Wallabies

Wallabies are mammals. A mammal is an animal which breathes air, has a backbone, and grows hair at some point during its life.
The rock wallaby is a small kangaroo. There are 15 species of rock wallaby. They live exclusively on rocky terrain and can leap up to 4 metres (13 feet), but cannot climb trees.
During hot weather, wallabies spend most of the day in the shade, searching for grass to eat in the early morning and evening. On cooler days, they spend much of their time eating.
Wallabies communicate warnings to others by thumping once or twice on the ground with their feet.
Female wallabies can produce two different kinds of milk at the same time – one for her baby and another, richer blend for her older offspring.
Wallabies can swim.
Wallabies are pink and hairless at birth.
