Gray Tree Frog, they can change colors: It takes around a half hour for an individual to change color. They do so by controlling the pigment in their star-shaped skin cells. Though they can only go from green to gray and back again, they can also control the intensity of the dark splotch pattern found on the back. The sides appear to stay gray for the most part regardless of the chosen back color. Against natural settings, Gray Tree Frogs are masters of camouflage.
Synapturan De Miranda-ribeiro (Synapturanus mirandaribeiroi) lives under leaf litter and in holes in the ground in humid tropical forests at low elevations. They lay large, terrestrial eggs, which develop into non-feeding tadpoles on the ground (they don't develop in the water like most tadpoles).
