There are a number of iquanas that live among the rocks in a pond behind our daughter's house in Davie, Florida. Most stayed hidden during our recent visit, but I spied this fellow sitting up on a rock sunning himself. When he observed me coming closer, he hunched down over the rock perhaps to hide from perceived danger.
He was still at a distance, however, which made a good photograph difficult. I'd guess he's about four feet long.
