<P> The diet of the green tree frog consists mainly of insects such as moths, cockroaches, and locusts . They also eat spiders and can include smaller frogs and even small mammals (including bats) among their prey . Frog teeth are not suited to cutting up prey, so the food item must be small enough to fit inside its mouth . Many frogs flick out their sticky tongues at prey and the victim sticks to the tip and is drawn back into the mouth and consumed . A green tree frog uses this technique for smaller prey; for larger items, however, it pounces, then pushes the prey into its mouth with its hands . </P> <P> 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 over 20 years . </P> <P> 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 200 and 2000 eggs are laid which initially float, but sink within 24 hours . The development of the tadpoles takes about six weeks, after which they undergo metamorphosis and leave the water as juvenile frogs . </P> <P> The green tree frog is one of the most popular pet frogs throughout the world . Its docile nature and long life expectancy make it an attractive choice for exotic pet owners . It is also one of the easier frogs to maintain; its diet is broad and it has a strong resistance to disease . One problem commonly associated with keeping this species as a pet is overfeeding; green tree frogs tend to become obese if overfed . In the wild, exertion of energy is required for a frog to capture its prey . However, in captivity, they are usually given live feed in a confined space . This lessens the activity needed for feeding, resulting in weight gain . An overweight member of the species deposits fat layers over the top of the head and body, giving it a "dumpy" appearance, thus the name "dumpy tree frog". </P>
