Eucalyptus are trees unique to Australia. Their leaves are the main diet of koalas. 桉树是澳大利亚特有的树。它们的叶子是树袋熊的主要食物。

Koalas live in trees and are rarely found on the ground. They do not drink often. They get most of their water from the Eucalyptus leaves. 考拉生活在树上，很少在地面上被发现。他们不常喝水。它们需要的大部分水分来自桉树的叶子。

Koalas have fingerprints which look the same as human fingerprints. It is difficult to tell if the prints are from a human or koala. 考拉的指纹和人类的指纹看起来简直一模一样。很难分辨一些指纹是来自人类还是考拉。
