The species has been introduced to the United States and New Zealand. The frog can be found in the US state of Florida. It is believed that they were introduced through pet trade. There are only small populations in Florida. It is unknown if they have caused any ecological damage. In New Zealand, there were large populations of the green tree frog. However, there have been no sightings since the 1950s.
The Australian tree frog has a few other names like White's tree frog, or simply the green tree frog, but it's this last name we like best – the dumpy tree frog, because it is, well, dumpy. The frog was actually originally known by yet another name, the "blue frog" because a mistake in dead-specimen preservation led to the original specimens appearing to have blue skin.
I hope that you found these facts interesting and learned something new.
The green tree frog is a very calm species that is known to be nocturnal like many a frog species. It enjoys spending its days in cool, moist, and dark dwellings, and its nights hunting prey. It tends to hunt insects, spiders, smaller frogs, and small rodents, usually catching the prey with its sticky tongues and pulling it into its mouth. The frogs itself is preyed on by cnakes, lizards, and birds.
The Australian green tree frog (green tree frog in Australia, White's tree frog, or dumpy tree frog), Litoria caerulea, is a species of tree frogs. They live in Australia and New Guinea.
The green tree frog looks similar to the magnificent tree frog (Litoria spendida). This frog is native to north-western Australia. The magnificent tree frog has large patrotoid and rostral glands on the head. The giant tree frog (Litoria infrafrenata) is also sometimes confused with the green tree frog. The giant tree frog has white stripes. These stripes are on the edge of the frog's lower jaw. The green tree frog does not have these stripes.
The green tree frog was imported onto ships to the United States and New Zealand. The species belongs to the genus Litoria. The species magnificent tree frog (Litoria splendida) and the giant tree frog (Litoria infrafrenata) are similar to the green tree frog. The green tree frog is the largest frog in Australia. It can reach to 10 centimeters (4 inches) in length.
Breeding occurs between November and February. During the mating season, the males call from slightly elevated positions close to the still-water sources in which they choose to breed. Clumps of between two hundred and two thousand eggs are laid which initially float, but sink within twenty-four hours. The development of the tadpoles takes about six weeks, after which they undergo metamorphosis and leave the water as juvenile frogs.
The tree frog’s diet includes spiders, crickets lizards, other frogs and cockroaches and, when in captivity, it will even eat small mice.
Another interesting characteristic of the green tree frog is its possessing of disks on it toes which help it grip better when climbing. It also takes in oxygen through its skin despite the presence of lungs. In captivity, the green tree frog has been observed living between 16 and 20 years.
Green Tree Frogs sometimes sit beneath outside lights at night to catch insects that are attracted to the light, but they are also capable of taking larger prey on the ground, including mice. They have also been recorded catching bats around cave entrances.
I understand your mum being scared of them. I used to live in Townsville and had some jump on my legs which gave me a big fright! We also used to find them in our toilet. They are beautiful – as long as they stay away from me🙂
Green Tree Frogs are easy to take care of. They are active at night. During the day, they will rest near a place where it is cool, dark, and moist. In the winter, green tree frogs do not make calling sounds. They are also not seen that much.
The frog has a few native predators, among them snakes and birds. Since the European settlement of Australia, non-native predators have been introduced, primarily dogs and cats. The species has an average life expectancy in captivity of 16 years, but some have been known to live for over 20 years.
Green tree frogs are sometimes used as model animals in research. The structure of their toepads was used to investigate the microstructure and properties of the epithelium that allows the animals to adhere to wet surfaces.

