This species is often kept in captivity in other parts of the world where it is known by many names, including the "Dumpy" Treefrog in reference to its unusual appearance.
As can be seen in these photos, the intensity of the green coloration can vary. The calling individual seen below was quite brownish green as contrasted with the bright green individual above.
These are large treefrogs and have a correspondingly loud call. The call can be described as a loud "rork, rork, rork" that is repeated over and over at a rate of 2-3 calls per second.
Here is an individual calling from some roadside bushes in Daintree National Park, Queensland, Australia.
