Vietnamese mossy frog (Theloderma corticale)

The common name "mossy frog" arises from the fact that its skin is a mottled green and brown that resembles moss growing on rock, and forms an effective form of camouflage. They have large sticky pads on their toes and a soft underbelly. They measure about 61 mm (2.4 in) in snout–vent length. The females will grow larger than the males and can reach sizes of 8–9 cm (3.1–3.5 in). This species will curl into a ball when frightened, and play dead.
