The pouches of female koalas are resistant to microbial colonisation, with a majority of pouch swabs revealing no microbial growth The koala also has the option to store leaves in the cheek pouch before chewing it (9). Since eucalyptus is of low nutritional value, high toxicity and high dietary fibre (4), then the koala can regurgitate its food. As a hindgut fermenter the digestive retention of the koala may be up to 100 hours in the wild, and twice as long in captivity The pouch is actually situated in the centre of the female's abdomen and the opening faces straight outwards, rather than backwards. However, the pouch opening is towards the bottom of the pouch, so when the joey is larger and puts its head out of the pouch it can appear that the pouch faces backwards A Koala is born: When the mother Koala gives birth, the little joey Koala makes its way to the pouch all by itself, with no help from its mother
