Tigerbob, I'm pretty sure it's a Green Anole - also known as the American Chameleon as it can change colour from green to brown, depending on its surroundings.
the hubby agrees with you that it's a Green Anole, but never heard it called an American Chameleon before (though he also says it might well be called that, too).
Google has a couple listings as American Chameleon, but Anole seems to be favorite. That said, it looks more like a brown Anole. Not sure if they are the same. Anyway, it's an Anole of one color or another. Well done USMB Mensa members.
Now, about the frog.....
hubby says he doesn't know about the frog he never worked with them.
