The koala is a marsupial mammal from Australia. It lives in eucalyptus trees, feeds only on their leaves, and sleeps up to 20 hours a day.
The koala differs from other marsupials with its special paws with two opposing large toes and the ability to digest toxic eucalyptus leaves thanks to special bacteria in the intestines. This animal is important for Australia's nature as it helps preserve eucalyptus forests.
