Okay so I think it's pretty common knowledge that a lot of lizards can drop their tails if they need to get away from something. I was having a good old stoner think about it just now and the logistics of that are FUCKING CRAZY. Like how for one?!? How do you just drop your tail!?! Physically how?!?! Is it an opened wound after? It must be, right? Does it ever happen by mistake like if they get startled? Can you imagine someone sneaks up and gives you a scare and your fucking arm falls off?! Like "Well thats just great Patrick! Now I've only got one arm for the next 8 months!"
Just wild...
I've never heard of them just dropping off, more like it easily comes off. I've got blue belly and Alligator lizards and see a couple of the blues missing tails every year but rarely the gators, but it does happen. Yes, it's like a open sore but clots, little if any blood, heals quick and then grows back, never like it was. They don't live that long, most of them anyway but you can always tell if they had lost their tails at one time and they can break anywhere from the base down.
It's been a long time since I was the cause of a lizard loosing a tail. I can't even find a pic of one missing a tail. Not really all that common.
And when they do come off they wiggle like worm to keep thr predator busy while the lizard escapes.
