But sitting out in the open comes with a price – lizards are easily spotted by predators such as snakes, hawks and meat-eating mammals.
When attacked, one way lizards survive is to “drop their tail”. The predator holds on to or goes after the wriggling tail, while the lizard makes good his escape. Better to lose your tail than your life.
But this survival tactic is costly for the lizards – they’re less mobile (because their weight distribution changes) and, even more importantly, less likely to attract the ladies.
Not all lizard species are equally quick to shed their tails. Scientists have been fascinated by this phenomenon and want to know “why” – why are some species more quick than others and why did this technique develop in the first place. One theory has to do with “predator pressure”: the more lizard-eaters there are, the more likely this defense technique will occur.
But recent studies have discovered that all predators are not created equal; it is the number of venomous predators that determines how quickly the lizard will drop their tail. Which only makes sense: those lizards who react slowly will drop dead before they drop their tail.
Quick – drop something and run – is an effective technique for evading all kinds of predators. This became personal for me last year, when I got a phone call at 5:30 in the morning. It began, “Mom, I’m OK but…”
Our daughter, who lives in Philadelphia, had been robbed at knifepoint on her way to work.
Although my heart was in my throat, I managed to keep my voice calm (at least I thought I did), “Tell me what happened.”
“Well, I opened my wallet, took out the money, threw it on the ground and RAN!”
I don’t know if she learned this lesson from watching lizards or if she remembered the training she had received in a self-defense class. I’m just thankful she put it to good use.
