316:. The ventral skin is smooth, pale to white, the dorsal skin colour is variable, generally shades of brown with darker blotches. Similar blotches form bars across the upper surfaces of the thighs. Often it has a vertebral line in a lightly contrasting colour, pale to reddish. Some colour variants have a broad russet band down the back. The dorsal skin is textured with scattered small, raised ridges, largely longitudinal. The tympanum is smaller in diameter than the eye, but more than half the diameter. Though clearly visible, it is inconspicuous, being situated in a dark facial band of pigment behind the eye. The facial band extends more or less from the nostril, across the lower part of the eye, rearward over the tympanum, to the base of the fore leg. From below the eye, a pale line runs below the facial band to the shoulder. Above the band a light line runs from the snout, across the eye, above the pupil, rearward to the shoulder.
437:. In the breeding season, its voice is an inoffensive musical click, rather like a drop of water falling into a pond, but when a large chorus is active, such as in sedge around a dam, the effect is like a loud, continuous rattle. Though the males mainly sing in chorus at night, they may call at any time of the day from concealment, particularly in cloudy weather. Like most frogs, the species breeds in standing water and the adults take to the water if alarmed. They can swim rapidly and with agility, but if they are unable to leave the water, they die within a few hours. Rather than simple drowning, the cause of death seems be absorption of too much water through the skin.

The toes are well developed and unwebbed, or nearly so, on all four feet. The front toes are slim and roughly as long as the fore legs are thick. The rear toes are long, with the longest (fourth) toe extending forward roughly as far as the front toes when the frog is squatting.
