Uroplatus sikorae is a species of gecko commonly referred to as the mossy leaf-tailed gecko. The mossy leaf-tailed gecko ranges in size from 15 to 20 centimetres (6 to 8 in) when measured from nose to base of the tail. Their eyes are large and lidless, and have yellow sclera with elliptical pupils, suited for the gecko's nocturnal habits. As with all Uroplatus geckos, the tail is dorso-ventrally flattened. U. sikorae has coloration developed as camouflage, most being grayish brown to black or greenish brown with various markings meant to resemble tree bark; down to the lichens and moss found on the bark.
