Geckos have billions of invisible hairs on the bottoms of their feet. These hairs are called spatulae and they work sort of like Velcro. This allows them to walk up walls and across ceilings. The more humid the air, the stickier the hairs get.

1) they are reptiles. 2) they walk up walls
Geckos can walk up walls and hang from ceilings, apparently from glass as well. This is now known to be due to the interaction of extremely small projections on the toes with the surfaces via London dispersion forces. To the gecko London dispersion forces are indeed advamtageous.

Grasshoppers are primarily adapted for jumping and are not built for walking on ceilings like some insects, such as spiders or certain beetles. Their body structure and leg mechanics are more suited for leaping than for clinging to vertical surfaces. While they can climb and may occasionally end up on ceilings, they would struggle to walk across them effectively.
Geckos can walk on walls due to van der Waals forces, which are weak attractive forces between molecules. Their feet are covered in millions of tiny hair-like structures called setae, which increase the surface area in contact with the wall. This allows geckos to exploit these forces effectively, enabling them to adhere to and traverse vertical and even inverted surfaces with ease.
It is probably the plural form of 'gecko', which is a small house lizard. It can walk on the wall and some peolpe say it is a very good cleaner of the walls and you can get rid of the cobwebs as well.
You can't walk through walls anymore on club penguin but you can walk on walls. If you download Internet explorer 7 you can walk on walls of club penguin.
You can't walk on any walls on Clubpenguin
its: 7881A409 E2026E0C walk through walls You need to type it in like this: Gameshark_v3 walk through walls 7881A409 E2026E0C Gameshark_v3 walk through walls walk through walls hope it helped XD
Depending on the book you read: increased strength, speed, durability, flight, the ability to take on a gaseous form, transforming into a bat or wolf, mesmerizing gaze, and the ability to walk on walls/ceilings.
Geckos are the ultimate climbers of the vertebrate world with the amazing ability to freely scamper around on walls and ceilings. How do they do that? Each of their toes is covered with tiny hair-like projections called, setae. The tip of each seta is covered with hundreds of very fine projections called spatulae. Each spatula has a microscopic diameter smaller than the wavelength of visible light. The spatulae stick to walls and other surfaces by van der Waals forces, an electrostatic attraction or repulsion between materials caused by the uneven distribution of the charge on their molecules. These allow geckos to cling to almost any surface without secreting a sticky substance.
