The tadpoles' appearance changes throughout their development. It can be distinguished from the white-lipped tree frog(giant tree frog N. infrafrenatus ) by the distinct white stripe that species has along the edge of the lower jaw and extending to the shoulder, which is not present in the green tree frog. The parotoid gland of the green tree frog is much smaller, and it also lacks the yellow speckling on the back and the yellow markings on the hand, groin, and thigh. Older members of that species have very large parotoid glands, which cover the entire top of their heads and droop over their tympana. This frog is similar in appearance to the magnificent tree frog ( R. splendida ), which inhabits only north-western Australia. The ventral surface in both sexes is creamy-white and rough in texture. Males have a greyish, wrinkled vocal sac under the throat, while the throat of females is white. The frog occasionally has small, irregularly shaped white spots on its back. The dorsal colour depends on the temperature and nature of the environment, ranging from brownish- or greyish-green to bright emerald green. The fingers are about one-third webbed, and the toes nearly three-quarters webbed. The limbs are short and robust, and large adhesive discs are at the end of the digits which provide grip while climbing. The iris is golden and has a horizontally slit pupil, and the tympanum (a skin membrane similar to an eardrum) is visible just behind the eye. A distinctive fatty ridge is seen over the eye, and the parotoid gland is moderately large. The green tree frog is a plump, rather large tree frog, and can grow up to 11.5 cm (4.5 in) in length, with fully grown females being slightly larger than males. It is a common species and the International Union for Conservation of Nature has assessed its conservation status as being 'least concern'. The skin secretions of the frog have antibacterial and antiviral properties that may prove useful in pharmaceutical preparations and which have rendered it relatively immune to the population declines being experienced by many species of amphibian. The green tree frog screams when it is in danger to scare off its foe, and squeaks when it is touched.ĭue to its appearance and behavioural traits, the green tree frog is a popular exotic pet throughout the world. Docile and well suited to living near human dwellings, Australian green tree frogs are often found on window sills or inside houses, eating insects drawn by the light. Its average lifespan in captivity, about 16 years, is long compared with most frogs. Larger than most Australian frogs, the Australian green tree frog reaches 10 cm (4 in) or more in length. It is morphologically similar to some other members of its genus, particularly the magnificent tree frog ( R. splendida ) and the white-lipped tree frog ( R. infrafrenata ). The Australian green tree frog ( Ranoidea caerulea ), also known as simply green tree frog in Australia, White's tree frog, or dumpy tree frog, is a species of tree frog native to Australia and New Guinea, with introduced populations in the United States and New Zealand, though the latter is believed to have died out.
