We can buy frill necks for about $100, but they only display the frill under distress, and I don't want to distress my lizard to see it. I seldom see my bearded dragon's beard, because he lives a stress free life. The only thing that stresses him is when my ferrets sniff him too much. We have lots of natural lizards in Florida for insect control. I probably have a hundred in my yard alone. (Not exaggerating) They are very common. Sometimes they are in the house. Especially in winter when I bring my plants in. The eggs that were laid in the soil of my plants hatch and I end up with baby lizards all over. So I catch them and release where they will be relatively safe. I have overwintered lizards when it is too cold for them outside. The most common ones are an invasive species called a cuban anoles and our native the green anole. We also have broad headed skinks and fence lizards, but I only see those once a week or so, whereas I see 20-30 or more anoles a day. In south Florida wild iguanas, goanas and knight anoles are a major problem. They run free. When it is cold 5' iguanas fall out of the trees.
