I am always fascinated about lizard's tail still wriggling even after it's severed from their body. In fact, I have an irrational fear of it wriggling into my ear and making me deaf - thanks to my mom who used to warn me about this when I was just a kid.
Fast forward, decades later, I've finally set down to find out the answer to this burning question.
According to Wikipedia, lizards actually lose their tail on purpose (!), not by accident, in a phenomenon called autotomy, simply known as self-severing or self-amputation.
When they feel threatened, they'll discard their own tail which continues to wriggle, in order to distract their predator while they make a quick escape. The tail is said to grow back later.
There are many other animals that have such self-defence mechanism to protect themselves.
Cool right? 😁
