Koalas get most of their moisture from eating juicy eucalyptus leaves, but they’re limited by how much they can eat. And that is one of many Interesting facts about koalas I’m going to share with you today. Scientists experimented with fecal transplants by encapsulating feces from koalas who did eat messmate and feeding it to the koalas who only chewed manna gum. Why shouldn't they sleep all day if they want to? The Koalas' ultimate evolution took place some 15 million years ago, when Australia's drought tolerant plantations i.e., Eucalyptus emerged and the koalas thrived on them. (we call these "primary browse trees") while a variety of other species, including some non-eucalypts, appear to be browsed occasionally or used for just sitting or sleeping in.

Even so, the Koala is still only able to absorb 25 per cent of fibre eaten. The toxins are thought to be produced by the gum trees as a protection against leaf-eating animals like insects. These leaves are actually toxic so koalas need to waste evolution points on teaming up with certain gut bacteria. The little teddy bears would not accept anything else on their plate. The upside to the sounds is that they can travel longer distances – they act like the long waves of AM radio instead of the shorter waves of FM.