The green tree frog is a summer and wet season breeder and will make use of all types of still water including water tanks, swimming pools, semi-permanent swamps and drainage systems. Before metamorphosing, the tadpoles may grow to about 10cm in total length.
The fungus Batrachochytrium dendrobatidis, the causal agent of chytridiomycosis, is causing declines in many species of amphibian, but it has been shown that the secretions produced by the green tree frog and certain other Australian species of frog (Litoria chloris and Litoria genimaculata) are protective against this fungus. The peptides inhibit the growth of the fungus in vitro and these frog species are believed not to be in decline.
The appearance of the green tree frog tadpole changes during its development. The tadpole can reach from 8.1 millimeters (after it has hatched) to 44 millimeters. The tadpole is brown, but it later changes to green during its development. The underside of the tadpole is dark. It changes to white when the tadpole is an adult frog. The eggs are brown, in a clear jelly. They are 1.1–1.4 millimeters in diameter.
Green Tree Frogs are one of the largest Australian frogs. The scientific name caerulea means 'blue', which was the colour of the specimen that arrived in London in 1790. The alcohol preservation may have altered the frog's true colour, fooling the early scientists. Nevertheless sometimes blue individuals are found that lack the yellow pigment and, much more rarely, yellow individuals that lack the blue pigment.
Green Tree Frogs live in urban areas, forests and woodlands, wetlands and heath. They have a habit of taking up residence in and around suburban houses, around shower blocks and water tanks.
This species is native to the tropical climates of Australia and New Geinea, and has been introduced to both New Zealand and the United States. It grows to lengths of up to 4 inches (10 centimeters) and actually varies in color from green to white. It possesses antibacterial and antiviral skin, a trait which has helped to make them extremely popular as exotic pets, and even more popular for medical research.
The frog has a few predators. They include snakes, a few species of lizards and birds. Dogs and cats have also been known to catch and eat Green Tree Frogs. The green tree frog can live up to sixteen years, if kept captive. But some have been known to live for over twenty years. The average life expectancy in the wild is lower than being captive. This is because of predation.
Larger than most Australian frogs, the Australian green tree frog reaches 10 cm (4 in) or more in length. Its average lifespan in captivity, about 16 years, is long compared with most frogs. 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. The green tree frog screams when it is in danger to scare off its foe, and squeaks when it is touched.

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.
Australian Green Tree Frog
Green Tree Frogs are one of the most widespread of Australia's amphibians, found in all states except Victoria and Tasmania.
The tadpoles' appearance changes throughout their development. When newly hatched, they are 8 mm (0.3 in) long and when fully developed, 44 mm (1.7 in). They are initially mottled with brown, and increase in pigmentation (to either green or brown) during development. Their underside is initially dark but later becomes lighter in hue. The eggs are brown and are wrapped in a clear jelly; they are 1.1 to 1.4 millimetres (0.043 to 0.055 in) in diameter.
Fireflies, genus Photinus, are poisonous to lizards, and there has been an incident when a firefly was fed to a green tree frog which subsequently died.
The Green Tree Frog is a familiar frog to many Australians and is the most popular species of pet frog overseas.

Some of the green tree frog's natural habitats have been destroyed. Some Green Tree Frogs have been found to be infected with chytrid fungus. This causes chytridiomycosis. The population of the green tree frog in Australia is declining. However, because of the long life expectancy of this species, it will take longer for the frog to be an endangered species.
Are there any other interesting facts that you would like to share about Australian green tree frogs?
During the last school holidays, I helped my mum feed the frogs from the science department at the school where she works because she was too scared to touch them. They were Australian green tree frogs and they were fun to feed.
According to the Environment Protection and Biodiversity Conservation Act 1999, the green tree frog is protected in Australia. The IUCN lists the frog as "least concern". It is listed as "least concern" because the green tree frog can be found in many places. The Green Tree Frog's population is not declining.
The Green Tree Frog population, like many frogs, has also suffered a decline over recent years. The species is long-lived and the oldest recorded captive frog died at 23 years of age. Because of this longevity the population decline went unnoticed for several years. Adults are still seen and heard regularly but young frogs are becoming scarce.
The call of a Green Tree Frog is like a 'crawk...crawk....crawk'.
Due to its appearance and behavioral traits, the green tree frog 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 and which have rendered it relatively immune to the population declines being experienced by many species of amphibian. It is a common species and the International Union for Conservation of Nature has assessed its conservation status as being "least concern".
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!
Depending on their location, green tree frogs occupy various habitats, but are not usually found in tropical rainforests. They are often found in the canopy of trees near water bodies but also occupy terrestrial habitats well away from water. They favor old stands of Eucalyptus where the trees have hollows in which water collects. They are common along inland waterways and can survive in swamps (among the reeds) or in grasslands in cooler climates.
