With night vision hundreds of times more sensitive than ours and the ability to discern color even in near total darkness, Madagascar’s leaf-tailed geckos (Uroplatus spp.) are superbly adapted as nocturnal insect hunters. Large eyes, however, demand special maintenance. Like most geckos, Uroplatus have no eyelids and cannot blink; instead, they utilize their long tongues like windshield wipers, keeping their eyes moist and clean. This is a young male Satanic Leaf-tailed Gecko (U. phantasticus), a denizen of the island’s rainforest zone and a superb mimic of dead foliage. Ranomafana National Park, Madagascar.
