Waterfall frog
The Australian waterfall frog or torrent treefrog (''Litoria nannotis'') is a species of tree frog native to Far North Queensland, Australia. The common name "waterfall frog" is indicative of its habitat of moist, rocky streams, and is often found along waterfalls within its range.
==Description==
The waterfall frog is large in size, reaching 5.5 cm in length. The dorsal surface is mottled with puck brown. The patterning on the back is similar to its habitat, allowing for effective camouflage against granite. The ventral surface is bright orange, green, and pink in colour, and granular. The posterior ventral surface is translucent, showing internal parts.
The toe pads of ''L. nannotis'' are very large in comparison to toe width, to aid in gripping to rocks in the rapids. The nuptial pads of breeding males are also large, covering the entire inner surface of the thumb, with spines also present on the arms and chest. The tympanum is not visible, the fingers are partially webbed, and the toes are completely webbed.
Like the stoney creek frog (''Litoria wilcoxi''), and many other stream-dwelling frogs, waterfall frogs lack vocal sacs. This may be because the sound of a running stream drowns out any calls, and it becomes a waste of energy.
