White-lipped Tree Frog

Did You Know?

Its second finger is longer than its first
Often accidentally found in shipments of bananas and other produce to southern Australia, but it cannot survive the colder weather there

A ground-dwelling tree frog found in Southwest Australia. It gets its name from the male frog's mating call, which sounds like a motorbike riding past and changing gears. Other common names are Moore's frog, the western bell frog, western green and golden bell frog, and western green tree frog.

Ranges from bright green to olive to pale brown, and it can change colour depending on the local temperature and environment. It has a white (occasionally pinkish) stripe on the back of each leg that runs down to its toes, and its belly is white.
