The mossy leaf-tailed gecko ranges in size from 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.
U. sikorae has flaps of skin, running the length of its body, head and limbs, known as the
dermal flap, which it can lay against the tree during the day, scattering shadows, and making its outline practically invisible.
