why can lizard crawl on ceilings and walls?​

Sagot :

Answer:

They have adhesive foot pads

Explanation:

Lizards have adhesive foot pads which have tiny hairlike structures known as setae covering the base of its toes. When these tiny hairs (setae) get close to the ceiling and wall, their hair electrons make temporary bonds with the electrons from the ceiling and wall.

Because these hook-like cells are bent downward and to the rear, the lizard curls its toes upwards to disengage them. Thus while walking or running on horizontal or vertical walls, a lizard curls and uncurls its toes thus creating a suction pressure which enables it to cling on to the walls.
