footpads that stick them to the surface. A single foot contains 500,000 setae, these organisms being able to adhere to almost anything, apart from liquids. The setae are self cleaning, as to remove dirt from preventing the lizards to climb. The only surface they cannot stick to is the Teflon.
