• The koala feeds exclusively on eucalyptus leaves, not consuming any other plants. This is due to the characteristics of its digestion and the chemical composition of the leaves.
• Koalas prefer eucalypts growing on fertile land because these trees contain fewer toxic substances.
• The koala's metabolism is twice as slow as that of other mammals (except wombats and sloths), compensating for the low nutritional value of eucalyptus leaves.
• The koala jumps from eucalyptus to eucalyptus with great ease and confidence, as it descends to the ground mainly to move to another tree that it cannot reach by jumping through the air.
• The mother koala excretes liquid feces composed of partially digested eucalyptus leaves, as this is the only way for the young to acquire the necessary microflora that helps digest the leaves.
• A newborn koala weighs about 5 g and is born without fur and blind. Its length ranges from 15 to 18 mm.
