The Remarkable Self-Defense Mechanism of a Lizard’s Tail
<p>Imagine the scene — a small lizard sunning itself on a rock is suddenly startled by the lunge of a hungry snake. In a split second, its life hangs in the balance. Yet this quick-footed reptile has a hidden defense mechanism that just may tip the odds in its favor — its ability to detach its own tail through a process known as autotomy.</p>
<p>When threatened, many lizard species possess the startling ability to instinctively shed their tails via a complex pre-programmed physiological response. Specialized cells at the base of the tail enable precise separation within milliseconds upon sensing danger cues. A cascade of targeted muscular contractions and circulatory changes then act to minimize blood loss and damage from the detached appendage.</p>
