White's Green (Blue?) Tree Frog

The Australian Green Tree Frog, simply Green Tree Frog in Australia, White's Tree Frog, or Dumpy Tree Frog (Litoria caerulea) is a species of tree frog native to Australia and New Guinea, with introduced populations in New Zealand and the United States. The species belongs to the genus Litoria. It is physiologically similar to some species of the genus, particularly the Magnificent Tree Frog (Litoria splendida) and the Giant Tree Frog (Litoria infrafrenata).

The Green Tree Frog is a large species compared with most Australian frogs, reaching 10 centimetres in length. The average lifespan of the frog in captivity, about sixteen years, is long in comparison with most frogs. Green Tree Frogs are docile and well suited to living near human dwellings. They are often found on windows or inside houses, eating insects drawn by the light.

Due to its physical and behavioural traits, the Green Tree Frog has become one of the most recognisable frogs in its region, and is a popular exotic pet throughout the world. The skin secretions of the frog have antibacterial and antiviral properties that may prove useful in pharmaceutical preparations.

The common name of the species, "White's Tree Frog", is in honour of the first person to describe the species, John White. The Green Tree Frog was the first Australian frog scientifically classified. The species was originally called the "blue frog" (Rana caerulea); although the Green Tree Frog is green, the original specimens White sent to England were damaged by the preservative and appeared blue. This is because the colour of the frog is caused by blue and green pigments covered in a yellow layer. The preservative destroyed the yellow layer and left the frog with a blue appearance. The specific epithet, caerulea, which is Latin for blue, has remained the same. The frog is also known more simply as the "Green Tree Frog." However, that name is often given to the most common large green tree frog in a region, for example, the American green tree frog (Hyla cinerea).
