We were at Iguazú to see the spectacular waterfalls, but of course I was looking for lizards too. Earlier in the day I had seen a half dozen or so of these huge tegus strolling about while I was in a moving car or tram. I was beginning to worry that the day would end without me getting a decent photograph of this species. Fortunately in the afternoon we walked past a few that were willing to sit still for me.
