I live in Florida and we have so many lizards! 
I know, I live in Florida too! Of course lizards can vary a lot in size from chameleons to geckos.
Yes, in my yard I have everything from the little common lizards, to iguanas, to basilisks! I wonder why lizards thrive in Florida? What do they eat?
Lizards are mainly carnivorous, often been seen-and-wait predators.
