Males usually are about 50-55 mm in length, but may grow up to 65 mm. Females grow up to about 80 mm. Its large size usually distinguishes it from other species living near it. Varies highly in color: plain, pale, brown or bright leaf-green on the dorsal side with a dark line or band of yellow and brown blotches that distinctly cut off the dorsal color. Sometimes has a dark hour-glass mark on back and usually conspicuous white ridges running down the posterior sides of limbs. Sometimes very dark, nearly black, on the dorsal side without any markings, or has green or golden dorsal side with black reticulation. All have a whitish ventral surface with a varied amount of brown blotches and a fair amount of webbing between third and fourth fingers (Menzies 1975).
