"Wallaby With Baby Joey" Marsupials are born after a very short pregnancy, and are very undeveloped. They are tiny, blind and have no fur. The mother licks the fur on her belly and as soon as it's born, the tiny creature climbs up along the damp fur pathway to the mother's pouch. The damp fur makes a path for it to follow and also prevents it from drying out. It is a huge journey for the tiny baby, and the mother can't touch it to help it on its way because it is so fragile.
