Adapted for a life high in the rainforest canopy, these small amphibians are slender with long limbs, have webbed toes, and measure just over two inches long. Large suction-like disks on their fingers and toes help them grip tree bark, and a claw-shaped final digit enables these frogs to climb trees that are more than 100 feet tall. They are active at night; during the day, their bright green bodies and lemon-yellow underbellies camouflage them among the leaves. Their eyelids are bright red or orange.

During the rainy season (October through February) in their range, males climb down from the canopy and gather in flooded grasslands, outdoor water tanks, or even neglected swimming pools. They then call out a series of long “aaa-rk” calls. Females—the larger sex—choose their mates based on the males’ calls, preferring the best singers. Fertilization occurs in the water and females will lay up to 500 eggs among aquatic vegetation. The tadpoles are light brown and, depending on local conditions, they complete their metamorphosis into adults in 40 to 45 days. As with most amphibians, populations are threatened by habitat loss and negatively impacted by local pesticides and fertilizer.


These small frogs are found in high canopy rainforests and wet deciduous forests along the eastern coast of Australia.


A typical tree frog menu includes small insects, spiders, mites, and even smaller amphibians.

Physical Characteristics

Average adult tree frog body length is between 2.1 and 2.7 inches. Females are a bit larger than males. Their lifespan in the wild is unknown, but in human care, related species have an average lifespan of 16 years.
