These lizards were common around Iguaçu National Park. The first one I saw was the handsome tree-hugging adult pictured above. Most of the others I saw were on rocks, which befits their "Lava Lizard" name. The second photo here is a juvenile on a mossy forest rock. The third photo shows one of several lizards that were hanging out on partly-submerged boulders with crashing waterfalls only a few yards away.
