“Our findings highlight the intricate mechanisms behind tail autotomy in lizards,” said Professor Song. “By studying the regenerative abilities of their tails and the role of mushroom-shaped micropillars, we gain valuable insights into the natural defense strategies of these fascinating creatures.”
The Initiation of Autotomy
Using high-speed cameras, the researchers also observed the initiation of the autotomy process. They found that the bending of the tail plays a crucial role in triggering tail shedding. When a lizard perceives a threat, it rapidly bends its tail in a way that generates stress on specific points. This stress leads to the activation of the autotomy process, resulting in the tail breaking off or dropping.
Understanding the intricate mechanisms behind tail autotomy in lizards has significant implications beyond the realm of scientific curiosity. This knowledge has the potential to inspire advancements in fields such as medicine and robotics. The regenerative abilities of lizard tails, combined with the understanding of how they break off or drop, could pave the way for breakthroughs in regenerative medicine and the development of more robust and adaptable robotic systems.

The Initiation of Autotomy
The initiation of autotomy in lizards involves the bending of the tail, triggering the shedding process and allowing for tail loss when necessary. A recent study led by NYUAD Associate Professor Yong-Ak Song has shed light on the mechanisms behind this fascinating phenomenon. Using high-speed cameras, the researchers captured the moment when lizards’ tails start to break off, providing valuable insights into tail autotomy.
One of the key findings of the study was the role played by mushroom-shaped micropillars covered with nanopores. These unique structures, found on the surface of lizards’ tails, provide additional support and help facilitate shedding. The micropillars are designed in a way that allows the tail to detach easily when the lizard needs to escape from a predator or other life-threatening situations. However, they also display remarkable toughness, keeping the tail attached in non-life-threatening situations.
The bending of the tail is the crucial trigger that initiates the autotomy process. The researchers observed that when the tail is bent at a certain angle, it creates stress on the connection between the tail and the rest of the body. This stress causes the micropillars to break, leading to the detachment of the tail. This mechanism not only allows lizards to escape from potential danger but also ensures that they can regenerate a new tail afterwards.
The understanding of tail autotomy in lizards has wide-ranging implications. From a scientific perspective, it provides valuable insights into the regenerative abilities of lizards, which could have implications for medical research and tissue engineering.
