Australian marsupial eating mainly eucalyptus leaves (from where it gets its water since it doesn’t drink or do it rarely); the koala spends most of its time in trees. A female koala can produce one Joey (baby koala) which stays 6 month into the downward-facing pouch of its mother. Hunted for its fur before it became the Australian national emblem, it stays threatened by the destruction of its living area in Australia. On the other hand, in certain isles or part of the country, where they don’t have any predators, koalas can be a threat to the ecosystems.
