Quick answer
Koalas feed as Herbivore (eucalyptus specialist), adjusting with season, age, and local prey or plant availability.
Key takeaway
Koalas feed as Herbivore (eucalyptus specialist), adjusting with season, age, and local prey or plant availability.
Diet overview
Koalas (Phascolarctos cinereus) are best described as Herbivore (eucalyptus specialist). That label summarises preferred foods, not every item an individual might sample.
How they obtain food
Foraging and hunting strategies reflect anatomy and habitat. Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel.
Seasonal and life-stage shifts
Young koalas often eat different foods or receive provisioned meals from parents. Adults may specialise regionally based on what is abundant.
Ecosystem role
As herbivores and seed/plant processors, koalas influence prey, vegetation, or nutrient cycling.
Human conflict
Do not feed wild koalas. Habituation raises injury risk for people and animals and can lead to lethal management.
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.
Raising a joey
Like other marsupials, koalas give birth to a tiny, undeveloped joey that crawls into the mother's pouch to keep growing. After about six months it begins riding on her back. Young koalas eat a special form of their mother's droppings to gain the gut microbes needed to digest eucalyptus.
Conservation
Koalas are listed as Vulnerable, and populations in parts of eastern Australia are declining sharply. Habitat loss, bushfires, disease, vehicle strikes, and dog attacks are the main threats, and protecting and replanting eucalyptus forest is central to their recovery.
Research notes
Figures for koalas (Phascolarctos cinereus) come from field studies, museum records, and conservation assessments that do not always agree on exact averages. Prefer ranges over single-point claims, and check whether a source describes wild, captive, or mixed populations.
Practical takeaways
If you encounter koalas in the wild, prioritise distance and local guidance. If you care for related domestic or captive animals, match diet and housing to species needs rather than generic pet advice. Share accurate status information (Vulnerable) when discussing conservation.
