Unique animals of Australia

Koala bears are seen as having the most enviable life. The tree dwelling animal often spends 16 to 18 hours a day asleep and the rest of the time eating. Eucalyptus tree leaves are the only food for koala bears but it offers little energy, which results in its sleep until you eat, and eat until you sleep lifestyle. The population of koalas was estimated as below 80,000 in 2015 with a declining trend. [File photo: baidu.com]
