The COMMON TREEFROG grows to approximately 5 cm. Its skin is smooth and bright on its dorsal surface, and granular on the ventral side. The male has dark-yellow or brown wrinkles on the throat which indicates the large, single guttural vocal sac, which can be inflated as big as the whole body. The female lacks the vocal sac, its throat has the same colouration as the belly, usually off-white, without wrinkles. The species has a prominent, round tympanic membrane. The treefrog has long limbs and adhesive discs at the end of its toes. The treefrogs are able to change their colours, they are usually bright green, but they can turn to grey or brown depending on temperature, humidity, or their mood. The dorsal and ventral colouration is separated by a blackish lateral stripe from the eyes to the groin.
