About the Vietnamese Mossy Frog

Theloderma corticale (common names: mossy frog, Vietnamese mossy frog, Tonkin bug-eyed frog, moss bug-eyed frog, and [for the formerly recognized Theloderma kwangsiense] Kwangsi warty treefrog) is a species of frog in the family Rhacophoridae. It is now known to be found in northern Vietnam, south–central Laos, and southern China (Guangdong, Guangxi, Hainan, Yunnan).

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 provides 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. Its natural habitats are primarily evergreen rainforests and subtropical forest where they have been found inside pools in hollowed-out logs, placed by the local villagers. The Vietnamese mossy frog is semi-aquatic and found in caves and steep rocky cliffs. This amphibian has been observed between 470 and 1500 meters above sea level. Breeding takes... Wikipedia →
