Koala Bear documentary.
When Australia separated from Gondwanaland, it was like a giant Noah's Ark adrift on the seas, and the animals on it had to adapt in isolation from the rest. The trees also adapted, particularly the eucalyptus tree, which quickly spread. The Koala bear managed the impossible: it adapted to the point where all it eats are eucalyptus leaves. Eucalyptus leaves are poor quality food, indigestible and full of toxins, but the koala has managed to survive on them. Their digestive process is long, and the koalas go about their business without wasting any energy. This is part of their metabolic strategy. They can survive on only 16 ounces of leaves a day.
The young koalas suckle in the marsupial bag until they are 6 months old. When they are weaned, they are initiated into the art of leaf eating. After weaning, the young koalas leave their mothers to live on their own in these woodlands.
