Theloderma corticale is a species of frog in the family Rhacophoridae. It is found in northern Vietnam and China, and possibly also in Laos. Its common name, the mossy frog, arises from the fact that its skin is a mottled green and brown that resembles moss growing on rock, forming an effective camouflage. It has large sticky pads on its toes and a soft underbelly, with a snout–vent length of 61 millimetres (2.4 in). The females grow larger than the males and can reach sizes of 8 to 9 centimetres (3.1 to 3.5 in). When frightened, it will curl into a ball and play dead. This T. corticale frog was photographed at Karlsruhe Zoo in Germany.Photograph credit: H. Zell
