Satanic Leaf Tailed Gecko This is one scary looking lizard! Geckos typically have slightly satanic eyes, all the better to see in the dark with. But the Satanic Leaf Tailed Gecko takes it several steps further. This is a particularly good example, where the eyes are blood red and the tattered skin is the colour of burns and battle. Other individuals have more subdued brown colors with eyes to match. It provides them with some astonishing camouflage in their Madagascan home.
