Gecko's tail has the function of regeneration.

Gecko's tail is thin and long. Gecko can use it to defend itself.

Gecko's tail, when hurt by the enemy, will automatically break and leave it to the enemy. There are many nerves in the tail, which can jump for a period of time to divert the enemy's sight, but you can take the opportunity to escape.

When the gecko crawls on the wall and glass, its abdomen and tail are tightly attached to the wall, and its head is slightly raised upward to observe the surrounding environment. The metacarpal bones of the forefoot and the tarsal joints of the fingers, and the tarsal joints of the hind feet are also attached to the wall. The metacarpal bones and legs are lifted up to support the whole body weight, which can drive the metacarpal bones (toes), tarsal joints and hind feet to crawl forward. When the gecko crawls, there is a rule that the left front foot and the right rear foot are raised and stretched forward almost at the same time. At this time, the head is facing the upper right and the long tail is facing the lower left. Then the right front foot and the left rear foot are lifted at the same time and stretched forward. At this time, the head is facing the upper left and the tail is facing the lower right. The whole body is "S" or "S" shaped. Gecko's crawling style has played a role in balancing the body. The gecko's crawling is mainly accomplished by the alternating movement of its front and rear feet.
