Koala diet overview
Koalas (Phascolarctos cinereus) are best summarised as Herbivore (eucalyptus specialist). Anatomy and habitat (Eucalyptus forest and woodland) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How koalas find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Koala role in the food web
As herbivores shaping plants and seeds, koalas move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild koalas. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
A specialized leaf diet
Koalas eat almost nothing but eucalyptus leaves, which are tough, low in nutrients, and toxic to most animals. A special digestive system lets koalas break down these leaves and neutralize the toxins. Because the diet provides so little energy, koalas sleep up to 20 hours a day to conserve it.
Life in the trees
Koalas are superbly adapted to life in the canopy, with strong limbs, rough paw pads, and two opposable thumbs on each front paw for gripping branches. They rarely come down to the ground, where they are slow and vulnerable, and they get most of their water from the moisture in leaves.
