The gecko is a small reptile belonging to the family Squamiidae, the reptilia. The body is slender, usually between a few centimeters and a dozen centimeters in length, and the surface of the body is covered with tiny scales and various colors. There is a special suction cup structure at the bottom of the toes, which enables the gecko to crawl easily on vertical walls, ceilings and even smooth glass surfaces. The tail is slender and easy to break. When in danger, the tail will automatically fall off, which can confuse predators and regenerate after breaking the tail. It is a nocturnal animal, mainly feeding on small arthropods such as insects and spiders. Sharp eyesight, able to catch fast-moving prey in the dark.

It is a small reptile belonging to the gecko family of the lizard order. Known for its unique ability to walk freely on vertical walls and even hang upside down from the ceiling. There are thousands of tiny hairs on the soles of the feet, which can generate van der Waals forces with the surface, allowing them to adhere to smooth surfaces. Usually active at night, feeding on insects such as mosquitoes and flies. Highly sensitive to environmental changes, it is often used as a symbol of ecological health. Their regenerative ability is also very strong. If their tail is caught, they can cut off their tail on their own to escape predators, and then their tail can grow back.
