The koala is thought to be a bear but it isn't. Its a marsupial. Well they are. The mother will have 1 young every 2 years.
Twins are rare.
The joey will stay in the mother's pouch for the next 6 months. The life span of a wild koala is approximately 10-12 years. The koalas in captivity can be 15-18 years old. Koalas live in the eucalyptus and woodland forest. Eucalyptus leaves are poisonious to most mammals, but not koalas.
