Question

How lizards stick to the wall??​

Answer 1

Lizards have a large number of very tiny hairs on the pads of their feet called setae. These hairs have tiny pads at their tips known as spatulae, which are about one-tenth of a human hair in diameter. Instead, they need to slide their feet into position.

Answer 2

Geckos can stick to surfaces because their bulbous toes are covered in hundreds of tiny microscopic hairs called setae. ... Scientists already knew that the tufts of tiny hairs get so close to the contours in walls and ceilings that the van der Waals force kicks in.
