What is it?
So, is it...
- a baby snake
- a leech from some lettuce we just bought
- a gecko tail
- a centimeter worm (we use the metric system here)
So, what is it? Well, it is actually a gecko tail. Geckos are ravenous little skeeter eaters (they eat lots of other insects too). But just because they spend their lives eating dusty-winged moths and other mouthwatering treats, doesn't mean they don't find themselves on the other end of the fork occasionally. That is to say, geckos eat some things and some things eat geckos. Birds, other lizards and geckos, or in this case, our dog.
Our dog saw a four-legged long-tailed toy running down the sidewalk and tried to play with it. The gecko didn't care for the game, but it was a bit too slow. Our dog snipped her pointy puppy teeth right onto the gecko's tail. Ouch!
No problem. The gecko had a secret weapon...the tail is a break-away. It snaps right off like a piece of Legos. Our dog ended up with a tiny tail and the gecko ended up with a scary story to tell all the other geckos around the campfire that night.
Lots of lizards have this nifty feature. Some don't even need a dog to help snap the tail off. They can just flex their little lizard muscles and pop their own tail right off. But the tail has little muscles of its own too. And those little muscles keep twitching and flipping around so that the tail looks like a tasty treat too. While the hungry gecko-eater is getting ready to munch of the delicious market-fresh all-organic tail, the rest of the gecko is getting away and living to flee another day. This particular tail kept on dancing around for over 15 minutes after the gecko left it behind.
And how cool is this? Sometimes a bit of tail is left behind, so that little bit grows back into a full-sized tail too. Add that to the new tail it normally grows and you end up with a two-tailed gecko.
