This image illustrates a specific biological phenomenon in a koala's diet: pap-feeding, where baby koalas eat a specialized form of maternal feces to transition from milk to eucalyptus leaves.
- Eucalyptus Adaptation: Adult koalas feed almost exclusively on toxic, fibrous eucalyptus leaves. To digest these leaves, they rely on a complex gut microbiome full of specialized bacteria.
- The Role of "Pap": Joeys are born without these gut bacteria. Around 22 to 30 weeks of age, the mother excretes a runny, specialized fecal substance called "pap" from her cecum.
- Gut Colonization: By eating the pap, the joey inoculates its digestive tract with the necessary microbes needed to safely break down eucalyptus toxins before transitioning to a full leaf diet.
