Gecko lizards possess a fascinating defense mechanism known as autotomy, enabling them to shed their tails. When a gecko perceives a threat, it can contract its tail muscles, resulting in the formation of a fracture plane between the tail and the rest of its body. Through this process, the tail breaks off, and specialized muscles and blood vessels constrict to minimize blood loss. The detached tail continues to exhibit wriggling and twitching movements, diverting the attention of predators and granting the gecko an opportunity to escape. Eventually, the gecko's tail regenerates, although the newly grown tail may not reach the same length or possess the same attractiveness as the original.
