This guy was a baby, only about an inch long. We saw it and the one following along the Mastic Trail. We first tried the West end of the trail but after slogging through ankle deep water for 1/2 a kilometer or so, we gave up. The East end of the trail turned out to be much drier and quite an interesting walk, although very hot. We even saw a couple of wild parrots.
This one was on the wall beside our hotel room. I think it's a Green Anole.
And this one is a captive endangered Blue Iguana at the Botanical Gardens.
Common Iguanas are much more, well, common, like this one leaving a parking lot.
