The green tree frog is usually a beautiful bright green, though, depending on the mood of the frog, this may sometimes fade to a dark khaki-green. Some specimens also have white spots that are outlined in darker colours. The underside is creamy-white. In its adult stage, a female green tree frog may reach almost 12cm in length. Males are much smaller and less robust than the females. The green tree frog is distributed through the eastern and northern parts of Australia. It prefers cool damp places and, particularly in more arid areas, will often use human habitation for shelter. It is well known for its habit of hiding under the rim of outback toilet bowls!
