Southwestern people call it "four-legged snake", "gecko" and "lizard". The back and abdomen of the body are flat, and the body surface is lined with granular scales or mixed with warty scales. Fingers and toes expand, forming skin folds under them, which are densely covered with glandular hairs. They have adhesion ability and can crawl quickly on walls, ceilings or smooth surfaces.

Gecko is an animal that lies in the daytime and comes out at night. Lurking in hidden places such as cracks in the wall, under the eaves of tiles and behind cabinets during the day, and coming out at night. On summer and autumn nights, geckos often appear on walls, eaves or telephone poles illuminated by lights, preying on mosquitoes, flies, moths, spiders and other beneficial and harmless animals.

When the gecko is frightened or catches it, as soon as it touches it, its tail will be broken immediately and the gecko will run away. This phenomenon is called "self-cutting" in zoology, also known as "self-cutting", "self-mutilation" and "self-cutting".

Because the broken tail has many nerves, after it leaves the body, the nerves don't lose their function immediately, so it still swings, playing a scary role, and sometimes it can achieve the purpose of self-defense.
