How are Koalas alive?

Koalas are picky eaters, consuming mainly eucalyptus leaves directly from branches. Their smooth brains may limit their intelligence but conserve energy, which is crucial given their low-nutrient diet. Koalas have adapted to digest toxic eucalyptus leaves through specialized teeth and gut bacteria. They face little competition for food in their nutrient-poor Australian habitat. However, they are widely affected by chlamydia, a disease introduced by farm animals. Efforts to treat and vaccinate koalas against this disease are ongoing, highlighting the challenges of preserving this unique species.
