The koala is Australia's national treasure and a rare and precious primitive arboreal in Australia. The English name Koala bear comes from the ancient indigenous script, meaning "no drink". Because koalas get 90% of the water they need from the eucalyptus leaves they feed on, they only drink water when they are sick. The locals call it "Kevler", which means "do not drink water."  Koalas are not bears. The bear family belongs to the carnivora, while the koala bear is an herbivore. It sleeps for 18 hours a day, has a gentle temperament and a thick body. It is a very cute animal.
