The GREEN TOAD is by far smaller than the common toad, less than 10 cm long and its skin is less warty. Its dorsal surface is grayish or olive with darker green or olive blotches (occasional lined thinly with black) and small brick-red or red-orange tubercles. The ventral colouration is light, off-white or gray with a mottled pattern. Its iris is grayish or bluish green with black curlicues, the pupil is vertical with a bright yellow edge. On the toes it has single bulbs at the digit-joints.
During the breeding season, the males develop grayish-black nuptial pads on the thumbs, but also on the 2nd and 3rd fingers of their front legs which help them to climb and stay on the females. Males have a single, external vocal sac which may help in making a distinction between sexes.
