eli5 how do bugs stick to walls???

Like spiders, or ants, or just anything that can stick to walls?? Lizards too!! How??
gpt
They all have their own variation of surface-area increasing adaptations that allow them to stick to walls. Like lizards have a bunch of tiny ass hairs on their feet that allow them to stick to walls and ceilings. Suction cups, tiny hairs, and claws are the main adaptations that allow tiny animals to climb shit.
