as child I grew up in Cuba in an area near the coast , lots of threes in our back yard, I had so many of this lizards along with others, I can't claim is from Cuba, but for sure I have yet to see one in Florida, I would suggest, go to a Cuban website, under "Flora Cubana" it would tell you about of the species that are from there. Cuba does have many diferent species of animal, that are only found there, like the cuban cocodrile, the smallest bird, Zun Zun like a huminbird, smallest frog, and more. One of my favoritye videos on enviroment is from PBS library "Cuba, eden by accident" it is very stonning what our horrible enemy (according to some) is doing way better than us, and lots of other countries to protect the enviroment, air , water, plants and animals

Thank you, lazygardens...I just couldn't reconcile the head color and I didn't think about molting. Here's a photo of another one the same day...more typical. Thanks again! Pam

It might help if you could at least narrow it down to what continent it was seen on. It is a lizard, clearly. It might be one of the spiny-tailed Iguanas (Ctenosaura) or even some sort of Old World lizard in the family Agamidae. There introduced populations of of both groups in areas of the US and of course they are found in their native countries. Without knowing where you were there is no way to narrow it down further. I would consider this as dangerous as a small bunny rabbit, i.e. not at all.

Very interesting! Thanks for sharing Warren.
