This Australian frog has a secret weapon: a large, liquid-filled poison sac on the back of its head is filled with a bitter tasting fluid that it uses to deter predators. It is the largest poison gland on any Australian amphibian. Defensive measures are necessary because small amphibians, like this frog, are on the menu of almost every predator in Australia, including larger amphibians, reptiles, birds, and mammals. The poison is not toxic to humans.

Like all tree frogs, the magnificent tree frog has long legs and extra muscles for climbing, however it rarely spends time in trees. Instead, it uses large toe pads and a claw-shaped last digit to scale caves and rock crevices. A nocturnal lifestyle helps protect the frog from drying out. During the day magnificent trees frogs are commonly found near showers, toilets, drainpipes, ponds, and even in mailboxes looking for a cool, moist place to rest. During the rainy season, these frogs are often found on windowsills hoping to ambush insects attracted to the light at night.


Magnificent tree frogs live on the northwestern coast of Australia and are typically found on rocks and in crevices and caves.


This frog’s carnivorous diet includes insects, earthworms, spiders, and small lizards.
